Spiral Wound Gasket with inner and outer ring, Material: 1.4541/PTFE/Carbon Steel

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

The inner and outer support ring [inner ring: 1.4541, outer ring: carbon steel, corrosion protected] stabilize the spiral, while the outer ring also ensures the centering between the flange bolts.

Spiral Wound Gaskets are particularly suitable for applications with high operating pressures and critical operating conditions [e.g. alternating loads].
