Connector/Compression Adapter Varioterm ZZM1524 CU GW 3/4 x 15x1 Black Matte

Varioterm ZZM1524 CU GW 3/4 x 15x1 Black Matte is a copper compression connector/adapter designed to create a sealed mechanical transition between a 3/4" internal thread and a 15x1 tube. Finished in black matte, this fitting is intended for joining copper or compatible pipes and fittings in plumbing and heating systems. It provides a compact, durable connection suitable for installation in residential and commercial water and heating circuits where a reliable thread-to-tube adapter is required.

Advantages

The adapter offers a robust copper construction that resists corrosion and provides long-term mechanical strength for pressurized water and heating applications. Its compression-style connection ensures a sealed joint without the need for soldering, facilitating faster installation and maintenance. The black matte finish reduces visible reflections and can be used in installations where a discreet appearance is preferred.

Suitable for

• Connecting a 3/4" internal threaded fitting to a 15x1 copper tube
• Residential and commercial potable water supply lines
• Heating circuits and radiator connections
• Repairing or modifying existing copper pipework

Key specifications

• Material: copper (CU)
• Thread: internal 3/4" (female)
• Tube connection: 15 x 1 mm
• Connection type: compression/adapter
• Finish: black matte
• Intended use: water and heating systems

How to use

Ensure pipe ends and threaded fittings are clean and free of debris before assembly. Slide the compression nut and ferrule onto the 15x1 tube, insert the tube into the adapter until it seats firmly, then tighten the compression nut to the specified torque to form a sealed joint. Thread the adapter into the 3/4" internal thread and tighten to the appropriate sealing specification for your system. Follow general plumbing practice for support and alignment of connected piping to avoid undue stress on the fitting.

Usage recommendations

Use appropriate sealing materials on the threaded connection if required by the installation standard or system design. Verify compatibility with the pipe material and the system's maximum operating pressure and temperature. During installation, avoid over-tightening to prevent deformation of the tube or ferrule and inspect the joint for leaks after commissioning.
