-124 BLACK BUNA 70D O-RING

Part number H70MD124 is an AS568-124 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 1.237 in (31.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.443 in (36.65 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) is widely chosen for low compression set under sustained load and an economical choice for high-volume maintenance programs. The compound resists many alcohols, petroleum-based oils, and greases and lubricants. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving polar solvents or strong acids call for a different compound.

This o-ring is metal detectable for HACCP and foreign-body control programs. It sees regular use in general industrial maintenance, agricultural equipment, and construction equipment.
