  • Fills flaws and irregularities
  • Practically eliminates stem wear
  • Wide range of applications

Key Benefits

  • Easier, faster to install
  • Reduced inventory
  • Longer service life

Technical Specifications

Material: 100% expanded PTFE
Temperature Range: -269°C to +315°C / -452°F to +600°F
Chemical Resistance: Unaffected by most chemicals in the 0-14 pH range except molten alkali metals and elemental fluorine


Pliable and Conformable

Made in a unique process with 100 percent expanded PTFE, GORE Valve Stem Packing offers a high degree of pliability. This allows the packing to conform to worn valve stems and stuffing boxes, eliminating the need for expensive repairs to older valves.

Longer Service Life

GORE Valve Stem Packing has consistently outperformed other packings. Seals made with GORE Valve Stem Packing lasts longer because the unique fibril structure of the material provides better strength, moldability, and conformability. GORE Valve Stem Packing flows into imperfections in both the stem and stuffing box. The softness and self-lubricating nature of GORE Valve Stem Packing practically eliminates stem wear.

Versatility and Performance

GORE Valve Stem Packing will not deteriorate with age, has a low coefficient of friction, and withstands temperatures from -269°C to +315°C / -452°F to +600°F. Moreover, GORE Valve Stem Packing is unaffected by all common chemicals and will not contaminate product flow. It is ideal for use in chemical processing and petroleum refining.
