-464 BLACK BUNA 70D O-RING

The H70MD464 is an AS568-464 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 17.455 in (443.36 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.005 in (457.33 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against hydraulic fluids, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ozone and direct sunlight or ketones.

The compound is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include automotive, hydraulic and pneumatic systems, and agricultural equipment.
