## Long description

Unidelta transition fitting PE female threaded 20 mm x 3/4" (601621) is a connector designed to join 20 mm polyethylene (PE) pipe to a 3/4" female threaded outlet. It creates a mechanical and hydraulic interface between plastic distribution lines and threaded components such as valves, taps or metal fittings. The fitting is intended for water supply, irrigation and general plumbing installations where a reliable PE-to-thread transition is needed.
Advantages
The fitting offers a compact design that facilitates a secure connection between PE pipe and threaded fixtures without the need for additional adapters. It ensures leak-resistant performance when installed according to recommended procedures and provides corrosion resistance typical of polyethylene-based assemblies. The construction supports straightforward integration into existing pipework and minimizes the number of joints in a system.
Suitable for
 Domestic and commercial water supply lines using 20 mm PE pipe
 Irrigation systems and garden watering installations
 Connecting PE distribution pipe to threaded valves, taps or metal fittings
 General plumbing applications requiring a PE-to-3/4" female threaded transition
Key specifications
 Connection A: for 20 mm polyethylene (PE) pipe
 Connection B: 3/4" female threaded outlet
 Function: transition fitting for joining plastic pipe to threaded components
 Typical applications: potable water supply, irrigation and general plumbing
 Material characteristics: plastic body compatible with PE systems and threaded metal/plastic fittings
How to use
Prepare the 20 mm PE pipe by cutting it square and deburring the end to ensure a smooth insertion. Insert the pipe into the fitting until it seats fully according to the manufacturer's depth marking or recommendation. Tighten the threaded 3/4" connection to the mating component by hand and then secure with a wrench to the torque appropriate for the mating material, taking care not to over-tighten plastic threads. If the fitting uses an internal gasket or sealing element, verify its correct position before assembly. Pressure-test the assembled connection following local plumbing standards to confirm there are no leaks.
Usage recommendations
Use compatible PE pipe and ensure all mating threaded components are rated for the same fluid and pressure conditions. Avoid excessive mechanical stress at the joint and support adjacent pipe runs to reduce strain. Replace any sealing elements that show wear or damage during maintenance.
