PEX-AL-PEX multilayer pipe adapter, Ø20 mm

The PEX-AL-PEX multilayer pipe adapter (connector) Ø20 mm is a reliable fitting designed to create a detachable joint and provide a transition from multilayer (metal-plastic) pipe to a threaded connection in water supply (cold/hot water) and heating systems. The 20 mm diameter is widely used in household distribution lines and in sections with higher flow demand, which is why this connector is commonly installed when connecting manifolds, shut-off valves, filters, pressure reducers, water heaters, metering assemblies, and other system components. It helps build a neat, technically correct connection point—especially when disassembly and servicing are important.

The fitting is made of nickel-plated brass, delivering high mechanical strength and strong corrosion resistance. The nickel plating acts as a protective layer: it reduces oxidation risk, extends service life, and protects against mechanical wear and exposure to aggressive liquids or environments. This makes the connector suitable for high-humidity areas such as bathrooms and kitchens, as well as more demanding applications where humidity and temperature may be higher than normal—steam rooms and saunas. With proper installation, the fitting maintains tightness and stable performance over time.

A key advantage of the Ø20 connector is its easy installation. No specialized equipment is required: you simply prepare the pipe and tighten the connection with a standard adjustable wrench, significantly speeding up assembly and making it convenient for repairs or upgrades of existing pipework. For maximum sealing on the threaded side, it is recommended to use suitable sealing materials (selected according to thread type and operating conditions). The detachable design is service-friendly: if needed, you can replace a valve, remove a section, or inspect the joint without dismantling the entire line.

The connector is engineered for real-world system conditions: an operating temperature range of -20°C to +90°C allows use in various climates and in spaces without permanent heating. A nominal pressure rating of up to 10 bar ensures safe operation even in higher-pressure systems—relevant for private houses, cottages, and installations with pumping equipment.

The Ø20 adapter is also commonly used in underfloor heating projects, pipe runs embedded in screed, and tiled areas. It provides a secure transition between the multilayer line and threaded components while keeping the connection compact and tidy. It is a practical choice for anyone aiming to build a durable system with minimal risk.

Key benefits:

transition from PEX-AL-PEX Ø20 mm pipe to a threaded connection;

nickel-plated brass for enhanced corrosion and wear resistance;

installation with a standard wrench—no soldering/welding/press tools;

suitable for heating and cold/hot water, including humid areas (bathrooms/saunas);

operating parameters: -20…+90°C, up to 10 bar.

If you need a dependable Ø20 mm multilayer pipe adapter that is easy to install, long-lasting, and provides a leak-tight detachable joint, this nickel-plated brass connector is an optimal solution.
