Conex copper bypass pipe 15 mm model 5085 (Cu 15mm)

Conex copper bypass pipe 15 mm model 5085 (Cu 15mm) is a straight copper tube designed for plumbing and heating installations where a durable 15 mm connection is required. Manufactured from copper, the pipe offers corrosion resistance and is compatible with standard soldering and brazing techniques used in water supply and central heating systems. Its 15 mm outer diameter makes it suitable for creating bypasses, small branch connections or temporary reroutes in residential and light commercial piping work.

Advantages

The copper construction provides good thermal conductivity and long-term resistance to corrosion from potable water; this enables reliable performance in domestic hot and cold water systems and heating circuits. The smooth interior surface reduces the risk of flow resistance and scaling compared with some alternative materials. The product is compatible with common joining methods for copper pipework, including soldering, brazing and mechanical fittings designed for copper, allowing flexible installation options.

Suitable for

• Creating bypass lines in domestic water supply systems
• Forming short branch connections for radiators or heating loops
• Temporary reroutes during repair or maintenance of 15 mm copper circuits
• Use in potable water and central heating installations where copper pipe is specified

Key specifications

• Material: copper (Cu)
• Nominal diameter: 15 mm
• Form: straight bypass pipe (single length)
• Compatibility: suitable for soldering, brazing and mechanical fittings for copper
• Typical applications: potable water and heating systems

How to use

Measure and cut the 15 mm copper pipe to the required length using an appropriate pipe cutter to ensure a square, clean cut. Deburr and clean the pipe ends and fittings before joining. For soldered or brazed joints, apply flux, assemble the joint and heat evenly until the solder flows to form a continuous seal. If using mechanical fittings, follow the manufacturer's instructions for tightening and sealing. Ensure the assembled bypass is supported and secured to prevent movement and strain on joints. Pressure test the system after installation according to local codes and correct any leaks before returning the system to service.

Usage recommendations

Use appropriate personal protective equipment and work in a well-ventilated area when soldering or brazing. Verify water quality and system compatibility with copper piping, and follow local plumbing codes and standards for installation, support spacing, and pressure testing to ensure safe, long-lasting operation.
