How to Choose Rubber Gasket Thickness
When choosing the gasket thickness for compressed materials, remember that thinner is better. Most compressed sheet gasketing sealing values are based on 1/16” thickness. Thicker materials require a greater compressive force to seal and have lower pressure ratings. The use of 1/16” thick gaskets will provide better sealing with lower bolt loading than 1/8” thick gaskets. Thinner is better!
