PP reducing tee 90/50/90 302-90/50/90-V

PP-R Reducing Tee – a compromise-free connection

The reducing tee made of polypropylene PP-R is a key element in plumbing and heating installations. It is used to connect pipes of different diameters, allowing for effective branching of the installation. The fitting is designed for welding, which ensures a durable and tight connection, minimizing the risk of leaks.

This specific model, with dimensions of 90/50/90 mm, allows connecting a 90 mm diameter pipe to a 50 mm diameter pipe, and then returning to a 90 mm diameter pipe. This is an ideal solution in situations where it is necessary to adjust the pipe diameter to changing hydraulic needs.

Properties and application

PP-R reducing tees are characterized by high resistance to corrosion, high temperatures and pressure. The PP-R material is also impact resistant, which increases the durability and safety of the installation. Therefore, these fittings are widely used in:

• Plumbing installations in residential and industrial buildings.
• Central heating systems (CH).
• Underfloor heating installations.
• Industrial installations transporting liquids.
• Systems for distributing utility and technological water.

It is worth remembering that the linear expansion coefficient of PP-R is 0.15 mm/mK – important information when designing longer sections of the installation, to take into account potential dimensional changes caused by temperature.

Advantages and benefits for professionals and users

• Durability and tightness: Welding provides a connection impermeable to liquids and gases under pressure.
• Chemical resistance: Polypropylene PP-R is inert to most chemicals present in water and heating systems.
• Easy installation: PP-R welding is relatively simple and quick, which translates into time savings during installation. However, it requires appropriate equipment and qualifications.
• Low price: Compared to other installation materials, PP-R offers a good price-quality ratio.
• Versatility: Possibility of connecting with various PP-R installation elements (pipes, elbows, valves, etc.).
• Safety: The material does not contain harmful substances and is safe for health and the environment.
