The Hose & More Store's Expanded PTFE Stem Packing is an all purpose, 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 -450ºF to +500ºF, contains no contaminants, and is highly resistant to chemical attack.

 Our 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.

Form-In-Place - conforms to stuffing box and surface irregularities such as scratches, pits
or otherwise imperfect surfaces

Flexible – can be installed on small stems or shafts without splitting.

Chemically Resistant – made without fillers or binders, our 100% PTFE Stem Packing exhibits the same chemical inertness of pure virgin PTFE.

Our Expanded PTFE Valve Stem Packing has an Unlimited Shelf Life and shows No Age Deterioration.
