4.5MM CS X 26MM ID BLACK BUNA 70D

APG stocks the H4.5X26, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 26 mm (1.024 in), a cross section of 4.5 mm (0.177 in), and an outside diameter of 35 mm (1.38 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, economical choice for high-volume maintenance programs. It resists hydraulic fluids, greases and lubricants, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in polar solvents or ketones.

You will find this material specified across general industrial maintenance, automotive, and agricultural equipment.

Stocked as H4.5X26 and sold individually. 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.
