APG stocks the H1.6X37.1, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 37.1 mm (1.461 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 40.3 mm (1.59 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The compound resists greases and lubricants, hydraulic fluids, and water. Buna-N (Nitrile) is specified for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or ketones will shorten service life.
Maintenance and OEM teams specify it across agricultural equipment, hydraulic and pneumatic systems, and general industrial maintenance.
H1.6X37.1 ships individually. 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.
