Reducing Tee Unidelta PE threaded 25 mm × 3/4" × 25 mm, model 603525

Unidelta reducing tee in PE material with a threaded centre connection: 25 mm × 3/4" × 25 mm (model 603525). This reducing tee is made from polyethylene (PE) and features two socket ends for 25 mm pipe connections and a central threaded port sized at 3/4". It is intended for use where a reduced, threaded branch is required in potable water, irrigation and general piping installations. The central threaded connection allows direct mounting of valves, fittings or meters while the PE sockets provide a secure mechanical or electrofusion joint to compatible polyethylene pipes.

Advantages

The fitting combines corrosion-resistant PE construction with a threaded centre that enables easy installation of brass or plastic valves and accessories. Its reduced threaded branch offers a compact solution for integrating meters or service outlets without compromising the continuity of the main pipeline. The smooth internal profiles minimise flow disturbance, and the material choice ensures chemical resistance suitable for water supply and many irrigation applications.

Suitable for

• Potable water distribution networks
• Irrigation systems for gardens, greenhouses and agriculture
• Plumbing systems requiring a reduced threaded branch for valves or fittings
• Connections where a durable, corrosion-resistant PE fitting is preferred

Key specifications

• Material: polyethylene (PE)
• End connections: two socket ends for 25 mm pipe
• Branch connection: central threaded port 3/4" (female/male as per model design)
• Type: reducing tee with threaded branch
• Applications: potable water, irrigation, general piping

How to use

Prepare the 25 mm PE pipes by cutting square and deburring the ends. Join the socket ends to the main pipeline by the appropriate method for the PE material — mechanical compression, butt fusion, or electrofusion — following the installation standards for the chosen technique. Install the required valve, fitting or meter into the 3/4" threaded branch using suitable sealing tape or thread sealant compatible with potable water. Ensure all threaded connections are tightened to the manufacturer-recommended torque and perform pressure testing of the assembled system according to applicable codes.

Usage recommendations

For long-term performance, avoid exposing the fitting to prolonged UV radiation without protection, and use compatible PE joining methods and potable-water-approved thread sealants. Confirm the pressure and temperature limits of the system components before installation and follow local regulations for potable water and irrigation installations.
