2MM CS X 42MM ID BLACK BUNA 90D

The H90M2X42 is a black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 42 mm (1.654 in), a cross section of 2 mm (0.079 in), and an outside diameter of 46 mm (1.81 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to propane and butane, water, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or ozone and direct sunlight.

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