2MM CS X 86MM ID BLACK BUNA 70D

Ordered as H2X86, this is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 86 mm (3.386 in), a cross section of 2 mm (0.079 in), and an outside diameter of 90 mm (3.54 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against water, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

Common environments for this compound include hydraulic and pneumatic systems, construction equipment, and fluid power.

Order part number H2X86, sold individually. Unit weight is approximately 1.08 g. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
