-114 BLACK BUNA 90D O-RING

This o-ring is supplied in AS568-114 black Buna-N (Nitrile) 90 Shore A measuring an inside diameter of 0.612 in (15.54 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.818 in (20.78 mm), catalogued under part number H90114. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to propane and butane, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or polar solvents call for a different compound.

You will find this material specified across general industrial maintenance, construction equipment, and hydraulic and pneumatic systems.

Order part number H90114, sold individually. Unit weight is approximately 0.4157 g. Review your operating media and conditions against this specification before installation.
