3.5MM CS X 80MM ID BLACK BUNA 70D

H3.5X80 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 80 mm (3.15 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 87 mm (3.43 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to many alcohols, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ozone and direct sunlight or strong acids.

Typical settings include agricultural equipment, construction equipment, and automotive.
