Spiral Wound Gaskets Color Codes

Spiral wound metallic gaskets used on standard ANSI pipe flanges are color coded on the OD edge to identify their winding & filler materials.  The most common is a yellow painted edge with a pink stripe.  This signifies a 304 stainless steel winding and Mica-Graphite filler.

Another common winding is 316 stainless steel with a flexible graphite filler.  Its color code is a green painted edge with a gray stripe.  There are many others spiral wound gasket color codes.   Please contact us for a color code chart that identifies the various combinations.
