Spiral Wound Gaskets

Spiral Wounds are made of a preformed thin metallic strip combined with a soft sealing composite material wound together under pressure to energize the sealing element to act like a spring when compressed between two flange faces. The sealing element can be used as a stand-alone winding or in conjunction with inner and/or outer rings depending on the application.
