3MM CS X 33MM ID BLACK BUNA 70D

Part number H3X33 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 33 mm (1.299 in), a cross section of 3 mm (0.118 in), and an outside diameter of 39 mm (1.54 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against petroleum-based oils, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for low compression set under sustained load, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in automotive brake fluid or ozone and direct sunlight.

It sees regular use in agricultural equipment, construction equipment, and general industrial maintenance.
