PTA Spring Energized Seals are comprised of a wound ribbon metal spring installed in a polymer jacket. This helical shape spring affords a relatively high load versus deflection range resulting in a sealed product that can provide very tight sealing. As a highly loaded product, PTA Spring Seals should be considered when dynamics are very slow or static. Examples are in stems seals and in cryogenic valves where additional force is required to overcome thermal effects.

The seals always seem to gravitate toward certain difficult applications which include:

  • Harsh chemicals and solvents.
  • High temperatures up to 260℃.
  • Cryogenic temperatures down to -40℃.
  • Unlubricated applications.
  • Where low friction is required.
  • High pressures up to 450bar.
  • High surface speeds when other seals overheat
  • The most popular PTFE fillers used for PTA spring energized PTFE Seal rod
    products are carbon fiber, fiberglass, aromatic polyester and graphite. Virgin PTFE is also popular for these
    products when conditions are mild.
