APG stocks the H4X330, a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 330 mm (12.992 in), a cross section of 4 mm (0.157 in), and an outside diameter of 338 mm (13.31 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Expect good resistance to many alcohols, water, and petroleum-based oils. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or polar solvents will shorten service life.
Common environments for this compound include agricultural equipment, automotive, and general industrial maintenance.
Order part number H4X330, sold individually. Unit weight is approximately 15.962 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
