6226 STYLE HOMOGENIOUS U CUP

This u-cup seal is supplied in Buna-N (Nitrile) built to a 3/4 inch inside diameter, a 1-1/4 inch outside diameter, and a height of 1/4 inch, catalogued under part number NU6226-16. It delivers pressure-energized single-acting sealing on rods and pistons.

Expect good resistance to water, hydraulic fluids, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Applications involving automotive brake fluid or ketones call for a different compound.

Maintenance and OEM teams specify it across agricultural equipment, fluid power, and hydraulic and pneumatic systems.

Stocked as NU6226-16 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
