-148 BLACK BUNA 90D O-RING

APG stocks the H90148, an AS568-148 black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 2.737 in (69.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.943 in (74.75 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. This material stands up to hydraulic fluids, greases and lubricants, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to strong acids or ozone and direct sunlight will shorten service life.

Typical settings include construction equipment, fluid power, and hydraulic and pneumatic systems.
