PEX-AL-PEX multilayer pipe adapter, Ø26 mm

The PEX-AL-PEX multilayer pipe adapter (connector) Ø26 mm is a robust and practical fitting designed to transition from multilayer (metal-plastic) pipe to a threaded connection in heating and water supply systems. The 26 mm diameter is typically used on main lines and in higher-flow nodes, which is why this connector is particularly in demand for boiler-room equipment connections, manifold groups, water heaters, pump modules, filters, metering assemblies, shut-off valves, and distribution points. It supports a clean, technically correct installation by providing a secure joint between the pipe and threaded components without unnecessary extra adapters or complex procedures.

The fitting is made of nickel-plated brass, delivering two key benefits: high mechanical strength and strong corrosion resistance. The nickel plating protects the surface from oxidation, mechanical wear, and exposure to aggressive liquids or environments. As a result, the adapter is well-suited for long-term use in real operating conditions—from standard apartment and house installations to high-humidity areas. It can be used in bathrooms and kitchens, as well as in steam rooms and saunas where the reliability of each connection and material durability are critical.

One of the main advantages of the Ø26 connector is its detachable design and straightforward installation. No soldering, welding, or press tools are required—assembly can be completed using a standard adjustable wrench. This speeds up installation, simplifies repairs, and makes the fitting convenient for upgrading existing lines when you need a quick connection to a threaded node. For maximum sealing on the threaded side, it is recommended to use suitable sealing materials (selected according to thread type and operating conditions). The ability to disassemble the joint is a major plus: during service you can remove a section, replace a valve, or inspect the connection without dismantling the entire system.

The connector is engineered for stable performance across a wide range of conditions: an operating temperature range of -20°C to +90°C allows use in various climates, including unheated spaces during transitional seasons. A nominal pressure rating of up to 10 bar ensures confident operation even in systems with higher pressure and pumping equipment. This makes the fitting suitable for private houses, cottages, technical rooms, and critical nodes where strength and safety matter.

The Ø26 adapter is also relevant for heating circuits, distribution lines, and sections where the pipe runs in screed or near finished surfaces—especially in underfloor heating projects and tiled areas. It provides a secure transition from the multilayer main line to threaded system components while keeping the node compact and serviceable.

Key benefits of the PEX-AL-PEX Ø26 adapter:

reliable transition from Ø26 mm multilayer pipe to a threaded connection;

nickel-plated brass for high corrosion and wear resistance;

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

suitable for heating and cold/hot water, including humid areas and steam rooms/saunas;

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

If you are looking for a durable Ø26 mm multilayer pipe adapter that provides a leak-tight detachable connection and is suitable for demanding nodes, this nickel-plated brass connector is a dependable foundation for your system.
