Style CG - Outer Ring

Spiral Wounds » Style CG - Outer Ring

The CG spiral wound is the original standard spiral wound gasket per ASME B16.20. The CG style spiral wound is fitted with an outer centering ring that accurately centers the gasket on the flange face, provides radial strength, and acts as a compression limiter. The outer ring is typically made from painted carbon steel, but other corrosion resistant materials are available like stainless steels and other higher temperature alloys. The CG is a general purpose gasket suitable for use with flat face and raised face flanges.
