-105 BLACK BUNA 50D O-RING

This o-ring is supplied in AS568-105 black Buna-N (Nitrile) 50 Shore A built to an inside diameter of 0.143 in (3.63 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.349 in (8.86 mm), catalogued under part number H50105. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) offers strong abrasion and tear resistance, low compression set under sustained load. It resists propane and butane, petroleum-based oils, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ozone and direct sunlight or ketones will shorten service life.

Maintenance and OEM teams specify it across fluid power, hydraulic and pneumatic systems, and agricultural equipment.

Stocked as H50105 and sold individually. Nominal inside diameter is listed as 5/32 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
