Copper union bypass SANHA 22 mm model 1508622 for plumbing connections

Copper union bypass SANHA 22 mm model 1508622 is a removable copper union designed for plumbing and heating systems. It connects two pipe ends while providing a bypass option for maintenance or temporary rerouting. Constructed from copper to resist corrosion, the fitting is suitable for potable water and central heating installations where a detachable metallic joint is required.

Advantages

This copper union bypass offers a durable, corrosion-resistant connection that simplifies disassembly and reassembly of piping circuits. The removable design enables quick isolation of a section for servicing without extensive cutting or soldering. Its metallic construction ensures compatibility with copper piping and provides reliable mechanical strength for residential and commercial plumbing applications.

Suitable for

• Domestic potable water supply lines
• Central heating circuits and radiators
• Temporary bypassing during repairs or maintenance
• Installation points where detachable unions are needed for system reconfiguration

Key specifications

• Material: copper
• Nominal diameter: 22 mm
• Type: removable union with bypass function
• Connection style: union joint suitable for copper pipes
• Corrosion resistance appropriate for potable water and heating systems

How to use

Install the union by preparing the pipe ends according to standard plumbing practice, ensuring clean, deburred surfaces for a secure joint. Align the union halves and tighten the union nut by hand, then apply the recommended torque with appropriate tools if specified by installation standards. Use the bypass feature to create a temporary alternate flow path during maintenance by connecting the bypass line and opening the bypass port. Follow local plumbing codes and guidelines for soldering, brazing, or sealing where required.

Usage recommendations

Verify material compatibility with existing copper piping and operating pressures. Ensure joints are properly tightened and checked for leaks before putting the system into regular operation. For potable water systems, confirm that materials meet local drinking water standards. When used in heating systems, check system temperature and pressure limits to ensure safe operation.
