Copper endfeed fittings for high operating pressure


FRABO G-SIZE is the Cu-DHP (material CW024A in compliance with EN 1412) copper solder fitting series, available in a dimensional range between 22 and 133 mm and realized in compliance with EN 1254-1 European standard. 

FRABO G-SIZE fittings are designed and produced to realize soldered junctions, which have to handle high working pressures and heavy mechanical stress: these applications are difficult to manage by using traditional fittings and they requires high-quality products and reliability. 


FRABO G-SIZE fittings are characterized by a wall thickness higher than the minimum required by UNI EN 1254-1 standard. 

For more detailed information on products installation and fields of application, it is necessary to refer to the technical data sheets available in the DOWNLOAD section of the website.

The G mark immediately identifies the G-SIZE range

Thanks to the increased wall thickness, FRABO G-SIZE fittings are suitable for many industrial applications such as, for example, high-pressure gas distribution systems, solar systems, compressed-air system and installations for the industrial refrigeration.

Fields of application
refrigerazione_industriale Industrial refrigeration
aria_compressa Compressed air systems
solare Solar
industriale Distribution of technical gases with high pressures

Compressor tandemization/connection


Maximum operating pressures allowable (Bar) ¹


S = Safety factor in reference to the burst pressure.

¹ Maximum pressures are based on an installation carried out using strong brazing according to applicable rules of good practice.

  • Increased wall thickness. 
  • Resistance to higher operating pressures than those which can be handled by common solder fittings.
  • Resistance to heavy working conditions such as in installations where there are intense mechanical vibrations.
  • Resistance to heavy mechanical stress.
