Compression Connector Varioterm PEX 16/2 x M22/1.5, black structured finish

Compression connector Varioterm PEX 16/2 x M22/1.5 in a black structured finish is a mechanical fitting designed to connect 16 mm PEX tubing (2.0 mm wall thickness) to a threaded M22 fitting. The connector uses a compression mechanism to create a watertight joint without soldering or special tools, providing a practical solution for plumbing and heating installations where a secure transition from PEX pipe to a threaded fixture is required. The black structured finish offers a discreet, durable appearance for visible installations.

Advantages

The compression design delivers a reliable, leak-resistant connection suitable for potable water and heating systems when installed according to applicable standards. Installation does not require heat or adhesives, enabling quick assembly and reduced installation time. The black structured finish resists minor surface wear and conceals fingerprints and smudges, maintaining a uniform look on exposed piping. The connector is compatible with standard 16 mm PEX pipe (2.0 mm wall), ensuring predictable performance in common domestic and light commercial applications.

Suitable for

• Connecting 16 mm PEX (2.0 mm wall) tubing to threaded M22 fittings
• Domestic potable water supply lines
• Underfloor heating manifolds and radiator connections with compatible threads
• Repair or retrofit work where soldering or brazing is impractical

Key specifications

• Pipe compatibility: 16 mm PEX with 2.0 mm wall thickness
• Thread connection: M22 with 1.5 mm pitch (female/male threaded mating as required)
• Connection type: compression fitting
• Finish: black structured surface
• Application: plumbing and heating systems—cold and hot water circuits

How to use

Prepare the PEX tube by cutting squarely and deburring the end to ensure a clean face. Slide the compression nut and ferrule onto the PEX pipe, insert the pipe end fully into the connector body until it seats, then hand-tighten the compression nut onto the threaded M22 component. Complete assembly by tightening to the manufacturer-recommended torque or until a firm, leak-free joint is achieved using appropriate spanners. After installation, pressurize the system and inspect the joint for leaks before backfilling or concealing the connection.

Usage recommendations

Use with PEX tubing of the specified dimension and wall thickness only, and employ compatible M22-threaded fittings. Follow local plumbing codes and standard installation practices, and verify torque and sealing where required. For installations exposed to freezing conditions or mechanical strain, provide appropriate insulation and strain relief. Periodic inspection after initial pressurization is advised to confirm long-term integrity.
