## Long description

Unidelta transitional PE fitting 20 mm x 3/4" — model 601521 is a connector designed to join 20 mm polyethylene (PE) pipe to a standard 3/4" threaded outlet. The fitting provides a reliable mechanical transition between flexible PE piping and threaded fixtures used in domestic water supply, irrigation lines, and outdoor plumbing. Its design enables straightforward integration into existing systems for repairs, retrofits, or new installations where a secure threaded connection is required.
Advantages
The fitting ensures a tight, leak-resistant connection between PE pipe and 3/4" threaded components without the need for complex adapters. Constructed to accommodate the flexibility of PE piping, it reduces the risk of stress at the joint and simplifies installation. Its compact form factor and standard thread sizing make the part compatible with a wide range of valves, taps, and fixtures commonly used in water supply and irrigation applications.
Suitable for
Connecting 20 mm PE supply lines to 3/4" threaded taps and valves
Residential and commercial irrigation systems

Key specifications
Materials compatible with polyethylene pipe systems
Inlet diameter: 20 mm (for PE pipe connection)
Outlet thread: 3/4" standard threaded connection
Designed for water supply and irrigation use

How to use
Prepare the 20 mm PE pipe by cutting it squarely and ensuring the pipe end is free of burrs and debris. Insert the pipe into the PE side of the fitting according to the manufacturer’s insertion depth and secure it as recommended for the specific fitting type (for example, by using the supplied compression mechanism or clamping system). Screw the 3/4" threaded outlet into the mating fixture, applying appropriate thread sealant or PTFE tape if required by the installation standards. Check the assembled joint for correct alignment and test the connection under working pressure to verify there are no leaks.
Usage recommendations
Use compatible sealing materials on the 3/4" threads and follow local plumbing codes. Avoid excessive bending or axial loads at the joint; support adjacent piping to reduce stress. For long-term reliability in outdoor installations, protect the fitting from prolonged UV exposure and inspect periodicallly for signs of wear or leakage.
