Components for distribution lines

Regardless of its economic value and its size, each component of an optimised system must offer the maximum reliability.

This is why, with our range of pipes, fittings, manifolds and shut-off valves, we want to ensure not only constant performance levels but also absolute peace of mind throughout the working life of the system.



Plastic pipes (in PEX and PPR) or metal-plastic pipes (PEX-b/Al/PEX-b multilayer) for heating fluid distribution.


Thanks to our tradition and skills, we can offer a wide range of fittings and adaptors for every possible installation need.

Mechanical compression fittings or those with a metal seal, pressure fittings with multi-tong profile, and quick connection fittings: these are just a few of our product lines.


Simple and pre-assembled manifolds for distributing the heating fluid in various applications.

A wide selection of accessories is also available.

Ball valves

Brass ball valves for reliable shut-off operations in all heating and cooling systems.




Multilayer pipes available in coils or bars, also with thermal insulation for heating and cooling.

RM multitongs series brass fittings. These can be fitted with TH pressing profiles (Giacomini standard), H, U.

RM fittings characterized by:

Pipe-holder profile suitably chamfered to facilitate pipe entry;
stainless steel compression bush with special countersink to facilitate pipe entry;
black double o-ring seal;
Brass bush-fastener ring with slits for visual checks to ensure pipe is correctly inserted into frame;
Septum insulator to prevent corrosive electrochemical reactions from occurring on contact between the aluminium pipe and the brass of the fitting.

Brass manifolds for every application, made with cold-drawn bars or with stamped modules, for modular assembly according to requirements. Also available in pre-assembled configuration to facilitate on-site installation.
