Product Description

Product Description

Description

 WDD is a rubber energized plastic faced seal, designed to expand and significantly improve the service parameters of O-Rings. It can be installed in existing O-Ring grooves.MDD combines the flexibility and responsiveness of O-Rings with the wear and frictioncharacteristics of the 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.
 
 
 
ADVANTAGES  
--Compact groove dimensions and simple installation
-- Low friction without stick-slip
 --Resistance against wear and extrusion
-- Piston seals available for all diameters 
from 5 to 999.9 mm
- -Standard cross section cover AS 568A and important metric 
O-Rings, other cross sections available on request.
 Fits also groove dimensions per ISO 6194 and AS 4716
 
 
APPLICATION EXAMPLES
--Machine tools
--Handling devices
 --Valves
 --Chemical process equipment
 It is particular recommended for light duty and small diameter 
applications.
