Press-fitting Systems

The most effective and efficient way to make an installation….


Pressfitting is a joining between pipes with fittings fitted through electro-mechanical pressing machines. Pressing permanently deforms the fitting on the pipe thus leading to a perfect mechanical joint, while the O-Ring provides for the hydraulic tightening connection. Pressing provides for a constant quality joining, easily reproduced and with a minimum physical effort by the operator


Safety, speed, reliability

Copper brazing is the most widely used method in the sanitary and plumbing sector. It asks for expertise and skills, long execution time and involves hot works and free flames. In case of maintenance or refurbishing, generally it is necessary to work in contact with inflammable materials, where the fire risk is very high
An alternative to brazing is the use of plastic pipes, adhesively jointed. No risk of fires connected to welding but cement resins need hours to dry, depending on the

Press-fitting stands out with many benefits. It lowers the execution times and it is safer: jointing is carried out at room temperature, with no glues, resins or free flames; the operator works in safety, even when in contact with inflammable materials. Pressing asks for 5 seconds for small diameters and up to 40 seconds for bigger diameters, consistently cutting installation times. What is more, fittings once pressed can be tested thus avoiding cost and downtimes. A 25 to 50% installation time reduction as reported by the company installers, on plants using big diameter pipes

RACMET Pressfit systems come in many fitting sizes to make the most complex installation simple to do

Press-fitting provides for the same benefits even when compared to threaded joints, as it is free of dirt and cuts depending on the threading process. No need to prepare the fittings, with hemp or Teflon as any joint comes with factory mounted O-Rings


Simple steps for reliable and defined results

The electromechanical tool presses the joint on the pipe through its jaws. The connection is permanent and irreversible and permanent. Pressing parameters such as pressure strength and time. Battery operated tools contribute to reduced weights and furthermore to simplify the job for the installer
