PTB Spring Energized PTFE Seals make use of a V shaped spring embedded in a polymer jacket. At installation, the V shape of the spring is compressed, providing sealing energy to the seal jacket ensuring a positive seal. With a linear load curve and excellent deflection range, PTB Spring Energized PTFE Seals are a very versatile product. They are common replacements when rubber u-cups fail due to chemical attack, extreme temperature range, friction concerns and wear issues. Cantilever Spring Seals are best suited for reciprocating applications such as shocks, hydraulic cylinders, pumps and compressors. The shape of the spring concentrates load on the front of the seal, which makes this design also suitable for use as environmental excluders and for applications requiring scraping of viscous media. As an additional option, the spring cavity area can be filled with silicone for FDA clean-in-place applications. 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 PTB spring energized PTFE Seal piston products are carbon fiber, fiberglass, aromatic polyester and graphite. Virgin PTFE is also popular for these products when conditions are mild.
