Application
The IUH rod seal is used as a primary seal for hydraulic cylinder piston rods to help prevent hydraulic oil leakage in reciprocating applications.
This profile is intended for reciprocating hydraulic cylinder rod-sealing applications. Confirm the equipment model, operating medium, pressure, temperature, and groove design before selection.
Installation and Design Notes
Confirm the IUH profile drawing, rod surface condition, edge radii, extrusion gap, and groove dimensions before installation. The suitable NBR or HNBR material should be selected according to the actual temperature, pressure, hydraulic medium, and service environment.
