2.5MM CS X 37MM ID BLACK BUNA 70D

Ordered as H2.5X37, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 37 mm (1.457 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 42 mm (1.65 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to hydraulic fluids, propane and butane, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ozone and direct sunlight or polar solvents.

Common environments for this compound include agricultural equipment, general industrial maintenance, and automotive.

H2.5X37 ships individually. Unit weight is approximately 0.7457 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
