Product Description

Description

Description

RDD is a rubber energized plastic 
faced seal, designed to expand and significantly 
improve the service parameters of O-Rings. Double 
RDD can be installed in existing O-Ring grooves.

RDD combines the flexibility and responsiveness of O-Rings with the wear and friction characteristics of the 
Our 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.

Notch and Advantages

NOTCH

Advantages

RDD is as standard supplied without radial notches, 
as the thin radial section of the seal gives good response to 
pressure variations. 
For diameters from 2 mm, notches on both sides are optional. 
These ensure direct pressurizing of the seal under all operating 
conditions.

- Compact groove dimensions and simple installation 
- Low friction without stick-slip 
- Resistance against wear and extrusion 
- Rod seals available for all diameters from 2 to 999.9 mm 
- Standard cross sections cover AS 568A and important 
metric O-Rings, other cross sections available on request. 
- Fits also groove dimensions per ISO 6194 and AS 4716
