Copper Bypass SANHA 5085 18 mm (model 1508518)

Copper bypass SANHA 5085 18 mm is a prefabricated copper fitting designed for creating bypass connections and rerouting fluid flow in plumbing and heating systems. Manufactured by SANHA, this 18 mm bypass fitting is intended for use with copper pipe installations and can be combined with soldered or press-joined joints where a reliable bypass line is required. The fitting is suitable for domestic and light commercial applications where corrosion resistance and thermal conductivity of copper are advantageous.

Advantages

The SANHA copper bypass provides a compact and consistent solution for diverting flow or creating bypass loops without on-site fabrication. Its copper construction offers natural resistance to corrosion and good thermal transfer, which supports stable performance in heating systems. The prefabricated form ensures dimensional accuracy and reduces installation time compared with fabricating bends or tees from raw pipe. Compatibility with common joining methods for copper piping increases flexibility during installation.

Suitable for

• Bypass loops in domestic heating circuits
• Rerouting supply or return lines in plumbing installations
• Temporary or permanent bypasses during maintenance
• Light commercial water and heating distribution systems

Key specifications

• Material: Copper
• Nominal connection diameter: 18 mm
• Design: Prefabricated bypass fitting for copper pipe systems
• Compatible joining methods: soldering and press-joining for copper pipes
• Application environment: potable water and heating systems in domestic and light commercial settings

How to use

Prepare the copper pipes by cutting square, deburring and cleaning the pipe ends according to the chosen joining method. For soldered joints, apply appropriate flux and solder using controlled heating while maintaining alignment. For press-joined connections, insert the pipe fully into the fitting and apply the correct press tool and jaws specified for the pipe and fitting system. Ensure the bypass is oriented correctly in the system and verify flow direction if applicable. After joining, pressure-test the circuit according to local regulations to confirm leak-tightness before putting the system into service.

Usage recommendations

Follow manufacturer guidelines for compatible press tools, solder types, and flux when making connections. Ensure installations comply with local plumbing and heating codes. Use appropriate protective equipment when soldering and apply a pressure test after assembly. Consider thermal insulation on exposed bypass runs to reduce heat loss in heating systems.
