## Summary description

Nut-to-nut coupling by Hydroland, galvanized finish, size 6/4. Designed to join two threaded fittings or pipes with corresponding 6/4 threads. Suitable for plumbing and fluid systems where a corrosion-resistant metal connector is required. Provides a secure mechanical connection for maintenance, repair, or extension of existing pipeline installations.

## Long description

Coupling nut-to-nut galvanized 6/4 Hydroland is a galvanized metal coupling designed to join two components with 6/4 threaded ends. Manufactured by Hydroland, the coupling provides a corrosion-resistant connection for plumbing and fluid systems where a mechanical threaded join is required. The product is intended for use in maintenance, repair, or extension of existing pipeline installations and is suitable for a range of non-pressurized and low-pressure applications consistent with galvanized fittings.
Advantages
The galvanized finish offers enhanced corrosion resistance compared with untreated steel, extending service life in moist or mildly aggressive environments. The nut-to-nut design allows straightforward installation between two male threaded fittings without the need for welding or specialized tools. The coupling’s standardized 6/4 thread size ensures compatibility with components made to the same thread specification, facilitating repairs and system modifications.
Suitable for
Joining two male-threaded pipes or fittings with 6/4 threads
Plumbing repairs and extensions in residential or light-commercial systems
Non-pressurized or low-pressure fluid lines where galvanized fittings are acceptable
Temporary or permanent mechanical connections during maintenance work
Key specifications
Material: galvanized metal for improved corrosion resistance
Connection type: nut-to-nut threaded coupling
Thread size: 6/4 (six quarters) compatible with matching 6/4 male threads
Application: plumbing and fluid systems for mechanical joining of threaded components
How to use
Ensure both mating male threads are clean, free of debris and undamaged. Apply appropriate thread sealant or tape if required by the system’s operating conditions. Thread the coupling onto the first male fitting until hand-tight, then align the second fitting and thread it into the opposite end of the coupling. Tighten both ends evenly using suitable wrenches to achieve a secure mechanical connection without over-torquing, which can damage threads or compress the galvanised coating.
Usage recommendations
Inspect the coupling regularly for signs of corrosion or thread wear in long-term installations. Use the coupling within the pressure and temperature limits appropriate for galvanized fittings and the overall piping system. Avoid use with fluids or environments that chemically attack galvanized coatings, such as highly acidic or alkaline media.
