Reducing Tee SiGMA-Li TR3220, polypropylene (PP) 32×20×32 mm

SiGMA-Li TR3220 is a polypropylene (PP) reducing tee with dimensions 32×20×32 mm designed for plumbing and irrigation systems. The fitting connects two 32 mm main lines to a 20 mm branch, enabling reliable flow diversion or system branching. Manufactured from PP, the reducing tee is suitable for potable water distribution, heating circuits and general fluid conveyance where polypropylene fittings are compatible.

Advantages

The polypropylene construction provides chemical resistance, low weight and corrosion-free performance, which helps extend service life in non-aggressive environments. The reducing tee offers precise dimensional compatibility for 32 mm and 20 mm pipe connections, ensuring a secure fit and straightforward assembly. Its smooth internal surface reduces flow resistance and sediment accumulation compared with rougher materials.

Suitable for

• Domestic and commercial potable water supply
• Irrigation systems and garden water distribution
• Heating circuits and secondary loop connections
• General fluid distribution where polypropylene fittings are acceptable

Key specifications

• Material: polypropylene (PP)
• Configuration: reducing tee
• Pipe connection sizes: 32 mm × 20 mm × 32 mm
• Surface: smooth internal bore to reduce flow resistance
• Typical applications: water and heating fluid distribution

How to use

Prepare pipe ends by cutting square and removing burrs; ensure compatible 32 mm and 20 mm PP pipes are clean and free of debris prior to assembly. Depending on the joining method for polypropylene in your system (mechanical, solvent welding, or fusion welding), follow the corresponding installation practice and manufacturer guidance. Align pipes with the fitting, insert to full depth and complete the chosen jointing procedure until a secure, leak-free connection is obtained. After installation, pressurize the system and inspect joints for leaks according to local codes.

Usage recommendations

Use the reducing tee with pipes and system components rated for the same operating temperature and pressure. Avoid exposure to aggressive chemicals or UV without appropriate protection. For hot-water or heating applications, verify compatibility of PP with system temperatures and follow local regulations for potable water and heating installations.
