PP-R Reducing Tee – a compromise-free connection

The PP-R polypropylene reducing tee is a key element in plumbing and heating installations. It is used to connect pipes of different diameters, allowing for efficient and tight transitions between sections with different parameters. The fitting is designed for welding, which ensures a durable and safe connection, resistant to high pressure and temperature.

This specific model, with dimensions of 90/75/90 mm, allows for reducing the diameter from 90 mm to 75 mm and back to 90 mm. This is an ideal solution in situations where it is necessary to adapt an existing installation to new devices or modify its layout.

Properties and application

PP-R reducing tees are characterized by high chemical and mechanical resistance. PP-R material is corrosion resistant, guaranteeing long-term operation even in difficult conditions. Welding PP-R elements creates a connection that is impermeable to liquids and gases, minimizing the risk of leaks and failures.

• Versatility: Suitable for cold and hot water installations and central heating.
• Durability: Polypropylene PP-R ensures longevity and resistance to mechanical damage.
• Tightness: Welding guarantees a hermetic connection, eliminating the risk of leaks.
• Chemical resistance: The material is resistant to the action of most chemicals present in water and heating installations.
• Easy installation: Welding is a relatively simple process that can be performed using appropriate tools.

Design and operating parameters

The reducing tee is made of high-quality PP-R type 3 polypropylene, which ensures its strength and reliability. This material is characterized by a low linear expansion coefficient (0.15 mm/mK), which minimizes stresses in the installation caused by temperature changes. The fitting is designed to operate at a maximum temperature of 95°C and a nominal pressure of PN10 for cold water and PN16 for hot water and central heating (depending on the pipe wall thickness). It is important to select the correct operating parameters of the pipes and fittings to ensure safe and efficient operation of the installation for a long time.
