Part number SB-H70126-100 is an AS568-126 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 1.362 in (34.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.568 in (39.83 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies. Source specification: 1.5625IDX1.375"ODX.0938"CS.

Buna-N (Nitrile) is known for strong abrasion and tear resistance, reliable performance in both static and dynamic service. The material holds up against petroleum-based oils, hydraulic fluids, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or automotive brake fluid call for a different compound.

Common environments for this compound include fluid power, construction equipment, and hydraulic and pneumatic systems.

SB-H70126-100 ships by the bag. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
