## Summary description

PP-R pipe tee SiGMA-Li T75 is a 75 mm polypropylene (PP-R) plumbing fitting designed to join three pipe runs in heating, potable water and general plumbing systems. The tee provides a reliable, corrosion-resistant junction for distributing fluid flow, suitable for welding (socket fusion) installation and use in residential and light commercial piping applications.

## Long description

PP-R pipe tee SiGMA-Li T75 – 75 mm polypropylene plumbing tee is a three-way fitting for joining three pipeline runs in heating, potable water and general plumbing systems. Manufactured from PP-R (polypropylene random copolymer), the tee is intended for socket fusion (welding) installation and provides a corrosion-resistant junction that maintains hydraulic continuity and long-term dimensional stability in residential and light commercial installations.
Advantages
The polypropylene construction ensures chemical and corrosion resistance, low thermal conductivity and long service life under standard operating conditions. The socket fusion end connections create leak-resistant joints when installed correctly, and the uniform material reduces galvanic and electrochemical interactions. The 75 mm diameter is suitable for main distribution lines and larger branch connections, offering dependable flow distribution with minimal pressure loss when matched with compatible PP-R piping.
Suitable for
 Hot and cold potable water distribution systems
 Heating systems including underfloor and radiator circuits
 General plumbing and drainage in residential and light commercial buildings
Key specifications
 Material: polypropylene random copolymer (PP-R)
 Nominal diameter: 75 mm
 Connection type: socket fusion (welding) ends for heat fusion joining
 Application temperature range: suitable for typical domestic hot and cold water and heating temperatures (follow system design limits)
 Corrosion resistance: high, non-metallic construction
 Typical use: potable water and heating distribution
How to use
Prepare the connected pipes by cutting square and deburring the ends to ensure full contact in the socket. Clean the socket and pipe ends according to the socket fusion tool manufacturer's instructions. Heat the pipe and fitting ends with a suitable PP-R welding tool to the recommended temperature and join them concentrically, keeping alignment until the joint cools to form a homogenous fusion. Allow sufficient cooling time before applying pressure or flow to the system. Installations should follow local plumbing codes and the recommendations of the heating or water system designer.
Usage recommendations
Use compatible PP-R pipe and components, and follow socket fusion equipment guidelines and safety procedures. Pressure and temperature ratings depend on the overall piping system and must conform to applicable standards; verify design limits and perform pressure tests after installation.
