Spiral Wound Gaskets are manufactured of special V-shape metallic strips and a soft filler material wound together in a special process. They are available with several material combinations for steel and filler materials as well as different designs.
BPG 9336 Spiral Wound Gaskets are widely used for flange sealing in high temperature and high pressure applications. Spiral Wound Gaskets show excellent performance in load-bearing as well as non-load-bearing installations.
