Brass screw-in-fittings with one seal

This connection system of dezincification-resistant brass is designed for the fast connection and disconnection of coolant tubes in closed coolant systems in industrial applications, welding technology and robot applications.

The robust and dirt-resistant screw-in-fittings of Series 2600 combine ease of use, since no tools are required, with an economical design and long life. Series 2600 features full flow and an enclosed O-ring, and requires only minimal installation space. The lightweight and compact fittings are available in a wide variety of compatible versions and can be adapted to every individual application.

The practical release sleeve protects the fitting against penetration by impurities and is designed for convenient operation also in dirty conditions. The inserted tube is held securely and without damage in the housing by an inner collet.


They offer maximum reliability under extreme conditions for closed coolant circuits in industrial, welding and robotic applications.
