B-type loaded U-cup hydraulic seals are used for dynamic reciprocating applications. Sometimes called loaded-lip U-cups, B-style polypack, and lip seals, these seals have a beveled edge with a symmetrical cross section. They have a quad-ring loader that makes the seal a good choice for low-pressure rod applications. The sealing force compensates for high-pressure to maintain a positive seal.
Rod seal kits include a rod assembly, rod wiper seal, U-cup rod seal, and O-ring for repairing hydraulic cylinders.
