Brass coupling FERRO M06Z 6/4" (6 over 4 inches) threaded pipe fitting

FERRO M06Z brass coupling 6/4" is a threaded pipe fitting designed to join pipes with a size transition from 6" to 4" (6 over 4 inches) in applications where a change of diameter or thread standard is required. Manufactured from corrosion-resistant brass, the coupling provides a robust mechanical connection suitable for water and heating systems. The part is intended for installation in plumbing lines where a reliable threaded joint is needed and where sealing is achieved with compatible sealing tape or joint compound.

Advantages

The brass construction offers good corrosion resistance and mechanical strength while remaining easy to machine for accurate thread engagement. The threaded design enables a detachable yet secure connection, simplifying maintenance and replacement. The coupling is compact and suitable for confined spaces where a direct threaded transition is necessary, and it is compatible with standard pipe threading practices when appropriate sealing materials are applied.

Suitable for

• Residential and commercial water supply lines
• Heating system pipe connections
• Changes of pipe diameter or threaded standard in plumbing installations
• Repairs and retrofits where threaded fittings are required

Key specifications

• Material: brass with corrosion-resistant properties
• Connection type: threaded coupling for size transition
• Size transition: 6/4" (6 over 4 inches) threaded connection
• Application medium: water and heating fluids
• Compatibility: designed for standard threaded pipe systems when used with appropriate sealing

How to use

Before assembly, ensure mating threads are clean and undamaged. Apply suitable sealing tape or joint compound to the male threads according to manufacturer recommendations to achieve a leak-tight joint. Hand-start the coupling onto the male thread to avoid cross-threading, then tighten with appropriate tools until secure; avoid over-tightening to prevent thread or fitting damage. Inspect the joint after pressurization and re-tighten if necessary following safe working practices for the system.

Usage recommendations

Use only sealing materials compatible with potable water or heating systems as required. For critical or high-pressure installations, follow local regulations and consider professional installation to ensure correct thread engagement and sealing.
