PAI AN U-Cups are made to the dimensions of Military Drawing AN 6226.
Precision Associates’ Homogeneous Rubber U-Cups are the seal of choice for Pneumatic and low-pressure Hydraulic applications. Because U-Cups do not rely on initial compression to seal, they are excellent in applications that require low breakaway pressure. The sealing lips on Precision Associates’ U-Cups are molded – not cut, so they are always symmetrical. The sealing lip has a very slight radius, reducing the likely hood of wiping all of the lubricant, which might cause a dry surface that leads to wear and early seal failure.
