Comer Spa

Comer s.p.a was established in 1978 thanks to the entrepreneurial skills of Stefano Compagnoni, who, after having gained a long experience in the mould manufacturing business, decided to found his own company. 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 Stefano. Compagnoni joined by his brother Giorgio and his daughter Roberta.

Since 1978 Comer s.p.a has been producing by the injection-moulded technology pipe fittings and valves in thermoplastic material (PVC, ABS, PP, PE), designing and manufacturing our own moulds and work shop tools to the highest standards.

Design and manufacture of molds

The molds used for the production of our fittings and valves are made on site in a specialized department. Since the foundation of Comer, we have developed and increased both our technical know-how to design moulds and our skills for mould-technology production. Thanks to this long experience gained in manufacturing moulds and our precision equipment with the latest CAD and CAM technologies, we can respond in a very short time to our customers’ needs both to modify current products and, if necessary, to design articles from scratch.

The production and final markets

The Comer product consist of a comprehensive range of both U-PVC and ABS valves and fittings with solvent cement and BSP threaded standard joints, as well as PE100 and PPH butt-weld fittings. The wide range of Comer products are suitable for many markets and applications: such as the chemical industry, municipal water distribution, irrigation installations and in general for every application for pipeline systems with pressure up to 16 bar. In particular for the food industry which is a specific sector where Comer products meet the most stringent international regulations for U-PVC compatibility with alimentary fluids.
