20 300# 304 SS AND GRAFOIL RW S/W GSK

The 7GSW4B2000 is a yellow 304 Stainless Steel Class 300 Spiral Wound Gasket built to a 20 inch nominal pipe size and a Class 300 pressure rating. This spiral wound gasket alternates metal windings with a soft filler so the gasket recovers elastically through thermal and pressure cycling.

This material stands up to chemical attack, elevated temperature, and corrosion and oxidation. 304 Stainless Steel is specified for dimensional stability under thermal cycling and long service life in demanding outdoor environments. Exposure to galvanic pairing with dissimilar metals or chloride stress cracking in some grades will shorten service life.

Common environments for this compound include marine and offshore, food and beverage processing, and chemical transfer.

Reference part number 7GSW4B2000 when ordering; the item is sold individually. Unit weight is approximately 5.56 lb. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
