-170 BLACK BUNA 50D O-RING

The H50170 is an AS568-170 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 7.737 in (196.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.943 in (201.75 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The material holds up against water, greases and lubricants, and propane and butane. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or automotive brake fluid will shorten service life.

It sees regular use in automotive, fluid power, and agricultural equipment.
