Spiral Wound Gaskets

CHAMPION SPIRAL WOUND METALLIC GASKETS consists of the basic sealing element combining several layers of pre-formed V-shaped metal strip which are spirally wound together under pressure with the soft- material filler (PTFE or expanded Graphite) to improve the mechanical strength and internal pressure. This gasket provides perfect sealing under fluctuating high pressure operating conditions (thermal Cycling) providing resilience and recovery.
