2MM CS X 7MM ID BLACK BUNA 70D

Ordered as H2X7, this is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 7 mm (0.276 in), a cross section of 2 mm (0.079 in), and an outside diameter of 11 mm (0.43 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists water, hydraulic fluids, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with polar solvents or strong acids.

Common environments for this compound include automotive, general industrial maintenance, and construction equipment.

Stocked as H2X7 and sold individually. Unit weight is approximately 0.1127 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
