Product information

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.
