-910 BLACK BUNA 90D O-RING

The H90910 is an AS568-910 black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 0.755 in (19.18 mm), a cross section of 0.097 in (2.46 mm), and an outside diameter of 0.949 in (24.1 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, low compression set under sustained load. The compound resists many alcohols, hydraulic fluids, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or polar solvents are present.

Typical settings include fluid power, construction equipment, and automotive.
