## Long description

SANHA Therm reducing tee 3xZW 18x15x18 is a copper press fitting designed for creating a branch in heating and plumbing pipework where the branch diameter differs from the run. The fitting provides a reduction from 18 mm to 15 mm and back to 18 mm, enabling secure transitions between pipe sizes in residential and commercial heating systems. It is manufactured for use with compatible press tools and sealing rings and is suitable for closed hot-water and heating installations where copper press technology is specified.
Advantages
The copper construction ensures good thermal conductivity and corrosion resistance while maintaining mechanical strength. The press connection design allows quick, cold joints without soldering, reducing installation time and fire risk on site. A reduced-diameter branch simplifies routing when space is limited or when connecting to smaller fixtures and circuits. The component is compatible with standard copper press systems and sealing elements, enabling reliable leak-free connections when installed with the correct press profile.
Suitable for
Creating branch connections in hot-water and heating circuits
Transitions between 18 mm and 15 mm copper pipes
Residential and small commercial plumbing installations
Repair and retrofit work where a reduced branch is required
Key specifications
Material: copper
Connection type: press-fit on all three ends
Nominal diameters: 18 mm (run) and 15 mm (branch)
Configuration: reducing tee (run-branch-run)
Application: closed hot-water and heating systems
How to use
Prepare pipe ends by cutting square and deburring the inner and outer edges. Slide the appropriate sealing rings or O-rings into place if required by the press system. Insert pipes fully into the fitting until they reach the stop. Use a compatible press tool and the correct jaw/profile for copper press fittings to perform the joint according to the tool manufacturer's instructions. After pressing, visually inspect each joint and, where applicable, perform a pressure test in accordance with local codes and project specifications.
Usage recommendations
Use only compatible press tools, jaws and sealing elements specified for copper press fittings. Confirm that the press profile matches the fitting design and follow local norms for heating system installation and pressure testing.
