Unidelta reducing tee PE 32 x 20 x 32 mm pipe fitting, model 603131

Unidelta reducing tee PE 32 x 20 x 32 mm (model 603131) is a polyethylene (PE) pipe fitting designed to create a compact branch with a reduced diameter in PE piping systems. The fitting links two 32 mm lines with a central 20 mm outlet, enabling a straightforward transition between pipe sizes while maintaining line continuity. It is intended for use in non-pressurized and low-pressure water supply, irrigation and landscape distribution networks built with compatible PE pipes.

Advantages

This Unidelta reducing tee is produced from durable polyethylene material that offers resistance to corrosion and many common soil chemicals, ensuring long service life in underground or exposed installations. The design provides a neat, compact branch point that minimizes space requirements and simplifies piping layouts. The fitting enables reliable size reduction without the need for additional adapters when connecting 32 mm main lines to 20 mm branches, supporting efficient installation and reduced leak risk when joined with appropriate connection methods for PE fittings.

Suitable for

• Domestic and small commercial irrigation systems
• Garden and landscape watering networks
• Low-pressure potable water distribution in PE piping networks
• Branching lines in agricultural polyethylene pipe systems

Key specifications

• Material: Polyethylene (PE)
• Connection configuration: Reducing tee, two equal outlets and one reduced branch
• Outlet diameters: 32 mm (main line) and 20 mm (branch)
• Typical application: Water supply and irrigation distribution
• Installation type: In-line branch fitting for PE piping systems

How to use

Select compatible PE pipes of the indicated diameters and prepare pipe ends by cutting square and deburring. Install the reducing tee using the manufacturer-recommended connection method for PE fittings (for example, electrofusion, butt fusion, or compatible mechanical compression fittings), following safe working practices and local installation standards. Ensure correct alignment and heating/pressure parameters if fusion methods are used. After installation, verify joints visually and by pressure testing according to project requirements before commissioning the line.

Usage recommendations

Use this reducing tee with PE pipes of the specified diameters and follow the chosen joining method's instructions to ensure leak-free connections. Avoid exposing the fitting to temperatures or pressures outside standard PE pipe system limits and protect it from prolonged UV exposure if installed above ground.
