## Summary description

Suitable for water supply and irrigation systems where a transition from PE tubing to standard threaded plumbing is required.

## Long description

ALFA RK pipe fitting PE female thread 20×3/4" A-U, model 601621 is a compact connector that allows a secure transition between 20 mm polyethylene (PE) pipe and a standard 3/4" female threaded fitting. Designed for potable water and irrigation systems, the fitting provides a reliable mechanical connection where a PE pipeline must interface with threaded valves, taps or appliances. The body is shaped to accept PE pipe and includes the female threaded outlet for conventional plumbing attachments.
Advantages
The fitting offers a direct and space-efficient conversion from PE pipe to a 3/4" female thread without additional adapters. Its geometry supports straightforward installation with common tools and ensures leak-resistant performance when installed according to recommended procedures. The product is suitable for outdoor and indoor water distribution applications where a durable transition to threaded components is required.
Suitable for
 Connection of 20 mm PE pipelines to 3/4" threaded valves and taps
 Irrigation systems requiring a threaded outlet for accessories or controllers
 Domestic and light commercial water supply installations
Key specifications
 PE pipe connection diameter: 20 mm
 Thread type and size: female thread, 3/4"
 Material: polyethylene-compatible fitting body (designed for use with PE pipes)
 Application: water supply and irrigation systems
 Connection method: mechanical transition from PE pipe to threaded outlet
How to use
Cut the PE pipe square and remove any burrs. Insert the pipe into the fitting until it reaches the stop and secure it according to the fitting's assembly method (for example, with an appropriate compression or insertion technique compatible with ALFA RK PE fittings). Ensure the threaded outlet mates correctly with the counterpart connection and tighten to the recommended torque for 3/4" threaded plumbing to avoid overtightening. After assembly, pressurize the system and inspect the joint for leaks.
Usage recommendations
Use compatible PE pipe of the specified 20 mm nominal size and follow local plumbing codes. Apply plumbing thread sealant or tape to the 3/4" male thread if required by the installation to ensure leak-free performance. Avoid excessive bending near the fitting and protect the joint from prolonged exposure to direct UV if the PE pipe is not UV-stabilized.
