Name:PTFE self-lubrication hydraulic cylinder seals ID:005 
PTFE cylinder oil seals are the oil seals that dressing PTFE sheet on the surface of ordinary Y-ring and O-ring. So the seals have the low frictional factor 0.05 with the cylinder. These seals have stable, reliable and enduring stopping properties. |

Structure-A
This structure of Y-ring is recombined the PTFE with rubber elastomer on the frictional surface.
Be applicable for: high temperature, wear resistant oil cylinder sealing.
The structure of Y-ring can differ in accordance with the different working conditions. Our company are willing to design and manufacture as per operating mode. The following structures are applicable to bulldozer, excavator and other engineering machinery. |

Structure-B
Structure-B consists of PTFE strips and O-rings. Using the O-ring can keep the strips close to the inner surface of the cylinder, or to the surface of piston rod.

Structure-C
Type-C mainly function though Type-B O-ring. The O-ring’s rubber elastomer can be FKM, FPM, MVQ, NBR, or CR, etc, in accordance with different operating mode. Recombining PTFE sheet (from 0.15 to 0.45mm) with the rubber elastomer ,the O-ring have self-lubricity. Scope of application: medium or low pressure, high frequency reciprocating movement.
