Designed more than 100 years ago, Spiral Wound Gaskets
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. The standard metallic material used for
winding is SS316L, while the soft filler consists of graphite,
PTFE, or LeaderTherm NXT 1000 (a high-temperature
modified Phlogopite). Due to the gasket’s construction, SWGs offer high compressibility and recovery. Leader Style S SWGs are provided with a sealing element only. The S gaskets are suitable for ASME B16.5 tongue and groove or male/female (Spigot to Recess) flanges up to 2500 Class. They are primarily used in pumps and valves.
Petrochemical Industry, Steam, On and Offshore Exploration, Pipeline Systems, Pressure Vessels and Exchangers.
Subject to materials, Spiral Wound Gaskets can be used in a wide variety of media, with a pH range varying from 0-14. Application/Compatibility Guide is available on request.
Standard style S gaskets are normally manufactured according to particular customer drawings, or by given sizes. Gaskets can be manufactured in a thickness of .125″ / .175″ / .250″ / 285″.
