4.5MM CS X 86MM ID BLACK BUNA 70D

H4.5X86 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 86 mm (3.386 in), a cross section of 4.5 mm (0.177 in), and an outside diameter of 95 mm (3.74 in). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. It resists propane and butane, petroleum-based oils, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life.

Typical settings include fluid power, agricultural equipment, and construction equipment.
