Spiral Wound Gaskets

Spiral wound gaskets for pressure-temperature flange service, available in standard classes, materials and project-specific configurations.

Product overview

Spiral wound gaskets are semi-metallic gaskets made from alternating layers of profiled metal winding and a soft filler. This construction provides resilience during pressure and temperature cycling and makes them a common choice for raised-face and other industrial flange connections. Styles, winding metal, filler and inner/outer rings are selected to suit the flange and service.
