Symmetrical U-cups

For rod and piston

U-cup seals as their name implies, have a U-shaped profile with an inside and outside sealing lip. Symmetrical u-cups have an equal length inside and outside sealing lips which allows these seals to be used as either a rod seal or a single acting piston seal. Using two u-cups in opposing direction on a piston allows the cylinder to be double acting.

Their resilience to gap extrusion and wear makes thermoplastic polyurethane (TPU) the most common material used for u-cup seals in hydraulic applications. Some u-cup seals are energised, which means the sealing lips are preloaded by a rubber o-ring or quad ring that provides additional sealing force and improves the long-term resilience of the sealing lips. Energised seals can also be beneficial in applications with low operating pressures (e.g. pneumatic applications) and low temperatures.

STD: Imperial Symmetrical U-cup

STD rod and piston seals are made of TPU and are suitable for pressures up to 400 bar (5,800 psi) and can also be used as a heavy duty static seal or snap-in rod wiper. STD u-cups are available in imperial sizes.

PTB: Imperial Symmetrical U-cup

PTB rod and piston seals are made of TPU and are suitable for pressures up to 400 bar (5,800 psi). Its type-B back-bevel sealing lip design with a chamfer on the leading edge regulates the fluid film on the piston rod surface and also mitigates damage to the seal during installation. PTB u-cups are available in imperial sizes.
