Product Description

Product Description

Description

PTFE MDD series is a rubber energized plastic faced seal, designed to expand and significantly improve the service parameters of O-Rings. MDD series can be installed in existing O-Ring grooves. 
MDD series combines the flexibility and responsiveness of O-Rings with the wear and friction characteristics of the PTFE materials in dynamic applications.

The double-acting performance of the seal follows from the symmetrical cross section which allows the seal to respond to pressure in both directions.

Initial contact pressure is provided by radial compression of the O-Ring. When the system pressure is increased the O-Ring transforms this into additional contact pressure, the contact pressure of the seal is thereby automatically adjusted so sealing is ensured under all service conditions.

Pressure:	Up to 35 MPa
Speed:	Up to 15 m/s
Material:	PTFE(PU)+NBR\FKM
Temperature:	-45 °C to +200 °C
