1MM CS X 12.5MM ID BLACK BUNA 90D

Part number H90M1X12.5 is a black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 12.5 mm (0.492 in), a cross section of 1 mm (0.039 in), and an outside diameter of 14.5 mm (0.57 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for low compression set under sustained load, reliable performance in both static and dynamic service. This material stands up to hydraulic fluids, greases and lubricants, and petroleum-based oils. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or automotive brake fluid call for a different compound.

Common environments for this compound include general industrial maintenance, agricultural equipment, and fluid power.

H90M1X12.5 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
