## Long description

FERRO RN05Z 1x3/4" brass reducing fitting is a threaded coupling designed to connect pipes or fittings of differing diameters. Manufactured from brass, the reducer provides corrosion resistance and mechanical durability for water installations, heating systems and general plumbing repairs. The fitting facilitates a secure and leak-minimised threaded transition from a 1" connection to a 3/4" connection, enabling straightforward integration into existing plumbing networks.
Advantages
The brass construction offers good resistance to corrosion and wear while maintaining dimensional stability under normal hydraulic conditions. Threaded connections ensure a mechanically firm joint without the need for welding or soldering, allowing for quick assembly and disassembly during maintenance. The compact design occupies minimal space in pipe runs and is compatible with standard threaded plumbing components for reliable interoperability.
Suitable for
Domestic and commercial water supply systems
Central heating and radiator connections
Plumbing repairs and retrofits where diameter transition is required
Connecting valves, taps and other threaded fittings of different sizes
Key specifications
Material: brass (corrosion-resistant alloy)
Connection type: threaded reducing coupling
Primary connection sizes: 1" to 3/4"
Application: potable water systems, heating circuits and general plumbing
Design: compact threaded reducer for inline installation
How to use
Ensure pipe ends and mating fittings are clean and free of debris or old sealant before assembly. Apply an appropriate thread sealant or PTFE tape to the male threads to improve leak tightness. Hand-start the threads to avoid cross-threading, then tighten using an appropriate wrench until secure; avoid over-tightening to prevent thread damage. Check the joint under operating pressure and re-tighten if minor leaks are detected after initial commissioning.
Usage recommendations
Use compatible sealants and follow local plumbing codes. For potable water installations, select sealing materials approved for drinking water. Inspect threaded joints periodically as part of routine maintenance, and replace the fitting if signs of severe corrosion or thread wear occur.
