## Summary description

Herz reducing coupling P 7020 01 is a compression plumbing fitting that adapts 20x2 mm pipe diameter to 16x2 mm. Designed for joining pipes of different outer diameters, it provides a compact, mechanical transition in water or heating systems. Suitable for use in domestic and commercial installations where reliable, space-saving reduction is required.

## Long description

Herz compression reducing coupling 20x2–16x2 P 7020 01 is a compact mechanical fitting designed to join pipes with outer diameters of 20 mm and 16 mm. Intended for plumbing and heating systems, this reducing coupling creates a sealed transition between different pipe sizes without soldering or glue, using a compression connection principle. The fitting is suitable for potable water and central heating installations where a reliable, neat reduction is required in restricted spaces.
Advantages
The compression design provides a secure mechanical seal that can be installed quickly with common hand tools, minimizing installation time. Its compact form allows use in confined areas and behind fixtures where space is limited. The coupling reduces the need for additional adapters or soldered joints and is compatible with standard 20x2 and 16x2 pipe dimensions, ensuring consistent alignment and flow characteristics in the system.
Suitable for
Reducing pipe runs from 20x2 mm to 16x2 mm in domestic plumbing
Connecting branches in central heating systems
Compact installations behind radiators, sinks, and cabinets
Repairs where a mechanical, non-soldered reduction is preferred
Key specifications
Connection type: compression reducing coupling
Pipe compatibility: 20x2 mm to 16x2 mm outer diameter pipes
Application: water and heating systems
Construction: compact mechanical body for space-saving installation
Installation: requires hand tools for compression tightening
How to use
Prepare the pipe ends by cutting squarely and deburring to ensure full insertion into the coupling. Slide the compression nut and ring (ferrule) onto each pipe, insert the pipe ends into the respective sides of the coupling until they reach the internal stop, then tighten the compression nuts to the recommended torque using appropriate tools. After installation, pressurize the system and check for leaks, retightening slightly if necessary according to manufacturer torque guidance.
Usage recommendations
Use with compatible 20x2 and 16x2 pipes only; ensure pipes are clean and free of scale or damage at the connection points. Do not use for gas installations unless explicitly approved for that purpose. When working on heating systems, follow local codes for system draining and refilling, and verify joint tightness after the first heat-up cycle.
