Spiral Wound Gaskets
GASKET IDENTIFICATION GUIDE RING COLOR CODING
COLOR CODING FOR THE GASKETS YOU NEED. Gaskets are color coded to help expedite the selection and identity of the gaskets you
need. The color on the outside edge of the centering ring identifies both the winding and filler materials. The metallic winding material is
designated by a solid color. The filler materials are designated by color stripes at equal intervals on the outside edge of the centering ring.
Flexitallic color coding meets the industry standard for metal and filler materials listed in ASME B16.20.
