-366 BLACK BUNA 50D O-RING

APG stocks the H50366, an AS568-366 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 7.225 in (183.52 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.645 in (194.18 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, low compression set under sustained load. It resists propane and butane, greases and lubricants, and water. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or ozone and direct sunlight are present.

Typical settings include construction equipment, general industrial maintenance, and fluid power.

H50366 ships individually. Nominal inside diameter is listed as 7 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
