Product information

Description

The Conex copper solder sleeve 5240 is designed to create reliable soldered joints between copper tubes with dimensions 35×28 mm. This sleeve functions as both a mechanical coupling and a soldered connection element, enabling a sealed and conductive joint when correctly installed and soldered. It is intended for use with compatible copper piping in plumbing and heating systems, and is suitable for both repair work and new installations.

Advantages

The copper construction ensures good thermal conductivity and corrosion resistance appropriate for potable water and heating circuits. Its stepped internal profile accommodates the 35×28 mm tube sizes, providing proper alignment and a consistent joint gap for solder to flow. The sleeve reduces assembly time compared with forming complex fittings on-site and delivers a compact connection that maintains pipe strength and hydraulic performance when soldered correctly.

Suitable for

  • Repairing damaged copper pipelines
  • Joining copper pipes in domestic heating systems
  • Connecting copper tubing in potable water installations
  • Retrofit and tight-space plumbing where a compact soldered joint is required

Key specifications

  • Material: copper
  • Connection type: solder sleeve for capillary soldering
  • Compatible tube outer diameters: 35 mm and 28 mm
  • Application: plumbing and heating pipeline joints
  • Fitment: stepped internal profile for concentric alignment

How to use

Prepare the copper tube ends by cutting square, deburring, and cleaning the surfaces to bright copper where solder will flow. Insert the tubes fully into each side of the sleeve until they meet the internal stop, ensuring correct alignment for the 35 mm and 28 mm ends. Apply an appropriate flux to the joint area and heat evenly with a torch until the solder flows into the seam by capillary action. Allow the assembly to cool naturally and then check the joint for continuity and leaks before putting the system back into service.

Usage recommendations

Use only flux and solder suitable for potable water or heating systems, and follow local regulations and safety practices for brazing/soldering. Verify tube compatibility and dimensional fit before installation. For pressure-critical or safety-related systems, perform a pressure test after installation to confirm joint integrity.
