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.
Polyurethane
The L-93 polyurethane is a high-performance thermoplastic which properties give hydraulic U-rings (UN, D2 and D3) an excellent resistance to abrasion, friction and wear as well as a low compression set. The use of L-93 polyurethane is recommended with hydraulic oils, mineral oil-based hydraulic fluids, lubricating oils and HFA, HFB-type fluids… On the other hand, gas applications are usually not compatible.
