U Cup Seal (Piston-Rod seal):
U Cup Seal is a single acting seal. It is also know as Piston Rod Seal. It is designed to have symmetrical lips in order to be used both in rod and piston applications. This seal is made of PU material. In addition, It has mechanically trimmed lips. Therefore, it creates excellent contact pressure in both dynamic and static one-way sealing. Since it has symmetrical lips, it is applicable in both for rod and piston applications. In addition, it can be used as shaft seal because it has good oil film returning ability. In conclusion, this seal has a good one-way sealing capability for piston and Rod Seal application.

Polyurethane (PU) is a special material that offers the resilience of rubber combined with the toughness and durableness. It allows people to substitute rubber, plastic with PU. Polyurethane can reduce factory maintenance and OEM product cost. Polyurethane has better abrasion and tear resistance than rubbers, and offering higher load bearing capacity.
- Superior static and dynamic sealing effect.
- Wide range of dimensions.
- Easy assembly into closed grooves.
- Simple groove design.
- Economical sealing solution.
- Easy accessible.
Construction machinery, fork lift trucks, injection molding machines, Hydraulic press machines, agricultural machinery, loading platforms and standard cylinders etc.
This seal fits easily in closed grooves as per the sizes. You should use special tools during seal installation. But, the assembly tools must be of soft material and have no sharp edges. Otherwise, the seal might gets damaged. Before installation the wiper must be oiled with system oil.
