Brass reducing coupling FERRO M14Z 6/4" x 5/4" yellow

FERRO M14Z is a brass reducing coupling with thread sizes 6/4" x 5/4" in a yellow finish, designed to connect pipes and fittings of different diameters. Made from brass, this reducing sleeve offers a metallic threaded transition that resists corrosion in typical plumbing and heating environments. It is intended for use where a reliable, threaded reduction is required for supply lines, radiators, valves and other water installations.

Advantages

The brass construction provides good mechanical strength and natural resistance to corrosion in potable water and heating systems. The yellow finish ensures easy visual identification and standard compatibility with brass fittings. The threaded design enables a secure mechanical connection without welding or soldering, allowing straightforward installation and maintenance in confined spaces.

Suitable for

• Adapting supply lines with different thread diameters
• Connecting radiators and valves requiring a reduced thread size
• Plumbing repairs and retrofits in residential and commercial installations
• Heating system connections where a threaded reduction is needed

Key specifications

• Material: brass
• Finish: yellow brass appearance
• Connection type: female threaded reducing coupling
• Thread sizes: 6/4" × 5/4" (reducing from larger to smaller diameter)
• Application environment: potable water, heating and general plumbing

How to use

Ensure mating threads on pipes or fittings are clean and free of debris. Apply an appropriate thread sealant or PTFE tape to the male threads according to local plumbing practice. Hand-start the coupling onto the male thread, then tighten with suitable wrenches until a secure, leak-tight connection is achieved; avoid excessive torque that could damage threads. Check the assembled joint under system pressure for leaks and retighten if necessary following recommended torque limits for brass fittings.

Usage recommendations

Use compatible thread sealants for potable water systems and follow local plumbing codes. Avoid exposure to highly acidic or alkaline fluids and dissimilar metals without appropriate dielectric isolation to reduce galvanic corrosion risk.
