APG stocks the H50324, an AS568-324 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 1.35 in (34.29 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.77 in (44.96 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Expect good resistance to water, greases and lubricants, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving strong acids or automotive brake fluid call for a different compound.
Typical settings include construction equipment, fluid power, and automotive.
H50324 ships individually. Nominal inside diameter is listed as 1 3/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
