Cantilever Spring Energized PTFE Seal

Spring Energized seal consists of two components, a polymer-base seal jacket and spring.

Cantilever Spring Energized PTFE Seal is consist of a V shaped spring embedded in a polymer jacket.

It has excellent deflection range with linear load curve. Suitable for reciprocating applications.

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.

V Type Spring Features:

Flake opening, small deformation elastic force, but stable elastic force.

Suitable for:

*The shaft of reciprocating mechanism is sealed with the piston.

*Suitable for medium pressure。

*At static, it is easy to adapt to a small deviation of groove size。

*Rotary shaft sealing speed up to 8m/s
