Part number H7X280 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 280 mm (11.024 in), a cross section of 7 mm (0.276 in), and an outside diameter of 294 mm (11.57 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
As a material, Buna-N (Nitrile) is valued for low compression set under sustained load and an economical choice for high-volume maintenance programs. It resists hydraulic fluids, greases and lubricants, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving polar solvents or strong acids call for a different compound.
Typical settings include automotive, agricultural equipment, and hydraulic and pneumatic systems.
This item is sold individually under part number H7X280. Unit weight is approximately 42.718 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
