The design configurations are identified as follows.
U cup seal design.
Larger than the groove for which it is intended.
Spring energized u cups spring energized u cups are engineered plastic seals that incorporate a metallic spring.
Fluid power seals sizes readily available in a multitude of materials to provide optimal compatibility with the various hydraulic fluids encountered in service.
Rated for pressure up to 10 000 psi these leather u cups handle over 80 times more pressure than our buna n u cups.
U cup seals or u ring seals are commonly used in linear applications to seal the rod or piston.
Homogenous u cups homogenous u cups are popular in low pressure applications where a low friction seal would be beneficial.
U cup is a specialized rod seal design developed from the standard symmetrical u cup.
It assures improved sealing performance due to the following features.
O ring loaded u cup seals also known as loaded lip seals and polypaks an o ring secures these u cups to the rod or piston for better sealing performance at lower pressures than unsupported u cup seals.
The o ring store offers an assortment includes rod piston and wiper seals as well as guides o rings and back up rings.
U cups seals symmetrical design.
The spring loads the seal s lips against the mating hardware creating a seal capable of compensating for movement in dynamic applications.
Many different u cup configurations exist to properly seal that demanding application.
Parker s 8400 profile u cup is a light load symmetrical lip seal for use in either rod or piston sealing applications.
Loaded u seals or u cups sometimes called polypaks are loaded with an o ring or sometimes a quad ring between the two lips to increase the sealing force at low pressures.
Rated for pressure up to 10 000 psi these leather u cups handle over 80 times more pressure than our buna n u cups.
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.
U cup has an od.
The unloaded urethane u cup is commonly known as a disogrin u cup.
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.
O ring loaded u cup seals also known as loaded lip seals and polypaks an o ring secures these u cups to the rod or piston for better sealing performance at lower pressures than unsupported u cup seals.
This insures a tight fit in the groove to prevent movement of the seal during.
The fourth part of the numbering system identifies the specific seal design configuration required.
Hydraulic sealing solutions for fluid power applications have become a priority in our continued product offering.
U cup seal design these type of parts are relatively soft non metallic rings placed in a groove or fixed in a combination of rings forming a seal assembly.
