verified company

Isotubi, S.L., has been working in the stainless-steel world for more than 40 years.


Isotubi, S.L., is a company able to offer a competitive product which meets the most important quality requirements in the international markets.

We are presenting our range of NUMEPRESS products, the stainless-steel tube and Pressfitting system which allows making facilities in a very easy way, without using welding or threads, saving a considerable amount of time and money.


Our factory and warehouse, located in Barcelona, has an important stock at our customer’s disposal, so delivery terms are extremely short. As we are manufacturers, we can also offer specialized products to our customers when needed.


These are the main applications of our system: compressed air, heating facilities, sanitation facilities, fire-extinguishing system (sprinkler), solar energy, plumbing, industrial facilities, shipping facilities and mining.


Our main challenges are to know about the concrete needs of our customers, to adapt our products and processes to the new technologies and to make a constant effort in improving our customer service.


Both our production and quality control processes are certified by TÜV according to the ISO 9001 norm. We also hold the main European Approvals for our products and processes: AD Merkblatt (Germany), 2014/68/EU Pressure Equipment Directive, CERTIF (Portugal), DVGW (Germany), Numepress TÜV product certificate (Spain and Portugal), LLOYDS, WATERMARK, SITAC, CSIRO, NSF, FM, WRAS, STO, ABS and DNV Approval for ships.
