Leader Spiral Wound Gasket Type SRI
Description
Designed more than 100 years ago, Spiral Wound Gaskets (SWG’s) are widely used as high integrity and sustainable gaskets. The sealing element is manufactured from preformed, V-shaped metallic windings with intermediate soft sealing fillers. Most used filler materials are Graphite and PTFE or LeaderTHERM NXT 1000 (high temp. modified Phlogopite). Due to the gasket construction, SWG’s offer high compressibility and recovery. Leader Style SRI SWG’s are provided with an innerand outer guide ring. These gaskets are suitable for ASME B16.5 raised faced flanges up to 2500 lbs and for EN/DIN flanges up to PN400.
