Copper union bypass SANHA 18 mm model 1508618

Copper union bypass SANHA 18 mm model 1508618 is a copper union fitting designed to connect, isolate or create a removable bypass in 18 mm copper piping systems. Manufactured by SANHA for use in potable water and central heating installations, this union fitting provides a threaded connection that enables easy disassembly for maintenance, replacement or rerouting of pipe sections without soldering or permanent joints.

Advantages

The SANHA copper union bypass offers a corrosion-resistant copper construction suitable for contact with potable water and heating media. Its threaded union design permits quick assembly and disassembly, reducing downtime during service tasks. The fitting supports a compact installation footprint and allows precise alignment of pipe runs while maintaining a reliable mechanical connection intended for repeated use.

Suitable for

• Domestic and commercial potable water supply lines with 18 mm copper tubing
• Central heating circuits where a removable union or bypass is required
• Service points that require isolation for maintenance or component replacement
• Temporary or permanent rerouting during system upgrades or repairs

Key specifications

• Material: copper
• Connection type: threaded union
• Nominal pipe diameter: 18 mm
• Application: potable water and central heating systems
• Function: removable bypass/union fitting for maintenance and isolation

How to use

Install the copper union bypass by preparing 18 mm copper pipe ends to the required length and ensuring clean, deburred surfaces. Thread the union components together by hand and tighten to the manufacturer's recommended torque to achieve a leak-tight mechanical connection. Use PTFE tape or appropriate sealing method on threaded surfaces if required by the installation standard or local practice. To service the line, loosen the union to separate pipe sections and reassemble after maintenance or replacement.

Usage recommendations

Use this SANHA copper union bypass in systems designed for copper piping and compatible fluid media. Verify local plumbing codes and pressure/temperature ratings for copper fittings before installation. Avoid excessive mechanical stress on the union; support adjacent piping to prevent strain. For potable water systems, follow hygiene and flushing procedures after installation or maintenance.
