Brass half coupling with flat seal GW ultraPRESS - 16 G3/4" 1009105002

Brass half coupling for press fittings – reliability and tightness of installation

This brass half coupling with a flat seal, designed for the ultraPRESS system, is a key element of every professional and domestic water installation. Made of high-quality brass (CW617N), it ensures durability and corrosion resistance, guaranteeing long-term, trouble-free operation. The connection diameter of 3/4 inch (20) makes it ideal for standard installations.

Design and application

The half coupling is used to connect multilayer and homogeneous pipes using the press fitting method. Its design with an internal metric thread and a clamping sleeve enables easy and quick installation. The simple shape facilitates integration with various installation elements. It is worth remembering that appropriate crimping jaws are required for installation – “U” or “TH” profile depending on the pipe diameter (for a diameter of 26 mm, “C” or “TH” profile).

LBP function and benefits for the installer and user

A key feature of this half coupling is the controlled leak function LBP (Leak Before Press). This means that in the event of incorrect crimping of the connection, a visible leak will occur during installation testing, allowing for quick identification and repair of the error. This not only saves time and costs associated with repairs after installation is started, but above all guarantees safety for the end user. Additionally, the diameter identification ring facilitates the installer's work during assembly. The EPDM O-ring seal provides additional tightness of the connection.
