What Industries Use Custom Gaskets?

With so many types of gaskets available for almost every type of machinery, you may wonder why any company would need a custom designed gasket. There is a whole world of commercial and industrial gaskets that are used in a wide range of equipment and machines.

Since a large amount of industrial equipment and machinery is proprietary and often custom designed, they may not be compatible with standard gasket sizes and are likely to require custom gaskets to match the needs of the complex machinery.

While a gasket is a part used in nearly all industries in some form, there are a few industries that tend to use custom gaskets more than others.

Industries that Use Custom Gaskets:

  • Original Equipment Manufacturers (OEM): OEMs face a multitude of challenges designing equipment. From construction applications to marine applications, the equipment is often exposed to extreme environments requiring custom design and materials. Expert Gasket & Seal is the one-stop-shop for OEMs.
  • Food Production: Food production often requires specialty materials that conform to FDA requirements so that foods are not exposed to any potentially toxic chemicals or contaminants. We call these FDA Gaskets.
  • Pharmaceutical Industry: Similar to the food industry, pharmaceutical manufacturers adhere to strict quality control, along with full compliance with FDA requirements. More information can be found on our FDA Gaskets page.

  • Oil and Gas Industry: With the oil and gas industry dealing almost exclusively with fluids and gases, it’s only natural that they are a heavy user of gasket products. Gaskets used in the oil and gas industry often need to be capable of withstanding extreme pressures and exposure to corrosive substances.
  • Auto Manufacturing: Auto manufacturing features a wide range of machinery used for many different purposes along the manufacturing process. Plant machinery often requires more unique custom designed products.
  • Power Generation: Power plants come in a wide range of varieties, most of which involve fluids and turbines. The result is that gaskets are needed for the critical power generation equipment as well as many other parts within the power generation facility.
  • Paper Processing: Paper processing involves of the use of water and chemicals, requiring the use of pumps. This means that custom designed gaskets are an important part of keeping the plant running smoothly.
  • Wastewater Treatment: As one would expect when dealing with water, gaskets are needed to seal the many pumps that are used to move wastewater from one area to another. Much of this requires custom-designed gaskets.
  • Chemical Processing: Like the oil and gas industry, chemical processing requires management of potentially toxic and corrosive chemicals. As a result, gaskets are needed that can withstand exposure to a wide range of chemicals.

Overall, Gaskets Are Used Everywhere

Gaskets are used in some way in just about every industry. While not all industries need to have custom gaskets produced for them, they always have the option to go the custom route if it suits the job better.

Expert Gasket & Seal Fixes Leaky Filling Equipment, Saving Hundreds of Hours for Solvent Manufacturer

A solvent leak can become very costly, very quickly — not to mention dangerous, as it involves hazardous waste. Any leak not only presents risks to production and equipment, but it also puts the health and safety of employees at risk. So, when a solvent manufacturer was experiencing leakage during their filling process, they turned to Expert Gasket & Seal for a solution.

The solvent manufacturer was filling small quart cans with its product using precision filling equipment that filled by weight and volume. During production, the seals which regulated the flow of the solvent experienced a major leak resulting in underfilled cans, the loss of finished products and hazardous material exposure to the workplace.

Expert Gasket & Seal assessed the situation and recommended replacing the dynamic O-ring with an energized PTFE seal. The new seal was energized by a Perfluorelastomer O-ring for its chemical resistance, and the machined PTFE seal jacket provided a friction-free seal with wiping action and with little to no seal wear or leakage.

With the PTFE design, the seal was not wearing out like the plain dynamic O-ring and there was no longer a need to continually stop production to replace faulty O-rings. And this was all done with existing hardware without the need to retrofit the machined components of the equipment.

The filling equipment consisted of 24 filler heads. Expert Gasket & Seal’s expert sealing solution increased the life of each filler by hundreds of hours, allowing the manufacturer to extend the production schedule and cut downtime by at least four times over.

3 Reasons Why Quick Turnaround Gasket Manufacturing Matters

The demands of a business may change daily but working quickly to meet customer needs is always essential. Continually improving processes and having quick turnaround time is key to meeting those needs.

Having an experienced team with comprehensive fabrication equipment and dedication to great service allows our customers to meet production expectations while still being able to exceed industry standards. Industrial organizations requiring quality sealed products to prevent leaks must be able to tackle challenges with speed and efficiency.

Here are three reasons why having quick turnaround gasket manufacturing matters.

Avoid Manufacturing Downtime to Save Time and Money

Every business has times where service or production must stop to allow for maintenance or upgrades. But when this happens as an unplanned event­ — and too many times — it can damage reputation and frustrate customers. High temperatures, for example, can weaken integrity of gasket materials and lead to increased downtime. The chances of this happening can be decreased by selecting the right material. Having more precise products with higher tolerance levels for equipment can lead to less downtime, leading to less operational waste.

Make Changes and Adjustments Quickly Without Losing Efficiency

One reason companies turn to custom gaskets for their equipment is that the customized approach allows for different materials to be tested to determine the best result and ensure efficiency. Making changes and adjustments is quick and easy with rapid prototyping. While traditional gasket production requires templates or steel dies, which can double the time for production, Expert Gasket & Seal can create prototypes from a digital file or an existing product sample. If a gasket doesn’t fit or changes need to be made, dimensions, thickness and materials can be rapidly modified and easily reconfigured. This allows for quicker testing, easier deployment and less time and waste spent designing before mass production.

Prevent and Reduce Production Bottlenecks

Inefficiencies created by bottlenecks are a source for delays and higher overall production costs. Maintenance professionals face daily problems including keeping machines running and scheduling and overseeing maintenance. For production related to gasket or rubber products this becomes a matter of having updated processes and technologies working alongside well trained employees. With a modernized approach and a focus on proactivity, machines can be kept running and bottlenecks prevented.

Reducing waste and improving processes and quality of materials will lead to higher customer satisfaction. Expert Gasket & Seal understands how manufacturing and maintenance projects require quick yet effective services. Our Flashcut system effectively creates custom gaskets in minutes without the need for tooling. Ultimately this yields greater results for our customers who keep choosing our proven sealing solutions again and again to help them excel in their industry.

Expert Gasket & Seal Replaces Faulty O-Ring With Custom Gasket to Protect Valuable Equipment

An O-ring can fail for different reasons. Maybe it’s made from the wrong material for the application, or it is not compatible with the O-ring groove design. When an international healthcare products company came to Expert Gasket & Seal with an O-ring that repeatedly fell out, we got to work to provide a customized solution.

The company was using an O-ring in a groove to seal a two-piece cast aluminum electrical enclosure that protected a delicate circuit board from environmental elements — rain, snow and other potential contaminants. The irregular O-ring groove on the casting used a very small cross section O-ring that was difficult to install and often fell out after installation. After the enclosure was assembled it was impossible to see if the O-ring had become dislodged. Without the proper seal, the circuit board was no longer protected and was subject to premature failure.

Expert Gasket & Seal fabricated a new gasket from a closed cell Neoprene sponge (CCNS) with a peel and stick, pressure-sensitive adhesive (PSA) backing to bond the elements without the use of the groove. The PSA backing kept the gasket in place during assembly significantly decreasing installation time.

Our recommendation and the prototype gasket which was fabricated in-house were supplied in only a few days using our rapid Flashcut system.

With the new custom gasket, labor and installation time was decreased, and the risk of assembly failure was eliminated, providing a substantial cost savings to the healthcare products company.

High-Temperature Gaskets and Why They’re Important — Can Your Project Stand the Heat?

When you’re working with extreme high temperatures, flames, steam, hot oils, exhaust or combustible fluids, you need a seal you can trust. Using the right gasket, tape or material can be the difference between the success or failure of your equipment.

Over time, high temperatures can gradually degrade and deteriorate some common gasket materials causing leakage which in turn can lead to downtime, and maybe even shutdowns. Expert Gasket & Seal can help you avoid these situations by finding the right material for your high temperature sealing needs.

We understand “high-temperature” is a relative term. If your application is below 500° F, there are several great rubber materials to consider, like:

Heat Resistant Gasket Materials

Silicone: With a superior temperature range from -75° F to 450° F, silicone good choice when the material will not be exposed to acids, alkalis, superheated steam (over 250 degrees F), aromatic hydrocarbons and certain fuels.

Viton®: An excellent choice for high temperature applications up to 400° F, Viton® has superior resistance to many chemicals, including acids, fuels, aromatic hydrocarbons, chlorinated hydrocarbons and not flammable hydraulic fluids.

EPDM: Considered the best rubber gasket for steam and hot water applications (up to 350° F), EPDM is capable of handling steam temperatures up to 400° F. Although EPDM is not compatible with petroleum-based fluids, it can handle many Glycol-based fluids up to 300° F.

Perfluoroelastomers: Most commonly available in O-rings, perfluoroelastomers, often known as Kalrez® or Parofluor®, are heat resistant up to 600° F and handle a wider array of chemicals than Viton®. However, they are very expensive and come in limited shapes and sizes.

If your application involves higher temperatures, up to or exceeding 750 degrees, you should consider other materials to enhance and extend your seal’s performance. Some considerations include:

Graphite: A natural mineral, graphite has thermal and electrical conductivity like metal and is resistant up to 875° F.

Compressed non-asbestos: An asbestos-free fiber made from synthetic fibers and an elastomeric binder, compressed non-asbestos gaskets provide improved torque retention, lowered emission levels and can handle temperatures up to 750° F.

Spiral wound gaskets: A low-cost solution, spiral wound gaskets are semi-metallic, consisting of multiple layers of metal and a filler that may include ceramic, graphite or PTFE. Spiral wound gaskets are suitable for temperatures up to 850° F.

PTFE: Polytetrafluoroethylene is a reliable polymer material that can resist strong industrial chemicals and withstand temperatures above 500° F for extended periods.

Commercial Grade Fabrics: For the most demanding applications with extreme high temperatures, consider premium fiberglass cloth, rope, tape, and tadpole tapes with temperature ratings up to 1000° F or ceramic fiber papers, some with temp limits of 2300° F. Used in furnace linings, casting blow off tables, molten metal or anywhere you need to protect product and parts from high temperature or molten materials.

While it is important to consider high-temperature materials, there are many other factors to consider when selecting the most suitable gasket for your application, like the medium, system pressure and exposure conditions. The experts at Expert Gasket & Seal will work with you to identify these factors and help you choose the right materials and products for your project.

Expert Gasket & Seal Helps Client Combat Equipment Failure While Maintaining FDA Compliance

At Expert Gasket & Seal, we don’t just provide sealing products, we provide sealing solutions. Our customer’s success is our priority. So, when an international food manufacturer came to us with major equipment failure of one of their cooking vessels, we tackled the challenge with open minds and ready hands.

The large steam cooking vessel was designed to go from the ambient plant temperature to 250 degrees Fahrenheit steam. The steam was injected through a tube that also served as the shaft to which the seal was attached. Because the shaft we were sealing was also the heating element, the axial shaft would grow .250“-.375“. This expansion was causing almost instant failure of the mechanical seal from stretching, rolling O-rings and shattering hard seal faces.

Working with Advanced Sealing International (ASI), our experts designed a custom double mechanical seal, based on ASI’s Model 600, which allowed for the necessary shaft growth without destroying seal faces or damaging plant equipment. Designing the custom mechanical seal required focus on several factors other than the equipment failure. We needed to design a seal that would address factors like minimizing the use of water being wasted as the barrier fluid, frictional heat, the set up and crystallization of the sugars in the product on seal faces during downtime, product loss and waste, product contamination and of course the safety of plant personnel — all while maintaining FDA compliance.

This new custom mechanical seal increased the life of the equipment’s seal from around 2-6 weeks to 1-4 years — that’s an average increase of nearly 3,000 percent. Considering that it takes around eight hours to replace the drive end and thrust end of the vessel seals, increasing the seal life has resulted in a reduction in downtime, increased production, increased safety and decreased collateral equipment damage.

Is CAD Needed to Prototype Custom Gaskets, Seals and Other Parts?

Traditional manual gasket production requires creating templates or steel dies, doubling the time to manufacture the gasket. When gasket designs are computerized and run through CAD software, small alterations to gasket designs take much less time and do not require dies or re-tooling, making them ideal for prototyping and perfecting your design before mass production. For prototyping purposes, having CAD designs ready to go for the parts you need is ideal. But what if you dont have a CAD file or drawing to start with?

Maybe you have a product sample and need to prototype two-dimensional gasket from the sample, or maybe you created a gasket manually, without a CAD file, that you need to duplicate. Expert Gasket has a solution that is both fast and accurate at replicating products without design files.

Gasket Prototyping Without CAD Files Via Optical Scanning

Along with our Flashcut technology, we utilize a high-tech optical scanner that allows us to make a 3D scan of the product or component sample and build a computerized model (CAD file) from the physical sample.

This scanner enables you to capture your object’s shape and geometrics quickly and accurately through millions of XYZ data points and provides thorough measurement data of the entire surface of your object, creating a complete digital representation of your part and verifying that the part matches your CAD model.

Once your CAD model is complete, your prototype can be created with our die-less Flashcut system. This entire process allows for fast, accurate results while shortening your time to market and reducing labor and material costs.

Rapid Gasket Scanning and Prototyping for Any Application

Expert Gasket & Seal provides cost-effective, rapid prototyping for most flat gasket non-metallic applications.

What Are Mechanical Seals?

Mechanical seals are seals are typically used on rotating equipment such as pumps, compressors, and mixers. They keep potentially hazardous gas and fluids that are being processed from contaminating the environment. Keeping these materials away from plant personal and vulnerable equipment. devices that form a barrier around moving parts to prevent contamination from the outside, and to keep components within the device from leaking.

Common Types of Mechanical Seals

Cartridge Seals

Single Cartridge Seals are seals that are factory assembled so they avoid any field installation issues. They are preassembled components composed of a gland, sleeve, faces, and springs. All the components are factory pressure tested and have pre-set spring tension. These are basically bolt on seal.utilize two flat surfaces that slide against each other and are held together by a spring. They are pre-constructed and ready to use, which minimizes installation and maintenance.

Double Cartridge Seals are seals similar to single cartridge seals, but use two separate seals positioned next to each other to reduce or eliminate any leakage of fluid from the interior of the device chamber. Double cartridge seals are also ready-made to be used with minimal installation and maintenance effort. These seals maintain the lowest leak rates possible for fugitive emissions, environmental contamination and safety to plant personal.

Component Seals

Single Spring mechanical Seals utilize two separate components that are field assembled. The spring & face rotate together and run against a stationary seat to seal off process fluids. The single spring provides the load or pressure that holds these faces together.

Multiple Spring Mechanical Seals are built in the same way that single spring seals are built with the exception that they utilize multiple springs to ensure uniform distribution of force to keep the seal shut. This helps to reduce leaks and wear and tear on the seal.
Non-Metallic Cartridge Seals are similar to single cartridge seals with the exception that they do not use metallic components. These are often used when the fluids being sealed off would cause corrosion or damage to the mechanical seal.

Related Seals

Bearing Isolator Seals are seals designed specifically to prevent external contaminants from damaging bearings, and to keep bearing lubrication from leaking out of the bearing.

How Are Mechanical Seals Used?

Mechanical seals are typically used on pumps of all different varieties. Pumps typically need to seal off fluid contained within the pump while also allowing motion to be transferred away from the sealed chamber. This usually involves a rotating shaft. The problem is that this opens up potential for fluid to leak where the shaft connects from the exterior of the pump to the interior chamber. Mechanical seals help to prevent these leaks and seal the fluid inside the chamber without hindering the moving components’ motion.

Mechanical seals are used across an enormous range of industries and applications. Any industry that involves moving fluids will likely use pumps that require mechanical seals, and many other industries also regularly use mechanical seals.

Industries that use mechanical seals would include:

  • The Oil Industry
  • Chemical Industry
  • Food and Beverage Processing
  • Utilities and Wastewater Processing
  • And many more
