APG stocks the H1.5X29, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 29 mm (1.142 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 32 mm (1.26 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Buna-N (Nitrile) is specified here for low compression set under sustained load and most widely specified general-purpose sealing elastomer. It resists propane and butane, greases and lubricants, and hydraulic fluids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.
Common environments for this compound include agricultural equipment, hydraulic and pneumatic systems, and automotive.
Stocked as H1.5X29 and sold individually. Unit weight is approximately 0.2124 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
