*4" 300# 316 SS & GRAPHITE RWI

APG stocks the 7GSW6B0400IR, a green 316L Stainless Steel Class 300 Spiral Wound Gasket supplied with a 4 inch nominal pipe size and a Class 300 pressure rating. A spiral wound gasket alternates metal windings with a soft filler so the gasket recovers elastically through thermal and pressure cycling. Additional detail on this item: 316L S.s. Inner Ring - C/s Outer S/w.

316L Stainless Steel offers high mechanical strength and pressure capability, excellent corrosion resistance in washdown and marine service. Expect good resistance to elevated temperature, salt water and washdown, and chemical attack. Exposure to chloride stress cracking in some grades or galvanic pairing with dissimilar metals will shorten service life.

Typical settings include chemical transfer, marine and offshore, and pharmaceutical.

Reference part number 7GSW6B0400IR when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
