16mm x 15mm Compression Reducing Coupling (Brass) – CORC-1615

The COMP CORC-1615 is a 16mm x 15mm reducing coupling used to connect pipes of slightly different diameters in compression systems. Ideal for mixed-standard plumbing installations (e.g., combining European 16mm with UK 15mm pipework), this fitting provides a secure mechanical seal without soldering. Made from DZR brass, it is corrosion-resistant and suitable for water, heating, and low-pressure gas systems.

• Adapts 16mm pipe to 15mm systems, commonly used in mixed-standard installations
• Mechanical compression seal – no solder or flame required
• Compatible with copper and approved plastic pipes
• Ideal for potable water, central heating, and low-pressure gas
