Transition fitting Unidelta PE female thread 25 mm x 3/4" (601625)

Unidelta transition fitting 25 mm x 3/4" (model 601625) is a polyethylene (PE) connector designed to join a 25 mm PE pipe to a standard 3/4" female threaded fixture. The fitting provides a watertight connection between flexible or rigid PE distribution lines and metal or plastic threaded devices, making it suitable for irrigation systems, garden taps, outdoor water supply, and various plumbing repairs where a secure transition from PE piping to threaded components is needed.

Advantages

This Unidelta transition fitting is made of durable polyethylene material that resists corrosion and chemical exposure common in outdoor and irrigation use. The 3/4" female threaded outlet ensures compatibility with a wide range of standard threaded fittings and valves. The design allows for a straightforward connection to 25 mm PE pipe, offering a compact and reliable solution for converting from PE pipework to threaded fittings without the need for complex adapters.

Suitable for

• Irrigation systems and dripline connections
• Garden faucets and outdoor water points
• Temporary or permanent plumbing repairs on PE lines
• Connecting PE distribution pipes to valves, meters, or hose adapters

Key specifications

• Material: polyethylene (PE)
• Pipe connection diameter: 25 mm
• Outlet type: 3/4" female thread
• Intended use: transition between PE pipe and threaded fittings
• Typical installation environment: irrigation, outdoor water supply, garden plumbing

How to use

Prepare the 25 mm PE pipe by cutting it squarely and removing any burrs. Insert the pipe end into the fitting according to the manufacturer's recommended insertion depth and secure the connection using the appropriate compression or mechanical method for the fitting design. Once the PE pipe is fixed, thread the 3/4" male component (valve, adapter, or connector) into the female outlet hand-tight, then finish with a suitable wrench to achieve a leak-free joint without over-tightening. Verify alignment and test the assembled connection under operating pressure before leaving it in service.

Usage recommendations

Use compatible 25 mm PE pipe and ensure that external loads or stresses on the joint are minimized. For long-term installations, consider protecting the fitting from direct UV exposure and extreme mechanical impacts. When connecting metal components, use appropriate sealant or PTFE tape on the male thread to improve sealing performance and prevent galvanic contact where dissimilar metals are present.
