-241 BLACK BUNA 90D O-RING

The H90241 is an AS568-241 black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 3.859 in (98.02 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.137 in (105.08 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to hydraulic fluids, petroleum-based oils, and water. Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving ketones or strong acids call for a different compound.

Maintenance and OEM teams specify it across general industrial maintenance, agricultural equipment, and hydraulic and pneumatic systems.
