The breathing hoses have
different diameters on the two
connectors. The side with the
larger diameter goes to the
mouthpiece and is fastened
with the hose.
The connecting pieces of the loop have different diameters to avoid mix-
ups. The difference is difficult to tell with the naked eye. It is helpful to
push the socket briefly into the head. The exhalation side has the larger
diameter, so it does not fit on the inhalation side. The O-ring on the exhale
side is also thicker than the one on the inhale side. When the side is
determined, the nozzle is pushed into the union nut and fastened with the
hose clamp.
