## Summary description

Conex coupling for soldered and threaded connections, size 15x3/8" in bronze, model 4270G015003000. Designed to join pipes and fittings using either soldering or threaded joints, suitable for plumbing and heating installations. The bronze construction offers corrosion resistance and mechanical strength for potable water and central heating systems.

## Long description

Conex coupling for soldered and threaded connections 15x3/8" bronze (model 4270G015003000) is a dual-purpose joining fitting engineered for plumbing and heating installations. The coupling combines a solderable end and a threaded end to connect copper or compatible metal pipes and fittings where a transition between a soldered joint and a threaded connection is required. Manufactured in bronze to provide corrosion resistance and mechanical durability, this coupling is suitable for potable water and central heating systems and for locations where reliable leak-tight joints are needed.
Advantages
The bronze construction delivers enhanced corrosion resistance compared with standard brass in aggressive water environments and maintains mechanical strength under typical domestic and light-commercial pressures. The dual-connection design simplifies installation by allowing a soldered joint on one side and a standard 3/8" threaded connection on the other, reducing the need for additional adapters. The coupling's dimensional compatibility with 15 mm tubing and 3/8" threaded fittings supports common plumbing geometries and streamlines repairs and modifications.
Suitable for
 Joining 15 mm copper pipe to 3/8" threaded fittings
 Potable water distribution systems
 Central heating circuits and radiator connections
 Plumbing repairs where a transition from soldered to threaded connection is required
Key specifications
 Material: bronze
 Connection types: one end for soldering (15 mm), one end threaded (3/8")
 Nominal pipe size: 15 mm to 3/8" thread
 Application: potable water and heating systems
 Mechanical characteristics: corrosion-resistant, suitable for domestic and light-commercial water pressures
How to use
Prepare the pipe and fitting surfaces by cleaning and deburring the 15 mm copper tube and the mating threaded component. For the soldered end, apply appropriate flux and solder according to standard plumbing practice, heating evenly until proper capillary flow is achieved. For the threaded end, apply an appropriate sealing method such as PTFE tape or pipe joint compound to the male thread before assembly to ensure a leak-tight joint. Tighten the threaded connection to recommended torque values for the mating fittings and check all joints visually and by pressure testing before putting the system into service.
Usage recommendations
Use the coupling in systems operating within normal domestic water and heating temperature ranges and ensure compatibility of all materials in contact with potable water. Avoid using the fitting with incompatible fluids or in environments where galvanic corrosion could occur without proper isolation. Follow local plumbing codes and manufacturer guidance for soldering practices, pressure testing, and maximum allowable operating pressures and temperatures.
