PTFE Valve Stem Packing - 1/8" Round Cross Section - 500 Ft. Spool for Industrial Valves, Pumps, and High-Temperature Sealing Applications

A self-forming packing material made of 100% PTFE. It is a round, expanded product, resulting in a fibrillated, High Tensile Strength material that deforms when compressed to fill all surface irregularities. PTFE Stem Packing is self-lubricating, eliminating stem wear, and is unaffected by most common chemicals. It has an operating temperature range of -450 F to +500 F, contains no contaminants, and is highly resistant to chemical attack. PTFE Valve Stem Packing can be used in a wide variety of applications, including Valves and Faucet stems, rotating shafts, reciprocating plungers, stuffing boxes and flanges. It is also an excellent general purpose gasket material that can be used where a high level of chemical resistance is required.
