2.5MM CS X 48MM ID BLACK BUNA 70D

The H2.5X48 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 48 mm (1.89 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 53 mm (2.09 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists propane and butane, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or polar solvents are present.

Typical settings include fluid power, agricultural equipment, and construction equipment.

H2.5X48 ships individually. Unit weight is approximately 0.98 g. Check the compound against your process media, pressure and temperature before committing to a design.
