U-cup

Face seal used for rotary and oscillating motion in pipe joints and rotary actuators

The MANOY® U‑Cup is a pressureactivated sealing system. This means that the total sealing force is only ever as high as required to seal the prevailing pressure. This friction optimization saves energy.The MANOY® U‑Cup seals gases and liquids and also highviscosity fluids and pastes in a nonstandard version

Suitable for nearly all fluids, Dry running possible, Low coefficient of friction, Very long life due to high abrasion resistance, No stickslip at low speed, Does not stick to the mating surface after prolonged shutdown, Nonsensitive to pressure peaks, Available in any diameter up to 700 mm
