The H4X14 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 14 mm (0.551 in), a cross section of 4 mm (0.157 in), and an outside diameter of 22 mm (0.87 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to water, greases and lubricants, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.
You will find this material specified across fluid power, construction equipment, and hydraulic and pneumatic systems.
