Heel of the u cup.
U cup seal groove design.
The seal is most commonly used in pneumatic applications as a rod or piston seal.
The hu seal is popular in low pressure applications where a low friction seal would be beneficial.
Hydraulic sealing solutions for fluid power applications have become a priority in our continued product offering.
U cup is a specialized piston seal design.
The seal design and the polyurethane properties give efficient fluid sealing reduced friction values and low wear rate.
Homogenous u cups block vees are a non loaded single material u cup.
The o ring store offers an assortment includes rod piston and wiper seals as well as guides o rings and back up rings.
An o ring secures them to the rod or piston preventing leaks at low pressure and as the seal wears.
U cup has an id smaller than the groove for which it is intended.
The thin flexible lip design reacts to low pressure and provides an extremely smooth steady movement with less break away force required because of the inherent low friction.
It assures improved sealing performance due to the following features.
Groove depth refers to the axial dimension of the seal gland and adequate space is required for the o ring loaded u cup to perform properly.
Parker s 8400 profile u cup is a light load symmetrical lip seal for use in either rod or piston sealing applications.
The sealing effect of a u cup symmetric seal is obtained thanks to the lip pre compression due to installation and to the pressure effect on the lips.
Developed from the standard symmetrical u cup.
Squeeze in this area would result in an extremely high loading of the sealing lips and can result in increased friction heat seal wear and likely premature seal failure.
The design is suited for situations where space is limited.
These seals are suitable for closed groove installation.
Fluid power seals sizes readily available in a multitude of materials to provide optimal compatibility with the various hydraulic fluids encountered in service.
These u cup seals create less friction than o ring loaded u cups so they wear more slowly also known as lip seals u cups have a sealing lip on both the inside and outside edges so they can be used for rod and piston sealing.
