Transitional PE Female Thread Connector Unidelta 25 mm x 1/2" (601624)

The Unidelta Transitional PE Female Thread Connector 25 mm x 1/2" (model 601624) is a mechanical fitting designed to join polyethylene (PE) pipes with a 25 mm socket to a 1/2" female threaded metal connection. It creates a secure transition point between plastic distribution pipe and threaded metal fittings or valves, providing a durable junction for water distribution, irrigation systems and low-pressure plumbing applications.

Advantages

This transitional connector offers a reliable mechanical seal between PE piping and threaded components without the need for solvent welding or complex tools. Constructed to withstand typical pressures encountered in domestic and agricultural water systems, it reduces potential leak points by ensuring a tight fit and consistent thread engagement. The design allows for quick installation and later disassembly for maintenance or replacement of connected valves or fittings.

Suitable for

• Domestic water distribution lines using 25 mm PE pipe
• Irrigation systems and garden watering installations
• Connections to threaded valves, taps or metal fittings sized to 1/2"
• Low-pressure plumbing circuits where transition from PE to metal is required

Key specifications

• PE socket nominal diameter: 25 mm compatible with standard PE pipe
• Thread type: female thread sized to 1/2" (for mating with 1/2" male fittings)
• Material combination: plastic body suited for mechanical connection to PE and metal threaded interface
• Application pressure range: suitable for typical low- to medium-pressure water distribution systems (refer to system design for exact limits)
• Typical uses: potable water distribution, irrigation and general low-pressure plumbing

How to use

Prepare the PE pipe by cutting a clean, square end and deburring the inner and outer edges. Slide the connector onto the pipe until the socket seats fully, observing any insertion depth markings if present. Tighten the mechanical components according to the manufacturer's recommended procedure—ensure the threaded metal fitting or valve is engaged to the female thread and tightened to an appropriate torque for a leak-free seal. Check alignment to avoid cross-threading and verify the joint visually before pressurizing the system.

Usage recommendations

Use with compatible 25 mm PE pipe and standard 1/2" threaded metal fittings. Do not exceed the pressure and temperature limits of the connected piping system; follow local plumbing codes. For long-term installations, periodically inspect threaded transitions for tightness and signs of wear or corrosion on metal fittings. When in doubt, consult a qualified plumber for correct assembly and torque settings.
