Function fittings LINE-ON-LINE is a unique range of products designed to be installed in pneumatic systems. They are distinguished by their efficiency, small dimensions and compact design. The modularity of their construction allows parallel, serial or combined parallel-serial connection. They are available with FOX push-in fittings at both ends (for pipe-pipe connection), or with a male thread connection at one end and FOX push-in fitting at the other (for thread-pipe connection). The threaded connections made of nickel-plated brass combined with the body made of plastic give a very lightweight connector.

With LINE ON LINE function fittings, any pneumatic function can be realized at any point of the system. Permanent marking of the body with a function symbol and flow direction facilitates identification and assembly.
