Pneumatic Seals/U-Packing

Pneumatic homogeneous seals are used to contain pneumatic pressure on a piston and to seal around the rod. Pneumatic homogeneous seals have a low friction coefficient and operate at relatively low pressures. We carry both AN 6226 Airforce Aeronautical Standard, and Series 8400/8500 U-Cup (packing) Note: Some minimums may apply. If you can’t find something you’re looking for, give us a call at 800-445-7803.

8400/8500 Pneumatic U Packing

U-Packings are especially adapted to low speed low pressure situations. The compact configuration of the U-Cup style and its inherent low friction make it an ideal pneumatic seal. If you can’t find something you’re looking for, give us a call at 800-445-7803.
