Description: Style AG40NBRMG is a 40 durometer mid-grade nitrile gasketing material designed for gasketing applications that require a solid rubber material that provides oil and solvent resistance. Also known as Buna-N, Style AG40NBRMG is manufactured for applications that do not require the higher percentage of nitrile that our high grade nitrile (AG40NBRHG) offers. 40 durometer mid-grade nitrile provides users with a service temperature range of -30°F to +200°F.
Atlantic Gasket’s mid-grade nitrile is available in a wide range of durometers, ranging from as soft as 40 Durometer (AG40NBRMG) to as hard as 80 Durometer (AG80NBRMG) with standard durometers in between. Style AG40NBRMG is available in the color black and can be manufactured in a wide range of standard thicknesses, ranging from as thin a 1/32" to as thick as 1/4", with custom thicknesses available upon request. 40 durometer mid-grade nitrile has a smooth finish and can be converted into rolls ranging from as narrow as 1/4 wide up to 48" in width. Custom widths can be manufactured upon request. Atlantic Gasket has the ability to fabricate 40 durometer mid-grade nitrile by die-cutting or waterjet cutting to meet your design and production requirements.
