-137 BLACK BUNA 70D O-RING

APG stocks the H70137, an AS568-137 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 2.05 in (52.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.256 in (57.3 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. The material holds up against hydraulic fluids, many alcohols, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

You will find this material specified across automotive, hydraulic and pneumatic systems, and agricultural equipment.

H70137 ships individually. Unit weight is approximately 0.0012 g and nominal inside diameter is listed as 2 1/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
