## Summary description

Perfexim brass reduction coupling with external (GW) connection 1/2 x 3/4" and chromed finish. Designed to connect pipes or fittings with different thread sizes, it provides a durable, corrosion-resistant mechanical joint for plumbing installations, radiators, and domestic water systems where a change of thread diameter is required.

## Long description

Perfexim brass reduction coupling GW 1/2 x 3/4" chromed is a threaded reducer designed to join plumbing components with different external thread diameters. Made of brass with a chromed finish, the coupling provides a reliable mechanical connection for water supply systems, radiator installations, and general household plumbing where a transition between 1/2" and 3/4" external threads is required.
Advantages
The brass construction ensures mechanical strength and good resistance to corrosion in typical domestic water environments, while the chromed surface improves wear resistance and provides a smooth, easy-to-clean exterior. Threaded connections allow quick assembly and disassembly without soldering or special tools, making the fitting suitable for repairs and modifications. The compact design minimises the space required at pipe junctions.
Suitable for
 Connecting pipes or fittings with 1/2" and 3/4" external threads
 Domestic cold and hot water supply systems
 Radiator inlet/outlet connections and heating circuit adaptations
 Plumbing repairs, service valves, and temporary installations
Key specifications
 Material: brass with chromed finish
 Type of connection: external threaded reducer (GW)
 Thread sizes: 1/2" x 3/4" (external threads)
 Application: potable water and heating systems
 Surface: polished chrome plating for corrosion resistance and easy cleaning
How to use
Ensure both mating threads are clean and free of debris or damaged threads before installation. Apply an appropriate sealing method for threaded joints (e.g., PTFE tape or approved thread sealant) to the male thread. Hand-tighten the coupling onto the mating thread, then finish tightening with a suitable wrench until a secure, leak-free connection is achieved; avoid excessive torque to prevent thread damage. After assembly, pressurise the system and inspect for leaks, retightening if necessary.
Usage recommendations
Use compatible thread sealants and avoid overtightening to preserve the chromed surface and maintain thread integrity. For systems carrying potable water, select sealants certified for drinking water contact. When used in heating systems, perform regular inspections to detect early signs of corrosion or loosening.
