1.8MM CS X 6MM ID BLACK BUNA 70D

The H1.8X6 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 6 mm (0.236 in), a cross section of 1.8 mm (0.071 in), and an outside diameter of 9.6 mm (0.38 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to propane and butane, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) offers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. 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 agricultural equipment, construction equipment, and hydraulic and pneumatic systems.

This item is sold individually under part number H1.8X6. Unit weight is approximately 0.077 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
