Solyem is a static Gasket expert company based in Saint Priest near Lyon in France.


Founded in 1882 near Lyon by Mr Curty, Solyem was an aluminium foundry manufacturing fireplace plates and offering maintenance for boilers.


Mr Curty registered the first major patent: the “Metalloplastic” gasket, a U-shaped copper piece covering a fibre ring made with asbestos. This gasket was originally used on steam engines. From this day on, the core activity of Solyem has never changed and has been subject to multiple upgrades and innovations.


Growth with the automotive industry: “Curty & Cie”, the famous brand, switched its activity focus from steam engines to the automotive industry. The company assisted car manufacturers in the sealing of their systems and grew into a successful gasketing company.


Pechiney Ugine Kuhlmann acquired “Curty & Cie’’ within its gasket division called CELIFAC. In 1977 Turner & Newall Group bought “Curty & Cie” from Pechiney and appointed them 3 years later to the famous British company Coopers PAYEN, also experts in the conception of gasket solutions.


FEDERAL-MOGUL publicly took over Turner & Newall group and integrated “Curty & Cie” within its Powertrain Sealing and Bearing Division.


Registration of the second major patent: the LEM gasket technology.


The company was bought by the Zhongding group and renamed SOLYEM, French acronym for SOciété LYonnaise d’Étanchéité Mécanique or in English: Lyon mechanical sealing manufacturer.
