6226 STYLE HOMOGENIOUS U CUP

Part number NU6226-3 is a Buna-N (Nitrile) U-Cup U-Cup Seal supplied with a 1/4 inch inside diameter, a 5/8 inch outside diameter, and a height of 3/16 inch. An u-cup seal delivers pressure-energized single-acting sealing on rods and pistons.

The compound resists petroleum-based oils, many alcohols, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for low compression set under sustained load and an economical choice for high-volume maintenance programs.

Maintenance and OEM teams specify it across construction equipment, automotive, and agricultural equipment.

This item is sold individually under part number NU6226-3. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
