Brass reducing coupling FERRO M12Z 1¼" x 1" (reducing fitting)

FERRO M12Z 1¼" x 1" is a brass reducing coupling designed to join threaded pipes and fittings of different diameters in plumbing and heating systems. Constructed from brass, the reducing fitting offers corrosion resistance and mechanical durability suitable for domestic and light commercial installations where a transition from 1¼" to 1" pipework is required.

Advantages

The brass construction ensures long-term resistance to corrosion and scaling compared with some other materials, while threaded connections allow for a secure, leak-resistant joint when properly installed with sealing material. Its compact design facilitates installation in confined spaces and provides stable mechanical strength for typical water and heating applications.

Suitable for

• Connecting 1¼" to 1" threaded pipes in potable water systems
• Reducing pipe diameter in central heating and radiator circuits
• Plumbing repairs and retrofit work in domestic and light commercial settings
• Joining brass, copper or compatible threaded fittings

Key specifications

• Material: brass
• Connection type: threaded reducing coupling
• Sizes: 1¼" (larger end) x 1" (smaller end)
• Application: plumbing and heating systems
• Suitable mediums: water, heating fluids compatible with brass

How to use

Prepare threaded pipe ends by cleaning and removing debris or old sealant. Apply an appropriate thread sealant or PTFE tape to the male threads to ensure a leak-tight joint. Hand-start the coupling onto the male thread and tighten with suitable tools until secure; avoid excessive torque to prevent thread damage. After installation, pressurize the system and inspect the joint for leaks, retightening slightly if necessary according to fitting and sealant manufacturer guidance.

Usage recommendations

Use compatible thread sealants or PTFE tape rated for potable water or heating systems. Avoid exposure to aggressive chemicals not compatible with brass. For systems operating at elevated temperatures or pressures, verify that the fitting and sealing materials meet the system’s specifications and local plumbing codes.
