-462 BLACK BUNA 70D O-RING

Ordered as H70MD462, this is an AS568-462 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 16.455 in (417.96 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.005 in (431.93 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to many alcohols, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for low compression set under sustained load, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ketones or ozone and direct sunlight.

The compound is metal detectable for HACCP and foreign-body control programs. You will find this material specified across automotive, agricultural equipment, and fluid power.
