Leader Spiral Wound Gasket Type SR

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. Due to the gasket construction, SWG’s offer high compressibility and recovery. Leader Style SR SWG’s are provided with an outer guide ring. The SR gaskets are suitable for ASME B16.5 raised faced flanges up to 600lbs and for EN/DIN flanges up to PN40. We strongly recommend to use SRI gaskets with inner guide ring in all circumstances.
