Part number H2.5X108 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 108 mm (4.252 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 113 mm (4.45 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. This material stands up to greases and lubricants, petroleum-based oils, and hydraulic fluids. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).
Common environments for this compound include construction equipment, general industrial maintenance, and hydraulic and pneumatic systems.
Reference part number H2.5X108 when ordering; the item is sold individually. Unit weight is approximately 2.08 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
