3 150# 304 SS AND GRAFOIL RW S/W GASK

Part number 7GSW4A0300 is a yellow 304 Stainless Steel Class 150 Spiral Wound Gasket measuring a 3 inch nominal pipe size and a Class 150 pressure rating. A spiral wound gasket delivers high-integrity sealing on critical flanges where pressure and temperature fluctuate.

The material holds up against salt water and washdown, elevated temperature, and high pressure. That behavior comes from the compound itself: 304 Stainless Steel is known for dimensional stability under thermal cycling, excellent corrosion resistance in washdown and marine service. Verify compatibility before use with chloride stress cracking in some grades or galvanic pairing with dissimilar metals.

Typical settings include pharmaceutical, chemical transfer, and petrochemical.

This item is sold individually under part number 7GSW4A0300. Unit weight is approximately 0.38 lb. Check the compound against your process media, pressure and temperature before committing to a design.
