Spiral Wound Gasket With Inner and Outer Ring

Spiral wound gaskets have proven to be the most reliable sealing element for use in difficult, critical and arduous duties. Spiral wound gaskets are used in Refinery, Petrochemical, Chemical, Steam lines and Process Industries, where they have many advantages over older types of gaskets.

Spiral wound gaskets with outer ring are manufactured to International specifications such as BS, API, ASME, DIN. We also manufacture to customer's specifications. We have a huge capacity to produce precision machined components.

Spiral wound gaskets with outer ring are manufactured of a spiral-wound metal strip and a non-metallic filler material. The metallic outer centering ring controls the compression and holds the gasket centrally within the bolt circle. The inner retaining ring increases the axial rigidity and resilience of the gasket.
