## Summary description

Conex 5240 is a copper coupling designed for soldered pipe connections measuring 42x35 mm. Intended for joining copper pipes, this soldered coupling provides a permanent metal-to-metal connection suitable for plumbing and heating systems. The fitting is used where a durable, leak-resistant joint is required in water and heating installations.

## Long description

Conex copper soldered coupling 5240 for soldered joints 42x35 mm is a reducing coupling made from copper for permanent soldered connections between pipes with diameters 42 mm and 35 mm. Designed for use in water and heating systems, this coupling creates a metal-to-metal joint that, when correctly soldered, delivers a durable, leak-resistant connection suitable for both domestic and light commercial installations.
Advantages
The coupling's copper construction ensures good thermal conductivity and corrosion resistance in typical plumbing environments. Its reducing design enables secure joining of dissimilar pipe sizes without the need for additional adapters. When properly soldered, the joint provides long-term mechanical strength and reliable sealing for potable water, central heating, and similar fluid systems.
Suitable for
Joining copper pipes of 42 mm to 35 mm diameter in plumbing systems
Repairs and modifications in central heating circuits
Connections in potable water distribution where soldered joints are specified
Applications requiring a permanent, low-profile metal-to-metal connection
Key specifications
Material: copper
Type: reducing soldered coupling
Connection method: solder (brazing/sweating)
Pipe diameters: 42 mm × 35 mm
Application: water and heating installations
How to use
Prepare pipe ends by cutting squarely, deburring and cleaning the outside of the pipe and the inside of the coupling joint to remove oxides and contaminants. Apply appropriate flux designed for copper joints, assemble the coupling onto the pipes so the fitting fully covers the pipe ends, and heat the connection evenly with a suitable gas torch until the flux becomes active and solder flows. Introduce suitable solder to the joint and allow capillary action to draw solder around the interface. After cooling, inspect the joint visually and perform a pressure test as required by local regulations.
Usage recommendations
Use appropriate personal protective equipment and follow local codes. Select flux and solder compatible with potable water if used on drinking water systems. Ensure adequate ventilation when soldering and allow joints to cool naturally before applying pressure.
