Transition for metal-plastic pipe PEX-AL-PEX F 16 mm.x 1/2

The PEX-AL-PEX 16 mm × 1/2" F adapter (connector) is a detachable compression fitting used to reliably connect Ø16 mm multilayer (metal-plastic) pipe to system components and equipment with a 1/2" male thread. It is widely used in heating and cold/hot water supply systems, in manifold cabinets, and for connecting radiators, towel warmers, mixing assemblies, filters, water meters, pressure reducers, and ball valves. The adapter provides a clean “pipe → thread” transition without extra adapters, keeping the joint compact and easy to service.

Made of nickel-plated brass, the fitting is designed for long-term operation in humid areas and demanding conditions. The nickel plating protects the metal against corrosion, mechanical wear, and aggressive environments, helping the connection remain neat and dependable even with temperature and humidity fluctuations. This makes it a solid choice not only for apartments and private houses, but also for high-humidity locations such as bathrooms, kitchens, steam rooms, and saunas where connection quality is critical.

The fitting features a compression design: on the pipe side, sealing is achieved by a union nut and compression ring that secure the multilayer pipe without soldering, welding, or press tools. On the connection side, it has a 1/2" female thread (F)—a standard size compatible with most plumbing and heating components. The detachable format is especially convenient because the joint can be disassembled for inspection or valve replacement without dismantling the entire line.

Installation is straightforward and suitable for both professionals and DIY assembly. In most cases, you only need an adjustable wrench and proper pipe preparation: a clean square cut, calibration, and deburring/chamfering. Then the pipe is pushed onto the fitting until it stops and the nut is tightened (while holding the fitting body with a second wrench). For the threaded side, it is recommended to use appropriate sealing materials to ensure long-term leak-tight performance.

The adapter is engineered for real operating conditions: -20°C to +90°C working temperature and up to 10 bar nominal pressure. These specifications make it suitable for most residential water and heating systems, including runs in screed and near finished surfaces (such as tiled areas) where reliability and leak prevention are essential.

If you need a Ø16 mm multilayer pipe adapter with a 1/2" female thread that is easy to install, corrosion-resistant, and suitable for hot/cold water and heating, this PEX-AL-PEX compression connector is a practical, long-lasting solution.
