H50206 is an AS568-206 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 0.484 in (12.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.762 in (19.35 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.
Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, economical choice for high-volume maintenance programs. The material holds up against hydraulic fluids, petroleum-based oils, and greases and lubricants. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or strong acids will shorten service life.
Maintenance and OEM teams specify it across construction equipment, agricultural equipment, and general industrial maintenance.
H50206 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
