2.7MM CS X 16.9MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 16.9 mm (0.665 in), a cross section of 2.7 mm (0.106 in), and an outside diameter of 22.3 mm (0.88 in), catalogued under part number H2.7X16.9. It remains the most cost-effective sealing element available for pressurized assemblies.

It resists propane and butane, many alcohols, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with polar solvents or strong acids.

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

This item is sold individually under part number H2.7X16.9. Application requirements vary, so validate compatibility with your process conditions prior to installation.
