5.7MM CS X 94.1MM ID BLACK BUNA 90D

Part number H90M5.7X94.1 is a black Buna-N (Nitrile) 90 Shore A O-Ring with an inside diameter of 94.1 mm (3.705 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 105.5 mm (4.15 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists many alcohols, hydraulic fluids, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or strong acids are present.

You will find this material specified across construction equipment, hydraulic and pneumatic systems, and agricultural equipment.
