AAP spiral wound gasket, 1"

This AAP spiral wound gasket is made for Class 150 flanges and is supplied in 6 sizes from 1" (25mm) to 6" (150mm). Spiral wound gaskets are a preformed metallic strip and a softer filler material, wound together under pressure, optionally with an outer guide ring. The metal strip holds the filler, which gives excellent mechanical resistance, resilience and recovery.
