U-Seal
U-seals or U-cups, are used in rod or piston applications (symmetrical U-seals can be used in either application). The Unloaded U-seals have nothing between the two lips.
These type of parts are relatively soft, non-metallic rings, placed in a groove or fixed in a combination of rings, forming a seal assembly. This assembly is used to block or separate fluid in reciprocating motion applications. Hydraulic seals use is critical in providing a way for fluid power to be converted to linear motion.
Unloaded U-seals come in the following common styles:
- DRU-style Unloaded U-seals
- BS (DRTU-style) Unloaded U-seals
- DPU-style Unloaded U-seals
- DSU-style Unloaded U-seals
- HU-style Unloaded U-seals
- 8400-style Unloaded Symmetrical U-seals (Pneumatics)
