The Spiral Wound Gasket consists of a spirally wound, beaded metal strip made from stainless steel 1.4541. A graphite soft material strip [purity 98%C] protruding on both sides is inserted between the individual windings.

The outer support ring [material: carbon steel, corrosion protected] stabilizes the spiral on the outer diameter and also ensures the centering between the flange bolts.

Spiral Wound Gaskets are particularly suitable for applications with high operating pressures and critical operating conditions.
