4 1500# 304 SS AND GRAFOIL RW S/W GSK

The 7GSW4F0400 is a yellow 304 Stainless Steel Class 1500 Spiral Wound Gasket built to a 4 inch nominal pipe size and a Class 1500 pressure rating. This spiral wound gasket combines metallic strength with a conformable filler for demanding flange service.

It resists chemical attack, salt water and washdown, and corrosion and oxidation. 304 Stainless Steel delivers dimensional stability under thermal cycling and a hygienic, cleanable surface suited to sanitary process lines. Exposure to galvanic pairing with dissimilar metals or chloride stress cracking in some grades will shorten service life.

It sees regular use in chemical transfer, marine and offshore, and food and beverage processing.
