## Summary description

Unidelta transition fitting, model 601620, designed to connect PE (polyethylene) pipe of 20 mm diameter to a 1/2" female threaded metal or plastic fitting. The adapter provides a reliable mechanical and pressure-tight connection between PE tubing and threaded components, suitable for plumbing, irrigation, and water supply systems where a change from socket pipe to threaded fittings is required.

## Long description

Unidelta transition fitting PE female thread 20 mm x 1/2" (601620) is an adapter designed to join 20 mm polyethylene (PE) pipes to 1/2" female threaded fittings. The fitting creates a mechanical, pressure-resistant connection between smooth PE tubing and threaded metal or plastic components, enabling integration of PE distribution lines with conventional threaded valves, taps and fixtures in plumbing, irrigation and water supply systems.
Advantages
The fitting provides a compact and robust transition from PE pipe to a 1/2" female thread without the need for specialized tools. Its construction ensures a leak-resistant joint under normal operating pressures, and compatibility with both metal and plastic threaded components increases installation flexibility. The product is lightweight and corrosion-resistant due to the use of polymer materials in its PE connection area, while the threaded interface allows secure mechanical attachment to existing fittings.
Suitable for
Connecting 20 mm PE distribution pipes to 1/2" threaded valves and taps
Irrigation manifolds and garden watering systems
Domestic cold water supply lines and outdoor plumbing
Retrofit or extension of existing threaded plumbing fixtures
Key specifications
Pipe connection diameter: 20 mm for PE pipe
Thread type: 1/2" female threaded connection compatible with standard 1/2" fittings
Material interface: polymer for PE connection and threaded portion suitable for metal/plastic fittings
Application: potable and non-potable water distribution, irrigation
Operating environment: indoor and outdoor installations where temperature and pressure fall within material limits
How to use
Prepare the 20 mm PE pipe by cutting it square and deburring the end. Insert the pipe into the PE side of the transition fitting until it reaches the internal stop; depending on design, secure the pipe with the recommended method (push-fit, compression ring or clamp as applicable). Thread the 1/2" female end onto the corresponding male threaded fitting by hand, then tighten to a secure fit using an appropriate tool without over-torquing. Verify alignment and perform a pressure/leak test according to system requirements before putting the line into regular service.
Usage recommendations
Ensure compatibility of thread type and sealing method with the mating fitting; use suitable thread sealant or tape if required. Avoid excessive bending or mechanical stress at the connection point. Follow local plumbing codes and manufacturer guidelines for operating pressures and temperatures.
