1.5MM CS X 8.5MM ID BLACK BUNA 70D

H1.5X8.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 8.5 mm (0.335 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 11.5 mm (0.45 in). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies. Source specification: Metric O-RING, JIS S9.

It resists hydraulic fluids, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving automotive brake fluid or polar solvents call for a different compound.

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

This item is sold individually under part number H1.5X8.5. Unit weight is approximately 0.0708 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
