Brass reducing nipple FERRO N20Z, reducing coupling 2 x 6/4" (yellow brass)

Brass reducing nipple FERRO N20Z, reducing coupling 2 x 6/4" (yellow brass) is a threaded reducing coupling made of yellow brass for connecting pipes or fittings with sizes 2 x 6/4". Designed for plumbing applications, it provides a reliable mechanical and fluid-tight connection between differing thread diameters and is suitable for use in hot and cold water installations as well as general pipework where a reduction in thread size is required.

Advantages

The coupling is manufactured from yellow brass, offering corrosion resistance and good machinability for accurate thread engagement. Its reducing design allows secure joining of different thread diameters without the need for soldering or welding, simplifying installation and maintenance. The threaded connection ensures a tight seal when used with appropriate sealing materials and torque, and the compact form factor makes it suitable for confined spaces in residential or commercial plumbing systems.

Suitable for

• Connecting pipes or fittings with different thread diameters (2 x 6/4").
• Hot and cold water plumbing installations.
• Domestic and light commercial pipework where reduction is required.
• Repairs or retrofitting existing threaded plumbing connections.

Key specifications

• Material: yellow brass (brass alloy) for corrosion resistance and strength.
• Type: threaded reducing nipple / reducing coupling.
• Connection sizes: larger thread and smaller thread for 2 x 6/4" configuration.
• Application: potable water, general plumbing for hot and cold water systems.
• Design: compact, cylindrical form suited for confined installations.

How to use

Ensure both mating threads are clean and free from debris or old sealing compound. Apply an appropriate thread sealant such as PTFE tape or approved pipe joint compound to the male threads, wrapping in the direction of thread engagement to avoid unwrapping during assembly. Hand-start the coupling onto the mating thread to ensure correct alignment, then tighten with a suitable wrench to the recommended torque for the thread size and material. After installation, verify the connection for leaks under normal system pressure and re-torque if necessary following plumbing best practices.

Usage recommendations

Use compatible sealing materials and avoid over-tightening to prevent thread damage. For installations in aggressive environments or when higher temperatures or pressures are expected, verify material suitability and system ratings before use. Periodically inspect threaded connections for signs of corrosion or leakage and replace if deterioration is observed.
