Your description does not enlighten me... there are all sorts of radiators available here. > Most of the European systems are geared towards PEX tubing, and > compression > fittings... and untapered pipe thread with jamb nuts and O-rings. PEX tubing has been "certified", but Prisol tubing (ie soft bendable Cu with plastic "coating") is much more common here. Cu tube joints are made with "nut", "support cylinder" and a "squeeze ring". > Runtal, Cordivari, Wirsbro and Wesaunard are examples I have run into.
