3.6MM CS X 35.6MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A with an inside diameter of 35.6 mm (1.402 in), a cross section of 3.6 mm (0.142 in), and an outside diameter of 42.8 mm (1.69 in), catalogued under part number H3.6X35.6. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to many alcohols, hydraulic fluids, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving automotive brake fluid or ketones call for a different compound.

You will find this material specified across fluid power, construction equipment, and automotive.

Reference part number H3.6X35.6 when ordering; the item is sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
