Style 625 gaskets were originally designed by Flexitallic for clamp type closures in aircraft, but are now widely used wherever space limitations indicate the need for a wafer-thin or narrow spiral wound gasket.
The spiral wound gaskets are similar to style R 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.
