Valve Stem PackingThis easily molded product is designed to compress within a threadless space to form an impenetrable seal in faucets, valves, plungers, and shafts. SealPak can also be wound between flanges to form a waterproof, chemically inert seal in place of rubber gaskets.
Valve stem packing is used to eliminate stem wear and fill irregular surfaces, providing excellent general-purpose sealing. Made of the same ultra-high quality, 100% virgin PTFE film as our traditional high-performing tapes, SealPak is unaffected by most chemicals and is safe for operation between -450 and 550 degrees Fahrenheit.
