## Long description

The Conex transition coupling Oyster nickel-plated 18 mm x 3/4" is a compact plumbing fitting designed to connect metric 18 mm piping to 3/4" imperial threaded fittings. Nickel plating provides surface protection against corrosion and wear while preserving a compact, low-profile form factor suitable for confined installation spaces. The coupling is intended for use in water supply and heating systems where a reliable transition between different pipe standards is required.
Advantages
This nickel-plated transition coupling offers durable corrosion resistance and a smooth exterior finish that eases installation in confined areas. The compact dimensions minimize space requirements and help maintain flow continuity between dissimilar pipe sizes. Its construction is compatible with common plumbing materials and provides a stable mechanical connection for both repair and conversion tasks.
Suitable for
Connecting 18 mm copper or compatible metric pipes to 3/4" threaded fittings
Domestic water supply and central heating installations
Plumbing repairs, retrofits and conversions between metric and imperial systems

How to use
Before installation, ensure both pipe and fitting ends are clean, free of burrs and suitably prepared according to the pipe material.
