3 300-400-600# 304 SS AND GRAFOIL RW

APG stocks the 7GSW4B0300, a yellow 304 Stainless Steel Class 300/400/600 Spiral Wound Gasket built to a 3 inch nominal pipe size and a Class 300/400/600 pressure rating. A spiral wound gasket alternates metal windings with a soft filler so the gasket recovers elastically through thermal and pressure cycling. Source specification: S/w Gasket.

304 Stainless Steel is specified here for dimensional stability under thermal cycling and long service life in demanding outdoor environments. It resists corrosion and oxidation, chemical attack, and salt water and washdown. It is not the right choice where chloride stress cracking in some grades or galvanic pairing with dissimilar metals are present.

It sees regular use in food and beverage processing, pharmaceutical, and marine and offshore.
