Profile KB28 is a single acting /uni-directional U-Cup seal.

Its symmetrical lip design offers the choice of both piston or rod use and the positive shaped lip provides excellent fluid film removal from the mating metal component while providing minimal friction resistance.

Commonly used on both pneumatic and hydraulic actuators it is a good choice for applications where both positive sealing and low friction are required.

KB28 is commonly specified in one of our lubricated PU materials although it is available in many of our high-performance materials and is available for rapid delivery.
