-271 BLACK BUNA 70D O-RING

Part number H70MD271 is an AS568-271 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 9.234 in (234.54 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.512 in (241.6 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to water, hydraulic fluids, and propane and butane. Buna-N (Nitrile) delivers low compression set under sustained load and an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or strong acids call for a different compound.

The compound is metal detectable for HACCP and foreign-body control programs. You will find this material specified across general industrial maintenance, hydraulic and pneumatic systems, and construction equipment.

H70MD271 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
