Although there are few industry standards on U-Ring configurations, Zatkoff has established two standard cross-sections to provide a uniform series of seals for

U-Rings, also known as Symmetrical Seals due to their u-shaped profile, are a multi-purpose seal, suitable for either hydraulic or pneumatic rods or pistons. FPE Seals provide a wide range of U-Seals, suitable for many applications. If you require a bespoke item or if you cannot find what you are looking for on our web store please contact us

U-cup Piston-rod seal is a single acting U-symmetric seal. It is designed to have symmetrical lips in order to be used in both for rod and piston applications. Size Chart

The Unloaded U-seals have nothing between the two lips. 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. This assembly is used to block or separate fluid in reciprocating motion applications. Hydraulic seals use is critical in providing a way for fluid

A u-cup is an o-ring formed into a u-shaped channel. Liquid or air pressure "inflates" the u-cup and affects a seal. The u-cup is ideal for use on linear moving shafts and piston heads, because unlike an o-ring the shape does not try to roll with the movement and create friction. The sides of the u-cup allow the shaft to move virtually
