Product information

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
  • Tight or restricted installation spaces where a low-profile coupling is needed

Key specifications

  • Connection sizes: 18 mm (metric) to 3/4" (imperial)
  • Surface finish: nickel-plated for enhanced corrosion resistance
  • Function: transition coupling for joining different pipe standards
  • Form factor: compact, low-profile coupling suitable for constrained spaces

How to use

Before installation, ensure both pipe and fitting ends are clean, free of burrs and suitably prepared according to the pipe material. Slip the coupling onto the 18 mm pipe or insert to the specified depth and engage the 3/4" threaded fitting, ensuring proper thread engagement and alignment. Tighten to the recommended torque for the materials used, and check for leaks after pressurizing the system. Follow any local plumbing codes and the installation practices appropriate for copper, brass or compatible materials.

Usage recommendations

Use the Conex transition coupling Oyster nickel-plated 18 mm x 3/4" in potable water, heating and similar systems where metric-to-imperial conversion is required. Verify compatibility with pipe material and operating temperatures, and perform a pressure test after installation to confirm a leak-free connection.
