The unloaded urethane U-cup design provides an excellent heavy-duty seal for both piston or rod applications and works well in static and dynamic applications.

A variety of styles, materials and sizes are available to suite your specific requirements.

 

Pressure/Velocity 
Pressure and velocity are two of the factors that will affect seal integrity. The unloaded urethane U-cup is designed to operate between 0 to 250 feet per minute at 1000-3500 psi. However, the unloaded U-cup can operate at up to 900 feet per minute in low or negligible system pressures. The unloaded urethane U-cup’s performance varies depending on temperature, lubrication, and the chemical environment. Performance capabilities can be extended with the use of an anti-extrusion ring.
