Spiral Wound Gasket with inner ring, Material: 1.4541/Graphite

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 inner support ring [material: 1.4541] stabilizes the spiral on the inner diameter. This gasket type has no outer support and centering ring and is suitable for the use in male-female flange systems.

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