Loc-Line double coupling 1/2" to 1/2", black

Loc-Line double coupling 1/2" to 1/2", black, small connection, big effect

Sometimes a flex arm is just missing a single part so that everything sits exactly the way you have it in mind. That’s where the Loc-Line double coupling 1/2" to 1/2" comes into play: an unobtrusive black coupling that virtually turns ball and socket upside down in no time and opens up new possibilities for building your system.

Deliberately reverse the direction of ball and socket

With this Loc-Line double coupling you can deliberately reverse the direction of ball and socket instead of letting yourself be limited by the standard configuration. Where previously ball met socket, you can rotate the connection with the double coupling so that it fits your setup exactly. We think it sounds like a small part, but in practice it’s often the crucial trick that finally makes the flex arm work the way you need it to.

Use a socket at both ends of the flex arm

By using this double coupling, you achieve that a socket is available at both ends of the flex arm. This means you can flexibly attach accessories, nozzles, or additional Loc-Line elements on both sides without having to cobble together awkward intermediate pieces. The result is a well thought-out, cleanly built system that can be quickly adapted if you later want to modify or expand something.

Robust black design for 1/2" systems

The double coupling is designed for the 1/2" Loc-Line system and fits precisely into existing flex arms. The black design appears unobtrusive, almost elegant, and visually blends into many setups, whether in the technical sump, on machines, on cooling lines, or in other applications where you use Loc-Line. We’d say: functionally focused at its core, but pleasantly understated in appearance.

Flexible areas of application, from aquariums to workshops

Whether you want to guide flow and return in a saltwater aquarium a bit more cleverly, direct coolant precisely in the workshop, or simply need more freedom of alignment in a small DIY construction, the Loc-Line double coupling 1/2" to 1/2" makes it easier to configure the flex arm exactly the way you want it. No magic involved, but very practical.

Easy handling in the Loc-Line system

As you know from the Loc-Line system, this double coupling can also be installed without tools. Snap in, align, done. We know how it is: you don’t want to fiddle around for hours, you just want to quickly create a stable, tight, and reliable connection. That’s exactly what this coupling is made for; it integrates seamlessly into existing 1/2" flex arms and adds the option of swapping ball and socket as needed and using sockets at both ends.
