## Summary description

FERRO R09Z is a brass reducing coupling with female threads 1¼" x ¾" designed for plumbing installations. Made of corrosion-resistant brass, it provides a secure transition between different pipe diameters, suitable for water supply, heating systems and sanitary fittings. Use for connecting fixtures, valves and adapters where diameter reduction is required.

## Long description

FERRO R09Z is a brass reducing coupling with female threads 1¼" x ¾" designed for plumbing installations. Made from corrosion-resistant brass, this fitting provides a reliable mechanical connection to join pipes or components with different diameters. The coupling facilitates a smooth transition between larger and smaller threaded fittings used in water supply, heating circuits and sanitary systems, ensuring a compact and leak-resistant joint when installed correctly.
Advantages
The brass construction offers durability and resistance to corrosion in typical domestic and light-commercial plumbing environments. Female threaded ends on both sides enable straightforward assembly with male-threaded pipes, valves or adapters without the need for soldering. Its reducing design saves space and simplifies the layout where a change of pipe diameter is needed, and the standardized thread sizes support compatibility with common plumbing components.
Suitable for
 Connecting a 1¼" threaded pipe or fitting to a ¾" piped fixture
 Water supply lines in residential and small commercial buildings
 Heating system branches and radiator connections
 Sanitary fittings and bathroom fixture adapters
Key specifications
 Material: corrosion-resistant brass
 Connection type: female threaded on both ends
 Thread sizes: 1¼" (larger end) and ¾" (smaller end)
 Function: reducing coupling for diameter transition
 Typical applications: potable water, heating, sanitary installations
How to use
Before installation, verify thread compatibility and clean mating threads to remove debris. Wrap the male threads with an appropriate sealing tape or apply a suitable thread sealant compatible with potable water if required. Hand-start the coupling onto the male thread and then tighten with a wrench until secure, avoiding over-tightening that could damage threads. After installation, pressurize the system and inspect the joint for leaks; if necessary, tighten incrementally or reapply sealant and retest.
Usage recommendations
Use the coupling in systems within the manufacturer’s recommended temperature and pressure limits for brass fittings. Avoid exposure to aggressive chemicals or environments that may accelerate dezincification. For potable water installations, ensure sealants and tapes are rated for drinking water use. When joining dissimilar metals, consider using dielectric unions or appropriate isolation to prevent galvanic corrosion.
