The H2X30.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 30.5 mm (1.201 in), a cross section of 2 mm (0.079 in), and an outside diameter of 34.5 mm (1.36 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, Buna-N (Nitrile) is valued for low compression set under sustained load, strong abrasion and tear resistance. Expect good resistance to greases and lubricants, many alcohols, and water. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with automotive brake fluid or ozone and direct sunlight.
It sees regular use in fluid power, general industrial maintenance, and construction equipment.
