Ordered as 7GSW4A1000IR, this is a yellow 304 Stainless Steel Class 150 Spiral Wound Gasket measuring a 10 inch nominal pipe size and a Class 150 pressure rating. The spiral wound gasket alternates metal windings with a soft filler so the gasket recovers elastically through thermal and pressure cycling. Source specification: S/w 304 S.s. Inner Ring.
304 Stainless Steel is specified here for dimensional stability under thermal cycling and long service life in demanding outdoor environments. The compound resists chemical attack, high pressure, and corrosion and oxidation. Exposure to galvanic pairing with dissimilar metals or chloride stress cracking in some grades will shorten service life.
It sees regular use in marine and offshore, pharmaceutical, and chemical transfer.
This item is sold individually under part number 7GSW4A1000IR. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
