Connection method
Inside the device, most gas connections have been implemented via FAST connectors
(FAST – Fast, Safe, Tight). These connectors provide a tight transition between the
hoses and connections with different diameters. The soft sleeves prevent the risk of
glass breakage in comparison to rigid screw connections. There are different connector
versions.

So-called Fingertight screw connections are also used. These flangeless fittings consist
of a conical nipple and a banjo bolt. These hose connections seal purely by tightening
the plastic banjo bolt finger-tight.
