About Seybold
H. Seybold GmbH & Co. KG is a family business founded in 1876 and headquartered in Düren. The company is a specialist in sealing technology, occupational safety and industrial technology and supplies gasket materials both as semi-finished products and as fully finished gaskets. Flat gaskets made of elastomers, plastics and graphite are produced at short notice in-house; an in-house waterjet cutting machine cuts gaskets and plastic parts precisely to drawing or sample. The product range includes, among other things, fibre and graphite gaskets, elastomer gaskets, PTFE products, O-rings, metal and metal composite gaskets, high-temperature insulation materials as well as machined plastic semi-finished products. In addition, Seybold offers gasket calculations according to EN 1591-1, training according to DIN EN 1591-4, a repair service for mechanical seals, as well as stock-keeping and just-in-time production. As part of system business, the company supplies plants throughout Europe.
