Leader Spiral Wound Gasket Type SI
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. As standard metallic material for winding and inner ring SS316L is used and for the soft fillers, graphite, PTFE or LeaderTHERM NXT 1000 (high temp. modified Phlogopite). Due to the gaskets construction, SWG’s offer high compressibility and recovery. Leader Style SI SWG’s are provided with an inner ring. The SI gaskets are suitable for ASME B16.5 tongue and groove or male / female (Spigot to Recess) flanges up
Available also for Heat Exchanger applications.Downloads
