Leader Spiral Wound Gaskets

LeaderDesigned more than 100 years ago, Spiral Wound Gaskets (SWGs) 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, SWGs offer high compressibility and recovery. 

Typical applications for these types of gaskets: (Petro-) Chemical Industry, Steam, On- and Offshore exploration, pipeline systems, pressure vessels and exchangers. Spiral Wound Gaskets can be used in a wide variety of media, for example pH ranges varying from 0 - 14.

Temperature range for all products on this page is: -450°F to 850°F (steam up to 1200°F)

Gaskets can be manufactured in a thickness of .125" / .175" / .250" / 285".
