Galvanised Reducing Coupling 6" x 3

This galvanised reducing coupling joins a six-inch female NPT thread to a three-inch female NPT thread in plumbing and bathware installations. It is supplied new from Legend Valve for use in water supply or drainage systems where a straight reduction is required.

Thermal and Power Characteristics

The fitting is a passive metal component with no moving parts, electrical connections or active cooling. It produces no noise, draws no power and its temperature follows the fluid passing through it.

Installation Fit and Clearance

The coupling threads directly onto matching FNPT pipe ends without additional adapters, freeing the installer from sourcing separate bushings or reducers. It requires compatible six-inch and three-inch FNPT pipework and thread sealant for a watertight joint. Builders needing a different reduction ratio or a non-galvanised finish must select another fitting.

Questions about this item

How do I install the 6" x 3" galvanized reducing coupling with FNPT threads?

Wrap PTFE tape clockwise on the male threads, hand-tighten the coupling, then finish with a wrench; the common mistake is over-tightening and cracking the galvanized finish.

Will the galvanized coating need replacement or recoating later?

The zinc layer protects the steel until it erodes; inspect joints annually for white rust and plan to replace the fitting once red rust appears on the threads.

What pressure or temperature limit appears first during sustained hot-water use?

The galvanized iron body and FNPT seal typically reach their continuous-service temperature ceiling before the pressure rating becomes critical.
