800 Rod

A patented seal designed specifically for hydraulic swivels. Manufactured in the high grade Hythane® 181, Hallite’s Ro800 is engineered as a one piece seal. No relative motion between the seal and the energiser can effect the lifetime of this seal, which is often mainly the problem of two piece swivel seals.

The special design of the Ro800 is minimizing the friction.

Optional anti-extrusion rings made from acetal are allowing larger extrusion gaps. The seal without anti-extrusion rings are made for applications with a very good guidance or low working pressure. Therefore please contact our technical service.

Ro800 is designed for double acting conditions. Designs are available for piston or rod applications.

The seal is easy to install in one piece housings.

Part numbers ending 00 are without anti-extrusion rings.
