Description :

UBE is designed for use as a single acting piston seal.

The seal is a precision moulded Nitrile rubber sealing element with a bonded reinforced fabric base and an acetal back up ring to resist extrusion.

The acetal back up ring allows larger clearances and higher pressures.

The seal is designed with initial radial interference to effect low pressure sealing.
At higher pressures the seal is energised thus increasing sealing .

The rubberised fabric header has the advantage of
retaining fluid within its surface thus reducing both friction and wear.

PRODUCT ADVANTAGES :

• Superior static and dynamic sealing effect
• Improved sealing gap due to the active back-up ring
• Relief grooves against dynamic pressure
• Highly wear resistant

APPLICATION :

Heavy duty cylinders, scrap cutters and hydraulic jacks.
