H70024 is an AS568-024 black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 1.114 in (28.3 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.254 in (31.85 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.
This material stands up to many alcohols, petroleum-based oils, and greases and lubricants. Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or ketones are present.
It sees regular use in agricultural equipment, automotive, and general industrial maintenance.
H70024 ships individually. Unit weight is approximately 0.2972 g. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
