-023 BLACK BUNA 50D O-RING

Ordered as H50023, this is an AS568-023 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 1.051 in (26.7 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.191 in (30.25 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The material holds up against greases and lubricants, water, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or polar solvents are present.

Maintenance and OEM teams specify it across agricultural equipment, general industrial maintenance, and construction equipment.

Stocked as H50023 and sold individually. Nominal inside diameter is listed as 1 1/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
