-336 WHITE BUNA 70D FDA O-RING

H70FDA336 is an AS568-336 white Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 2.85 in (72.39 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.27 in (83.06 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against many alcohols, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where ketones or automotive brake fluid are present.

The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. You will find this material specified across automotive, fluid power, and general industrial maintenance.
