  • DSH-Spring O Ring, Ptb-custom Spring Energized Ptfe Seal
Product Details
DSH Seals pursues perfection in every detail of oil seal, so as to show quality excellence. oil seal has passed the quality inspection of the national authority. It is a high-quality and performance-stable product that customers can purchase with confidence.
  • DSH-Spring O Ring, Ptb-custom Spring Energized Ptfe Seal
Company Advantages
1. DSH variseal is manufactured using state-of-the-art technology to guarantee the fine workmanship and smooth production. There is no chemical swell when it is subjected to moisture or fluids
2. Featuring spring loaded seal, spring seal is recognized by customers. It does not harden or become brittle at low temperatures
3. We have developed various complete divisions to ensure the quality such as spring energized seal design and spring loaded double lip seal. It will not stick to the metal surface


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.
