Reducing Tee Unidelta PE threaded GZ PE 40 mm x 5/4" x 40 mm (model 603540)

Unidelta reducing tee PE threaded GZ PE 40 mm x 5/4" x 40 mm (model 603540) is a polyethylene (PE) branch fitting designed to join three sections of PE pipeline while providing a reduced central outlet with a 5/4" threaded connection. The component is intended for potable and non-potable water distribution, irrigation lines and general fluid conveyance where a threaded transition is required for valves, meters or other threaded accessories. Construction in PE ensures corrosion resistance and compatibility with common PE pipe systems.

Advantages

The reducing tee offers a reliable threaded GZ interface that simplifies connection to standard 5/4" threaded fittings without the need for additional adapters. Being manufactured from PE, the fitting provides chemical resistance, lightweight handling and resistance to external corrosion. The symmetric 40 mm side runs maintain full bore flow while the reduced central branch enables integration of smaller threaded components. The product is compatible with common PE joining methods and is suitable for both above-ground and buried installations when installed according to local codes.

Suitable for

• Domestic and municipal water distribution networks requiring a threaded branch
• Irrigation systems for gardens, parks and agricultural plots
• Connections to threaded valves, meters or pressure regulation devices
• Retrofit installations where a transition from PE pipe to threaded fitting is needed

Key specifications

• Material: polyethylene (PE)
• Configuration: 40 mm — 5/4" — 40 mm reducing tee
• Central outlet: 5/4" threaded (GZ) connection for compatible threaded components
• Side connections: 40 mm PE socket ends suitable for PE pipe joining methods
• Typical applications: water supply, irrigation and general fluid conveyance

How to use

Prepare the mating PE pipes by cutting squarely and cleaning the pipe ends. Install the tee using the appropriate PE joining method for the side connections (electrofusion, butt fusion or mechanical compression couplers), following equipment manufacturer instructions and local installation standards. Apply thread sealing (e.g., PTFE tape or approved sealant) to the 5/4" threaded male/female threads as required before attaching valves or other threaded fittings to ensure a leak-free joint. Verify alignment and allow any fusion joints to cool or cure fully prior to pressurizing the system.

Usage recommendations

Use compatible PE joining techniques and approved thread sealants for the 5/4" connection. Confirm pressure ratings and chemical compatibility for the specific application. For buried installations maintain recommended burial depth and backfill practices, and inspect joints periodically for signs of wear or leakage.
