More about the U-ring seal The inside of the U-Seal is a dynamic lip seal that is used for when there is motion between surfaces. The ?U? shape energizes the sealing lips as the application pressure increases. The primary reason for the existence of U-rings is its interchangeability between rod and piston applications.

cup is an oring formed into a ushaped channel. Liquid or air pressure ?inflates? the ucup and affects a seal. The ucup is ideal for use on linear moving shafts and piston heads, because unlike an oring the shape does not try to roll with the movement and create friction.

Loaded U-cups: These are loaded with an O-ring which helps tight sealing at low pressures. Unloaded U-cups: These are without O-rings and are suitable for heavy-duty sealing applications. Spring Energized U-cups: These specially engineered U-cups comprise a metallic spring in place of the O-ring.

The unique combination of resilience and its resistance to gap extrusion and wear makes thermoplastic polyurethane (TPU) the most common material used for U-cup seals in hydraulic applications. They are available with a single- or double-lip design.

They come in two designs, unloaded or loaded. Unloaded simply means is does not have an O-Ring inside. The loaded U-Cup, also known as a Polypak, has an O-Ring or sometimes a quad ring within the seal to act as an expander to provide even better sealing capabilities.

cups are a lip seal, named for the crosssection's distinctive "" shape. They are used for both dynamic and static applications. The "" shape energizes the sealing lips as the application pressure increases. This brilliant design has been modified to create several unique configurations.

U Cup seals, as their name implies, have a U-shaped profile, including an outside static sealing lip and an inside dynamic sealing lip. U-Cups, or U-Seals are used for both dynamic and static applications. The ?U? shape energizes the sealing lips as the application pressure increases.
