U-Rings, the seal with the widest range of uses

The U-Ring is a multipurpose seal that can be fitted either on a rod or on a piston. The U-Rings have high sealing properties and excellent resistance to abrasion, friction and wear. Its use is recommended with hydraulic oils, mineral oil-based hydraulic fluids, lubrication oils and HFA, HFB fluids…

U-Rings are manufactured in L-93 polyurethane, an extremely high-performance thermoplastic which guarantees seals with low permanent deformation.

This seal features many benefits, among which we can highlight the simple method of assembly and disassembly and excellent resistance to wear. Pneumatic and hydraulic cylinders, presses and lifts comprise their main fields of use.

We have provided more information on these seals if you wish to learn more about them. And, of course, not forgetting you can request an estimate or purchase from our online store, available 24 hours a day.
