Pipe connector adapter Varioterm GW 3/4 x Alu PEX 16x2 nickel Eurocone

Varioterm pipe connector adapter GW 3/4 x Alu PEX 16x2 nickel Eurocone is a mechanical fitting created to join a 3/4-inch threaded (female) connection to 16x2 aluminium-composite PEX pipe. The adapter features a Eurocone interface and a nickel-plated finish, providing corrosion resistance and a consistent mating surface for potable water and heating systems. It is intended for installations where a durable, leak-resistant transition between threaded components and Alu-PEX tubing is required.

Advantages

The adapter provides a secure mechanical seal between a 3/4-inch threaded connection and Alu-PEX 16x2 piping without the need for soldering or adhesive. The nickel finish improves corrosion protection and ensures smooth assembly with metal fittings. A Eurocone connection standardises compatibility with valves and fixtures that accept Eurocone geometry, enabling straightforward integration into domestic water and heating circuits.

Suitable for

• Domestic potable water supply lines
• Residential and commercial heating circuits
• Connections to radiators, valves and manifolds with Eurocone fittings
• Retrofit projects converting threaded components to Alu-PEX piping

Key specifications

• Connection type: 3/4-inch female threaded to Alu-PEX 16x2
• Pipe compatibility: aluminium-composite PEX pipe 16x2 mm
• Finish: nickel-plated surface for enhanced corrosion resistance
• Interface standard: Eurocone geometry for compatible valves and fittings
• Application media: potable water and heating systems

How to use

Ensure both mating surfaces are clean and free of debris before installation. Insert the Alu-PEX 16x2 pipe into the adapter according to the pipe system manufacturer’s recommended insertion depth, and secure using the appropriate crimping or compression method specified for the pipe system. Thread the 3/4-inch female end onto the corresponding male thread of the valve or fitting and tighten to the torque recommended for the connected components. After assembly, perform a pressure test of the installation to verify there are no leaks.

Usage recommendations

Use the adapter only with compatible 16x2 aluminium-composite PEX pipe and Eurocone-compatible fittings. Follow local plumbing codes and the pipe system manufacturer’s instructions for correct crimping, sealing and pressure testing. Avoid overtightening threaded connections to prevent damage to the Eurocone interface or thread seal.
