Introduction
Gaskets incorporating a spiral wound V-shaped lamina with the interposition of a soft sealing material. The V-shape of the lamina provides higher elasticity under any operating condition. An appropriate choice of materials is fundamental for best sealing performance. Standard configurations according to:

Gasket type SW S
Plain spiral-wound gasket, normally used for groove joints that do not require a limitation of compressive loads.
Gasket type SW E
Spiral-wound gasket with external centering ring for improving the gasket aligment on raised joints as well as for limiting the compressive load.
Gasket type SW I
Spiral-wound gasket with an internal containment ring improving the gasket's mechanical strength particularly on joints subject to the action of highly turbulent media.
Gasket type SW IE
Spiral-wound gasket with internal and external rings, ideal for heavy-duty applications as well as for limiting compressive loads and preventing the medium from damaging the spiral interior.
