1 1/2" 150# 304 SS & GRAPHITE RWI

The 7GSW4A0150IR is a yellow 304 Stainless Steel Class 150 Spiral Wound Gasket with a 1.5 inch nominal pipe size and a Class 150 pressure rating. This spiral wound gasket delivers high-integrity sealing on critical flanges where pressure and temperature fluctuate. The catalog record notes: S/w 304 S.s. Inner Ring.

It resists high pressure, corrosion and oxidation, and chemical attack. That behavior comes from the compound itself: 304 Stainless Steel is specified for excellent corrosion resistance in washdown and marine service, dimensional stability under thermal cycling. It should not be specified for service in galvanic pairing with dissimilar metals or chloride stress cracking in some grades.

You will find this material specified across marine and offshore, food and beverage processing, and pharmaceutical.
