Established in 1978, Comer spa is an Italian company leader in production and distribution of thermoplastic valves and fittings. Over the years Comer has a strong growth and has several different production sites, including the two latest locations near Genoa in Italy: San Colombano Certenoli, owned by Comer since 1990 and specialized in valve manufacture, and Casarza Ligure, estabilished in 2004 and specialized in fittings production, especially large diameters. Despite our success, Comer remains a family-owned company, which is still managed by the founder Mr. Compagnoni.
