## Long description

Copper reducing coupling SANHA 5243 28 x 18 mm is a precision-made fitting for joining copper pipes of different diameters. Manufactured from copper to provide durable mechanical strength and reliable hydraulic sealing, this reducing coupling is intended for plumbing and heating installations where a stepped connection is required between a 28 mm and an 18 mm copper tube. The design supports potable water systems, central heating circuits and general installation work with standard copper tubing.
Advantages
The SANHA reducing coupling combines corrosion-resistant copper construction with accurate dimensions to ensure consistent fit and long-term performance. Its smooth internal bore minimizes flow disturbance and pressure losses at the transition between pipe sizes. Manufactured to industry tolerances, the coupling provides a secure mechanical and hydraulic joint when installed correctly with the appropriate joining technique for copper fittings.
Suitable for
Joining 28 mm to 18 mm copper pipe in potable water systems
Reducing connections in central heating and radiator circuits
General plumbing installations requiring a stepped copper joint
Key specifications
Material: copper
Connection type: reducing coupling for copper pipe
Inlet diameter: 28 mm
Outlet diameter: 18 mm
Application: potable water, heating, general installation
How to use
Prepare pipe ends by cutting square and deburring to ensure full insertion and a smooth joint face. Fit the 28 mm and 18 mm copper pipes into the respective ends of the coupling. Join according to the chosen copper joining method (soldering, brazing, or approved compression method) and follow applicable local codes and manufacturer recommendations for heating and potable water installations. After joining, inspect the connection for proper seating and test the system under operating pressure to confirm hydraulic tightness.
Usage recommendations
Use suitable flux and cleaning procedures prior to soldering or brazing to ensure reliable seals. Select the joining technique compatible with the system type and temperature/pressure requirements. For potable water installations, verify materials and joining methods meet local drinking water regulations.
