Product Specification

-
APG stocks the H90M4X44, a black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 44 mm (1.732 in), a cross section of 4 mm (0.157 in), and an outside diameter of 52 mm (2.05 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. It resists greases and lubricants, water, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving ozone and direct sunlight or polar solvents call for a different compound.

Common environments for this compound include automotive, construction equipment, and fluid power.
