## Summary description

Unidelta transition fitting PE with female thread, model 601641, designed for connecting 40 mm polyethylene pipe to a 6/4" (1.5") threaded connection. Made for pressure or water supply systems requiring a secure transition between PE piping and threaded fittings. Suitable for plumbing, irrigation and utility connections where a durable, leak-resistant joint is needed.

## Long description

Unidelta transition fitting PE female threaded 40 mm x 6/4" is a polyethylene-to-thread adapter designed to connect 40 mm PE pipe with a 6/4" (1.5") female threaded component. The fitting suits pressure or water supply installations where a reliable mechanical and watertight transition from PE piping to a threaded metal or plastic fitting is required. Constructed for compatibility with standard 40 mm PE pipelines, the component provides a stable interface for plumbing, irrigation and utility connections without requiring special tools beyond common installation equipment.
Advantages
The transition fitting offers corrosion-resistant polyethylene construction and a female threaded interface for secure screw-in connections. Its design ensures a leak-resistant joint when installed according to recommended procedures, while the compact form factor minimizes space requirements at pipe run transitions. The fitting supports mechanical stability under typical domestic and light-commercial water pressure conditions and is suitable for systems where a direct threaded connection is preferred over fusion or compression methods.
Suitable for
Connecting 40 mm PE pipeline to 6/4" (1.5") threaded valves or components
Domestic and small commercial water supply lines
Irrigation systems and garden watering installations
Temporary or permanent utility connections requiring threaded receptors
Key specifications
Material: polyethylene body with integrated female threaded connection
Pipe compatibility: 40 mm PE pressure pipe
Thread type: female 6/4" (1.5") standard thread for threaded fittings and valves
Application: cold water and general pressure piping (non-specific temperature rating)
Connection method: mechanical threaded transition between PE and threaded component
How to use
Prepare the PE pipe by cutting squarely and deburring the end. Slide the pipe into the fitting socket until fully seated according to the fitting's insertion mark or stop. Secure the connection by the manufacturer-recommended method for the polyethylene side (for example, electrofusion, mechanical clamp, or insert and compression as appropriate for the specific fitting design). On the threaded side, apply suitable sealing tape or compound compatible with potable water if required, then tighten the mating male thread hand-tight plus an appropriate wrench turn to achieve a watertight seal. Verify alignment and support the pipeline to avoid undue stress at the transition.
Usage recommendations
Use the fitting only with compatible 40 mm PE pressure piping and standard 6/4" threaded components. Follow local plumbing codes and manufacturer guidance for pressure ratings, installation methods, and any required testing. Avoid exposing the fitting to temperatures or chemicals outside the limits recommended for general polyethylene plumbing materials. After installation, perform a pressure test to check for leaks and ensure mechanical support is provided to prevent bending or tension at the joint.
