Due to its special physical properties graphite is perfectly suited for seals in fittings, pumps and exhaust systems, for example. High temperatures and/or aggressive media pose no problems for
graphite ring and/or pure graphite rings made by Adtech.
Since the 1970's we have resolutely continued to further develop our know-how – to perfection. Our unique and extensive inventory of tools is unequalled anywhere on earth, putting us in a position to manufacture and deliver virtually any ring geometry requested by our customers and to do so promptly – in an industrial quality of up to 99.85 % and with a density of between 1.2 and 1.8 g/cm3.
Pure graphite rings by Adtech are in use all over the world, protecting people and the environment from problematic media (liquids and gases). Whether infinite, divided or bias-cut: we produce graphite rings in a huge range of sizes. The outside diameters are between three and 1,150 mm; the height is totally variable. Our pure graphite products are available in a variety of typical ring shapes
Typical applications of our technology include bonnet gaskets, sometimes referred to as Brettschneider rings. They are provided with inclined surfaces specified by the customer on the inner or outer diameter, and they withstand pressures of up to 700 bar. Our spherical exhaust gaskets are reinforced with a wire mesh and are used by many automobile manufacturers.
