-102 BLACK BUNA 70D O-RING

APG stocks the H70102, an AS568-102 black Buna-N (Nitrile) 70 Shore A O-Ring with 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). An o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists water, hydraulic fluids, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or ozone and direct sunlight will shorten service life.

Common environments for this compound include general industrial maintenance, agricultural equipment, and hydraulic and pneumatic systems.

Reference part number H70102 when ordering; the item is sold individually. Unit weight is approximately 0.0818 g and nominal inside diameter is listed as 1/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
