2MM CS X 185MM ID BLACK BUNA 70D

Part number H2X185 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 185 mm (7.283 in), a cross section of 2 mm (0.079 in), and an outside diameter of 189 mm (7.44 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to many alcohols, water, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in polar solvents or strong acids.

Maintenance and OEM teams specify it across hydraulic and pneumatic systems, agricultural equipment, and general industrial maintenance.

This item is sold individually under part number H2X185. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
