Brass axial fittings are designed for connecting cross-linked polyethylene (PEX) pipes and high-temperature resistant polyethylene (PE-RT) pipes. The fittings are suitable for both hot and cold water in hydro-sanitary systems, radiator and underfloor heating systems, or cooling systems. They allow for the installation of piping both above ground and underground. Thanks to the installation of axial fittings, a stable and watertight connection is achieved without the use of additional O-rings, which does not require maintenance.

​

The installation of the pipe outside the fitting is carried out using an easy-to-use manual tool, which, through a reamer, "widens" the ends of the pipe and fits it onto the fitting. The pipe on the fitting is then tightened by the presence of the appropriately sized sleeve.

The main characteristics of axial fittings are as follows: durability over time, greater water flow, resistance to high temperatures, and versatility.
