Product Description

Product description
PTFE Piston combination seal/hydraulic seal for Excavator by a rubber o-rings and ptfe ring combination. O-rings, applying to lap is a double-acting piston seal. The friction is low, no creeping,  Start-up force is small, resistance to high pressure.

Feature
To circle is usually made from synthetic rubber qualitative protection ring and superposition of filled ptfe qualitative square seals use, it can be divided into the hole and shaft used to use to circle, but its sealing function is the same, in accordance with its own initial deformation on the sealing surface of high contact stress, prevent leakage of pressure of the liquid. Hydraulic cylinder, pressure of liquid by elastic ring in the maximum extrusion rectangular sealing ring, make it close to the sealing surfaces, resulting in increased with the pressure of the liquid pressure of higher and higher additional contact stress, contact stress and the initial together to prevent leakage of liquid pressure.

The purpose
used in reciprocating motion high-pressure oil cylinder piston seal, o-rings and combination

Application Range.
