2.65MM CS X 30MM ID BLACK BUNA 70D

Part number H2.65X30 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 30 mm (1.181 in), a cross section of 2.65 mm (0.104 in), and an outside diameter of 35.3 mm (1.39 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is widely chosen for low compression set under sustained load, strong abrasion and tear resistance. Expect good resistance to petroleum-based oils, greases and lubricants, and propane and butane. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or ozone and direct sunlight will shorten service life.

Maintenance and OEM teams specify it across automotive, construction equipment, and hydraulic and pneumatic systems.

H2.65X30 ships individually. Unit weight is approximately 0.7 g. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
