The H70MD102 is an AS568-102 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 0.049 in (1.24 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.255 in (6.48 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.
Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs and most widely specified general-purpose sealing elastomer. The compound resists propane and butane, many alcohols, and petroleum-based oils. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to automotive brake fluid or polar solvents will shorten service life.
This item is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across construction equipment, general industrial maintenance, and automotive.
