2.5MM CS X 44MM ID BLACK BUNA 70D

The H2.5X44 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 44 mm (1.732 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 49 mm (1.93 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Buna-N (Nitrile) is widely chosen for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. It resists hydraulic fluids, water, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ozone and direct sunlight or strong acids.

Common environments for this compound include construction equipment, automotive, and fluid power.
