Manufactured by KAN-therm, this coupling provides a durable metallic connection suited for plumbing and heating installations where a reliable transition between 18 mm copper or PEX pipe and R3/4 threaded fixtures is required. Use cases include radiator connections, boiler hookups, and general water distribution in residential and light commercial systems.

## Long description

KAN-therm Złączka GZ Copper 18 R3/4 is a copper fitting for connecting 18 mm copper or PEX tubing to a component with an R3/4 female threaded port. Designed for plumbing and heating systems, this metallic coupling creates a stable, corrosion-resistant transition between a smooth 18 mm pipe and standard R3/4 threaded fixtures commonly used on radiators, boilers and distribution valves.
Advantages
The fitting is made of copper, offering good thermal conductivity and long-term resistance to water corrosion. Its cylindrical connection for 18 mm pipe ensures a tight mechanical fit when combined with appropriate compression rings or soldering techniques. The R3/4 male thread provides compatibility with common heating and plumbing components, delivering a robust metallic joint suitable for domestic and light commercial installations. The simple geometry of the coupling reduces flow restriction at the junction and supports reliable sealing with standard thread sealants or tape.
Suitable for
Connecting 18 mm copper or PEX pipe to radiators and radiator valves
Boiler and heat source connections with R3/4 threaded ports
Domestic hot and cold water distribution lines
Service and repair work in residential and light commercial plumbing
Key specifications
Material: copper
Connection to pipe: for 18 mm smooth copper or PEX tubing
Thread type: R3/4 male thread for mating with R3/4 female ports
Application: plumbing and heating systems
Connection method: suitable for compression fittings or soldered joins depending on installation practice
How to use
Prepare the 18 mm pipe by cutting it square and deburring the outer edge. Depending on installation practice, slide the appropriate compression ring and nut onto the pipe or prepare the joint for soldering. Apply thread sealant or PTFE tape to the R3/4 male thread before engaging with the mating female port. Tighten the threaded connection to the torque recommended for the mating component while ensuring the pipe end is fully inserted for a secure seal. Pressure-test the assembly according to local plumbing standards after installation.
Usage recommendations
Use compatible compression rings, nuts or brazing/soldering procedures recommended for copper fittings. Select appropriate thread sealant for potable water systems if required, and follow local codes for pressure testing and thermal expansion allowances in heating circuits.
