12 150# 316L SS & GRAFOIL RW S/W GASK

This spiral wound gasket is supplied in green 316L Stainless Steel Class 150 with a 12 inch nominal pipe size and a Class 150 pressure rating, catalogued under part number 7GSW6A1200. It alternates metal windings with a soft filler so the gasket recovers elastically through thermal and pressure cycling.

Expect good resistance to elevated temperature, salt water and washdown, and corrosion and oxidation. That behavior comes from the compound itself: 316L Stainless Steel is known for dimensional stability under thermal cycling and a hygienic, cleanable surface suited to sanitary process lines.

Maintenance and OEM teams specify it across chemical transfer, food and beverage processing, and pharmaceutical.

7GSW6A1200 ships individually. Unit weight is approximately 1.75 lb. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
