The H7X236 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 236 mm (9.291 in), a cross section of 7 mm (0.276 in), and an outside diameter of 250 mm (9.84 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The compound resists hydraulic fluids, water, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for low compression set under sustained load, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or polar solvents are present.
Maintenance and OEM teams specify it across hydraulic and pneumatic systems, agricultural equipment, and general industrial maintenance.
Order part number H7X236, sold individually. Unit weight is approximately 36.318 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
