Graphite rings

Available in any desired ring geometries and dimensions

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 rings and/or pure graphite rings made by KLINGER^®.

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 do so promptly with an industrial quality of up to 99.85 % and with a density of between 1.2 and 1.8 g/cm3.

Broad spectrum of pure graphite solutions

Pure graphite rings by KLINGER^® Bartsch 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 large 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.

More variants through flanging

We modify graphite rings upon request, for example by flanging, which enhances the tightness and stability of the seal. Any inner diameter is possible here since we offer welded and unwelded eyelets. We provide seals with stainless steel caps or inserts, impregnated (such as PTFE or copper paste) or special graphite foils (including SIGRAFLEX^® APX foil for use at high temperatures). From loose wire mesh to (virtually impenetrable) stainless steel foil, we will help you configure the product to perfectly meet your requirements!

In addition to graphite rings, we also offer graphite tapes for universal sealing applications. The foils are smooth or textured and optionally self-adhesive. Our graphite tapes are also often used in combination with cam-profile gaskets (and spiral-wound gaskets) for especially exacting requirements, for example in the petrochemical industry.
