Reducing coupling K5 C/Z water PN10 25/20 3079761

Pipe diameter reduction in water installations – reliability and ease of installation

Reducing coupling K5 c/w water PN10 25/20 is a key element of the Wavin Tigris system, designed to connect pipes of different diameters in hot and cold water installations. Made of high-quality polyphenylene sulfone (PPSU), it ensures durability and corrosion resistance, which translates to a long service life of the entire installation. Thanks to precise workmanship and the use of radial pressing technology, it guarantees tight and reliable connections.

Construction and application

This coupling allows reducing the diameter from 25 mm to 20 mm, which is useful in situations where it is necessary to adapt elements of different dimensions. Its simple construction facilitates assembly, and the presence of seals made of ethylene-propylene-diene monomer (EPDM) rubber further increases the tightness. The coupling has a support collar that ensures connection stability during pressing. Designed to operate at a maximum pressure of 10 bar and a temperature from 0 to 70°C, it will work in both domestic and commercial installations.

Advantages for professionals and end users

• Fast installation: Pressing technology minimizes the time required to make a connection, which is especially important for larger installations.
• Tightness: Seals and precise dimensional fit guarantee a completely tight connection, eliminating the risk of leaks.
• Durability: PPSU material and solid construction provide resistance to mechanical damage and corrosion, extending the life of the installation.
• Safety: DVGW quality mark for water confirms compliance with safety and hygiene standards. The KIWA certificate further proves the high quality of the product.
• Acoustic Leak Alert: Innovative acoustic leak detection function makes it easier to identify potential problems in the installation – a faulty fitting will emit a loud whistle under pressure.
• Compatibility: The coupling is compatible with the Wavin Tigris system and other systems with similar technical parameters.
• High strength: Made of materials resistant to tensile forces, ensuring connection stability even under changing operating conditions.

Thanks to these features, the K5 reducing coupling is an ideal solution for both professional installers looking for reliable and easy-to-install elements, and for end users who value durability and safety of the water installation in their home.
