Female thread adapter GW 20x3/4" WT Wavin PPR 4047818

Polypropylene and threaded connection – reliability in your system

This Wavin PPR half coupling combines the advantages of polypropylene welding with the convenience of a threaded connection. It is an ideal solution for connecting PP-R pipes with installation elements with an external thread, such as valves or fittings. Made of high-quality polypropylene (PP-R) and brass, it guarantees durability and corrosion resistance, which translates into a long service life of the installation.

Construction and application – flexibility in every detail

The half coupling is designed for creating connections in domestic water installations – both cold and hot – as well as central heating. Thanks to a diameter of 20 mm (DN 20) and a 3/4 inch thread, it fits standard installation elements. The welded polypropylene connection ensures tightness, and the nickel-plated thread finish protects against corrosion. The eccentric construction facilitates assembly in tight spaces.

• Versatility: ideal for connecting PP-R pipes with threaded fittings.
• Durability: made of high-quality materials resistant to corrosion and high temperatures (up to 75°C).
• Tightness: welding technology ensures a reliable connection without the risk of leaks.
• Compatibility: compatible with the Wavin PPR system and other PP-R systems.
• Dimensions: nominal connection diameter 1 is DN 20, and nominal connection diameter 2 is 3/4 inch.
• Safety: PP-R material is harmless to health and the environment.

The half coupling is characterized by a maximum working pressure of 20 bar, which makes it suitable for most standard domestic and industrial installations. The length of the element is 59 mm, and the wall thickness of the connections is 4.5 mm, which ensures mechanical strength. The use of gaskets further increases the connection reliability. The Zeta value of 4.3 indicates low pressure losses of the flowing medium.
