-202 BLACK BUNA 90D O-RING

This o-ring is supplied in AS568-202 black Buna-N (Nitrile) 90 Shore A measuring an inside diameter of 0.234 in (5.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.512 in (13 mm), catalogued under part number H90202. It remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against hydraulic fluids, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with ozone and direct sunlight or polar solvents.

Maintenance and OEM teams specify it across construction equipment, automotive, and general industrial maintenance.

Stocked as H90202 and sold individually. Unit weight is approximately 0.378 g and nominal inside diameter is listed as 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
