1.5MM CS X 37MM ID BLACK BUNA 70D

APG stocks the H1.5X37, a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 37 mm (1.457 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 40 mm (1.57 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to petroleum-based oils, water, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with ketones or ozone and direct sunlight.

Maintenance and OEM teams specify it across automotive, general industrial maintenance, and hydraulic and pneumatic systems.

Stocked as H1.5X37 and sold individually. Unit weight is approximately 0.0003 g. Check the compound against your process media, pressure and temperature before committing to a design.
