1 in (25 mm) Spiral Wound Gasket, Class 150 | LGSW15025
Available
This AAP spiral wound gasket is made for Class 150 flanges (manufacturer-stated) and is supplied in 6 sizes from 1 in (25 mm) to 6 in (150 mm).
AAP describes spiral wound gaskets as 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.
The stock configuration is an SS316 spiral with graphite filler, and AAP gives a maximum working temperature of 450 °C because graphite is the filler. Other material and class combinations are available on request.

Selecting the right option
AAP's catalogue does not give a pressure rating for these gaskets, and does not say which stock sizes include an outer guide ring, so contact AIMS if you need either. The 6 in size is 4.85 mm thick and the other sizes are 3 mm, so check the flange face and the compression you are designing for. The 4 in dimensions are out of line with the neighbouring sizes, so confirm them with AIMS before ordering. For a different winding, filler or class, contact AIMS.
