Reduction Tee SiGMA-Li TR6350 polypropylene (PP) 63×50×63 mm

SiGMA-Li TR6350 is a polypropylene (PP) reduction tee for piping systems with nominal dimensions 63×50×63 mm. The fitting connects three pipe runs with a reduced middle outlet, allowing diversion or distribution of liquids and gases in plumbing, irrigation and general fluid-handling installations. Made of polypropylene, the tee is designed for compatibility with PP piping and solvent-weld or heat-fusion joining methods commonly used in residential and light commercial systems.

Advantages

The reduction tee offers chemical resistance and low weight characteristic of polypropylene, ensuring durability in contact with common household and irrigation fluids. Its concentric geometry provides predictable flow characteristics and simpler alignment during installation. The fitting’s reduced middle branch enables a smooth change in pipe diameter while maintaining structural integrity and minimizing turbulence at the junction.

Suitable for

• Domestic plumbing systems for cold water distribution
• Irrigation mains and branch lines
• Light commercial fluid-handling installations
• Drainage and venting systems compatible with PP fittings

Key specifications

• Material: polypropylene (PP)
• Configuration: reduction tee, three-way junction with reduced middle outlet
• Nominal dimensions: 63 × 50 × 63 mm (main run × branch × run)
• Connection type: designed for PP joining methods (solvent-weld or heat-fusion depending on installation practice)
• Typical applications: cold water, irrigation, non-aggressive fluid conveyance

How to use

Prepare pipe ends by cutting square and removing burrs before joining. Ensure mating surfaces are clean and free of contaminants. Install the reduction tee using the appropriate PP joining method for your system — solvent welding or heat fusion — following the tool and adhesive manufacturers’ instructions. Verify correct alignment of the branch and main runs prior to curing or cooling. After joining, test the system at the recommended pressure to confirm leak-free performance.

Usage recommendations

Do not use the polypropylene reduction tee with fluids or gases above the temperature and pressure limits established for PP piping in your local codes. Avoid exposure to strong oxidizing chemicals or solvents that can degrade polypropylene. For pressurized systems, follow applicable installation standards and perform pressure tests after assembly. When in doubt about chemical compatibility or operating conditions, consult material data sheets or a qualified installer.
