1/2" 300/400/600# 304 SS & GRAPHITE RWI

This spiral wound gasket is supplied in yellow 304 Stainless Steel Class 300/400/600 built to a 0.5 inch nominal pipe size and a Class 300/400/600 pressure rating, catalogued under part number 7GSW4B0050IR. It alternates metal windings with a soft filler so the gasket recovers elastically through thermal and pressure cycling. This item is further identified as S/w 304 S.s. Inner Ring.

The material holds up against high pressure, chemical attack, and elevated temperature. 304 Stainless Steel is known for a hygienic, cleanable surface suited to sanitary process lines and dimensional stability under thermal cycling. It is not the right choice where galvanic pairing with dissimilar metals or chloride stress cracking in some grades are present.

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