Style 625 spiral wound gaskets are similar to Style R spiral wound gaskets, except original thickness is 0.0625″. These gaskets are widely used wherever space restrictions indicate the need for a wafer thin gasket design capable of sealing high pressures. Style 625 spiral wound gaskets embody all of the exclusive features for keeping compression values in balance with bolting and providing correct resiliency to compensate for variable stresses encountered in service.
Style 625 spiral wound gaskets are manufactured to a nominal thickness of .0625″, with compression to .050″ – .055″.
Style 625 was originally designed for clamp-type closures in aircraft, but are now widely used whenever space limitations indicate the need for a wafer-thin or narrow spiral wound gasket.
