-454 BLACK BUNA 70D O-RING

APG stocks the H70454, an AS568-454 black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 12.475 in (316.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 13.025 in (330.84 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against petroleum-based oils, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or automotive brake fluid are present.

You will find this material specified across hydraulic and pneumatic systems, agricultural equipment, and construction equipment.

Stocked as H70454 and sold individually. Unit weight is approximately 47.05 g and nominal inside diameter is listed as 12 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
