5MM CS X 108MM ID BLACK BUNA 70D

Ordered as H5X108, this is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 108 mm (4.252 in), a cross section of 5 mm (0.197 in), and an outside diameter of 118 mm (4.65 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to propane and butane, hydraulic fluids, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer and low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).

You will find this material specified across construction equipment, hydraulic and pneumatic systems, and agricultural equipment.
