## Long description

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.

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.
