-426 BLACK BUNA 70D O-RING

Part number H70426 is an AS568-426 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 4.6 in (116.84 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.15 in (130.81 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to many alcohols, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C).

It sees regular use in general industrial maintenance, construction equipment, and hydraulic and pneumatic systems.

H70426 ships individually. Unit weight is approximately 0.0184 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
