Unidelta transitional fitting PE female threaded 50 mm x 6/4" (601650)

Unidelta transitional fitting PE female threaded 50 mm x 6/4" is a polyethylene-to-thread adapter designed to connect PE pipes with female threaded components. The fitting provides a mechanical and sealed transition between a 50 mm polyethylene pipeline and a 6/4" threaded mating part, enabling integration of PE piping with valves, meters or other threaded fittings in water supply and irrigation systems. Constructed for field installation and repairs, the adapter supports standard PE pipe dimensions and is intended for applications requiring a durable, watertight joint.

Advantages

The Unidelta transitional fitting offers a simple, reliable means to convert between PE pipe and threaded connections without specialized tools. Its polyethylene body resists corrosion and common soil chemicals, while the threaded interface ensures compatibility with standard 6/4" fittings. The design minimizes leak risk when installed according to recommended procedures and is suitable for both new installations and maintenance work.

Suitable for

• Domestic and commercial water supply pipelines
• Irrigation and agricultural systems
• Connection to valves, meters and threaded fittings
• On-site repair and retrofit of PE pipe networks

Key specifications

• Material: polyethylene body suitable for PE piping systems
• Connection types: PE pipe end to female threaded 6/4" interface
• Pipe nominal diameter: 50 mm
• Intended media: potable and non-potable water (system-dependent)
• Typical installation: mechanical compression or fusion-compatible PE end (consult installation method)

How to use

Prepare the pipe end by cutting squarely and removing burrs and debris. Fit the PE pipe onto the fitting end following the manufacturer’s assembly instructions for the specific connection method (mechanical compression or compatible fusion practice). Tighten the female threaded side to the mating 6/4" male thread, using appropriate sealing tape or gasket if required by the threaded component’s specifications. After assembly, inspect the joint and perform a pressure test where applicable to verify watertightness.

Usage recommendations

Follow local regulations and Unidelta installation guidance for pressure ratings and approved assembly methods. Use appropriate thread sealing materials on the 6/4" connection if the mating part requires it, and avoid exposing the polyethylene body to direct flame or solvents during installation. For long-term performance, ensure compatibility of system media and perform periodic inspections for mechanical stress or wear.
