APG stocks the H3.5X106, a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 106 mm (4.173 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 113 mm (4.45 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to greases and lubricants, many alcohols, and hydraulic fluids. Buna-N (Nitrile) is known for low compression set under sustained load and an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).

Common environments for this compound include fluid power, hydraulic and pneumatic systems, and general industrial maintenance.

H3.5X106 ships individually. Unit weight is approximately 0.0041 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
