Special
Springlike Metal strips are wound with an Asbestos/Asbestos-Free
P.T.F.E/Grafoil Filler by a special process to assure
a leakproof seal. The sealing is done by the Heat
Resistant Filler and the metal strip provides the
spring. This combination of metal and soft Heat Resistant
Filler piles compresses to its predetermined thickness
under bolting pressure and thereby prevents leakage
within the limit of its specified pressure and temperature.
With the addition of centering devices, "CHAMPION"
Spiral Wound Gaskets can be adapted for use on many
types of flanges and closures.
