2.7MM CS X 13.6MM ID BLACK BUNA 70D

Ordered as H2.7X13.6, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 13.6 mm (0.535 in), a cross section of 2.7 mm (0.106 in), and an outside diameter of 19 mm (0.75 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists petroleum-based oils, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is known for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or ozone and direct sunlight will shorten service life.

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