Seals pressures to flange ratings, in accordance with ASME B16.5
Suited to temperatures from cryogenic to 2000°F / 1093°C, depending on metal and filler
Custom-tailored solutions accommodate a variety of conditions by combining various metals and filler materials
Centering ring accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter
Spiral winding (sealing element) consists of preformed metal and soft filler material
NOTE: Per ASME B16.20 all spiral wound gaskets for ASME B16.5 or B16.47 flanges are made with outer and inner rings (FLEXSEAL® RWI) unless specified by the customer at the time of order. .
