Reducer Tee Unidelta 40 x 32 x 40 mm PE pipe fitting (model 603140)

The Unidelta reducer tee 40 x 32 x 40 mm is a polyethylene (PE) pipe fitting engineered to join three pipeline branches where the central outlet is reduced. Designed for use in PE systems with 40 mm and 32 mm outer diameters, this fitting allows a main run to continue while creating a reduced-diameter branch for distribution or connection to smaller-diameter pipework. It is suitable for water supply, irrigation and drainage networks and for installations that require compatible material performance and leak-resistant joints when using PE piping.

Advantages

The reducer tee is manufactured from PE for chemical resistance, flexibility and long-term durability in buried or exposed installations. Its geometry provides a smooth transition between diameters, minimizing hydraulic disturbances at the branch point. The fitting is compatible with standard connection methods for PE piping and allows for reliable, low-maintenance joints when installed according to industry practice.

Suitable for

• Water distribution mains with a branch to smaller-diameter service lines
• Irrigation systems where a reduced outlet is needed for laterals or drippers
• Drainage or stormwater networks requiring a branch of different diameter

Key specifications

• Material: polyethylene (PE)
• Connection configuration: tee with reduced central outlet
• Applicable outer diameters: run outlets 40 mm, reduced outlet 32 mm
• Typical applications: pressure and non-pressure PE piping systems
• Intended use environment: buried pipelines, irrigation lines, and above-ground installations where PE is suitable

How to use

Install the reducer tee in accordance with standard PE fitting procedures. Prepare pipe ends by cutting square, removing burrs and checking for correct outer diameter. Use the appropriate joining method for PE (electrofusion or mechanical fittings) compatible with the tee and the pipe sizes involved. Ensure alignment and correct insertion depths, follow heating or torque specifications if using electrofusion or compression connections, and allow recommended cooling or settling time before pressurizing the system.

Usage recommendations

Verify material compatibility with the piping system and follow applicable local codes and manufacturer instructions for PE jointing. Avoid mechanical stresses at the joint by providing adequate pipe support and bedding. For pressure applications, perform pressure testing after installation according to industry standards.
