3MM CS X 22MM ID BLACK BUNA 90D

Part number H90M3X22 is a black Buna-N (Nitrile) 90 Shore A O-Ring with an inside diameter of 22 mm (0.866 in), a cross section of 3 mm (0.118 in), and an outside diameter of 28 mm (1.1 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as Metric O-RING, JIS G22.

The material holds up against propane and butane, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ozone and direct sunlight or automotive brake fluid.

Maintenance and OEM teams specify it across construction equipment, fluid power, and agricultural equipment.
