1.3MM CS X 11MM ID BLACK BUNA 70D

Part number H1.3X11 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 11 mm (0.433 in), a cross section of 1.3 mm (0.051 in), and an outside diameter of 13.6 mm (0.54 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists petroleum-based oils, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

Maintenance and OEM teams specify it across fluid power, hydraulic and pneumatic systems, and automotive.
