1/2 900-1500# 304 SS AND GRAFOIL RW

Part number 7GSW4E0050 is a yellow 304 Stainless Steel Class 900/1500 Spiral Wound Gasket with a 0.5 inch nominal pipe size and a Class 900/1500 pressure rating. A spiral wound gasket alternates metal windings with a soft filler so the gasket recovers elastically through thermal and pressure cycling. The catalog record notes: S/w Gasket.

304 Stainless Steel is specified here for high mechanical strength and pressure capability, excellent corrosion resistance in washdown and marine service. Expect good resistance to high pressure, salt water and washdown, and corrosion and oxidation. Exposure to galvanic pairing with dissimilar metals or chloride stress cracking in some grades will shorten service life.

You will find this material specified across marine and offshore, chemical transfer, and pharmaceutical.

7GSW4E0050 ships individually. Unit weight is approximately 0.25 lb. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
