KAN-therm reducing tee PP 40x20x40 mm, model 04105040

The KAN-therm reducing tee PP 40x20x40 mm is a polypropylene fitting designed for connecting a 20 mm branch to two 40 mm main runs with a right-angled reduction in diameter. Intended for use in plastic piping systems, this fitting provides a compact connection point for potable water, heating and plumbing installations where polypropylene components are specified. The part is compatible with fusion or solvent-welding methods appropriate for PP systems and is shaped to integrate into manifolds and branch networks without compromising flow paths.

Advantages

This reducing tee offers chemical resistance and corrosion-free service typical of polypropylene materials, ensuring long-term durability in contact with potable water and heating media. Its dimensional design enables a stable, low-profile junction between different pipe diameters, helping to reduce pressure losses across the branch point. The fitting is lightweight, easy to handle on site, and suitable for standard PP joining techniques used in professional plumbing and HVAC installations.

Suitable for

• Domestic and commercial potable water distribution systems
• Underfloor heating and heating circuit manifolds
• Plumbing branch connections and manifold feed lines
• Renovation projects involving replacement of mixed-diameter polypropylene pipes

Key specifications

• Material: polypropylene (PP)
• Connection configuration: reducing tee (side branch at right angle)
• Pipe diameters: main runs 40 mm, branch 20 mm
• Suitable joining methods: PP fusion/solvent welding or other PP-compatible techniques
• Application media: potable water, heating fluids
• Typical use temperature range: suitable for common heating and sanitary system temperatures when used according to system specifications

How to use

Prepare pipe ends by cutting square and removing burrs, then clean surfaces according to the chosen joining method for polypropylene. Insert pipes fully into the fitting and perform fusion or solvent-welding in accordance with the manufacturer’s instructions and applicable installation standards. Ensure correct alignment of the 20 mm branch relative to the 40 mm mains and allow sufficient cooling or curing time before reintroducing pressure to the system. Pressure-test the completed installation following local codes and project requirements.

Usage recommendations

Use compatible polypropylene pipes and follow recommended fusion or solvent-welding procedures. Avoid mechanical stress at the joint by supporting nearby pipe runs and manifolds; verify temperature and pressure limits of the overall system to ensure the fitting's suitability for the intended application.
