8MM CS X 342MM ID BLACK BUNA 70D

Ordered as H8X342, this is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 342 mm (13.465 in), a cross section of 8 mm (0.315 in), and an outside diameter of 358 mm (14.09 in). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. This material stands up to hydraulic fluids, petroleum-based oils, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with ozone and direct sunlight or strong acids.

Maintenance and OEM teams specify it across general industrial maintenance, construction equipment, and automotive.

H8X342 ships individually. Review your operating media and conditions against this specification before installation.
