APG stocks the H70MD154, an AS568-154 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 3.737 in (94.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.943 in (100.15 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, reliable performance in both static and dynamic service. The material holds up against many alcohols, hydraulic fluids, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life.
This o-ring is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across automotive, fluid power, and construction equipment.
Stocked as H70MD154 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
