USA NOTES: 1) This does not appear to have adaptors to US standard National Pipe Thread. 2) This is for so-called 2 pipe radiators. It is not for the single pipe system (the ones with the hissing air valve on one end of the radiator.

It has aesthetic defects and the interior is dusty, which could have happened during manufacturing. Apart from that, I think I will find it useful.
