Copper union bypass SANHA 15 mm model 5086 (MPN 1508615)

Copper union bypass SANHA 15 mm model 5086 is a compact pipe fitting designed for connecting and bypassing sections in copper plumbing systems. It enables a secure mechanical joint between two 15 mm copper pipes while allowing isolation or rerouting of flow when maintenance or system modification is required. The fitting is suitable for use in heating, cooling and potable water installations where a reliable, low-profile union bypass is needed.

Advantages

The copper construction provides good thermal conductivity and corrosion resistance appropriate for potable water and heating environments. The union design permits disassembly without cutting the pipes, simplifying repair and replacement tasks. Its compact form factor saves installation space and supports a straightforward mechanical connection between two 15 mm copper lines.

Suitable for

• Connecting two 15 mm copper pipes in domestic and light commercial plumbing
• Bypassing sections of heating or cooling circuits for maintenance
• Creating a detachable joint for potable water distribution systems

Key specifications

• Material: copper
• Connection size: 15 mm nominal pipe diameter
• Function: union bypass for mechanical joining and rerouting
• Application: heating, cooling and potable water systems
• Form factor: compact union design for space-saving installation

How to use

Prepare the 15 mm copper pipe ends by cutting square, deburring and cleaning to ensure a proper mechanical fit. Assemble the union bypass according to the system orientation, making sure sealing surfaces are clean and aligned before tightening. Follow common plumbing practice for securing union fittings and verify that joints are seated correctly. After installation, pressurize and test the circuit for leaks following applicable standards and safety procedures.

Usage recommendations

Use with compatible 15 mm copper piping and fixtures. Inspect sealing faces and threads for damage before installation. For systems carrying potable water, follow local regulations and perform pressure and leak testing after assembly.
