DESCRIPTION

The UA-6226 Style U-seals have a square format where the nominal cross section is equal to the height. Although widely used in the fluid power industry for low friction pneumatics, this profile was originally designed for early aircraft and ordinance service. Many units still use this type U-seals. The u-seal numbers conform in size to Army-Navy specification AN6226.

Also available in Fluorocarbon for a wide range of chemical media and temperatures up to 400F
