-314 BLACK BUNA 70D O-RING

Part number H70MD314 is an AS568-314 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 0.725 in (18.42 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.145 in (29.08 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists greases and lubricants, many alcohols, and water. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving ozone and direct sunlight or polar solvents call for a different compound.

This o-ring is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include fluid power, construction equipment, and agricultural equipment.

H70MD314 ships individually. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
