3.5MM CS X 22.1MM ID BLACK BUNA 90D

APG stocks the H90M3.5X22.1, a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 22.1 mm (0.87 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 29.1 mm (1.15 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 P22.4.

This material stands up to petroleum-based oils, greases and lubricants, and water. That behavior comes from the compound itself: Buna-N (Nitrile) delivers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or automotive brake fluid are present.

You will find this material specified across hydraulic and pneumatic systems, fluid power, and agricultural equipment.

H90M3.5X22.1 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
