Compression Adapter Varioterm PEX 16/2 to M22×1.5, matte black

Compression adapter Varioterm PEX 16/2 to M22×1.5 in matte black is a plumbing fitting designed to join 16 mm PEX pipe (2.0 mm wall) to a male M22×1.5 threaded connection. Manufactured for use where flexible PEX piping interfaces with threaded valves, hoses or fixtures, this adapter provides a compact transition between PEX tubing and standard M22×1.5 male fittings. The matte black finish offers a discrete look suitable for visible installations in domestic and light commercial water and heating systems.

Advantages

The adapter uses a compression-style connection on the PEX side that ensures a reliable, leak-resistant joint without the need for soldering or adhesive. The threaded M22×1.5 end provides a standard mechanical interface compatible with many valves and connectors. Its construction is intended to resist corrosion and maintain sealing performance under normal domestic water and heating conditions. The compact form factor simplifies installation in confined spaces and the matte black surface reduces visible reflections where appearance matters.

Suitable for

• Connecting 16/2 PEX tubing to male M22×1.5 threaded valves or fittings
• Plumbing repairs and retrofits in residential water supply lines
• Transition fittings in heating circuits and radiator connections
• Installations where a low-profile, matte black finish is preferred

Key specifications

• Pipe compatibility: 16 mm PEX with 2.0 mm wall thickness
• Thread type: male M22×1.5
• Connection method: compression connection on PEX side, threaded on the opposite side
• Finish: matte black
• Typical applications: potable water and heating systems in residential and light commercial settings

How to use

Prepare the PEX tubing by cutting it squarely and ensuring the end is free from burrs and debris. Insert the PEX tube fully into the compression fitting until it seats against the internal stop, then tighten the compression nut according to the manufacturer's recommended torque ranges or until a secure, leak-free joint is achieved. Thread the M22×1.5 male end into the corresponding female fitting or valve and tighten to the specified torque. After installation, perform a pressure test of the system to verify leak-tight performance and check all joints visually.

Usage recommendations

Use appropriate PEX installation tools and follow local plumbing codes. Do not overtighten threaded connections; use a torque wrench or manufacturer guidance when available. Inspect sealing surfaces and replace any damaged parts before installation. For installations in visible areas, ensure the matte black finish is matched with surrounding fixtures if aesthetics are important.
