4.6.5 Parts of the inlet valve (P50)
NB: The inlet valve has grooved parts to prevent the bottle assembly from turning during
use of the P50. Make sure that these parts fit together correctly when the bottle assembly
nut is tightened, or the inlet valve will not seal properly.
Make sure that all parts are coated thoroughly with silicone spray during assembly.
This extends the lifespan of the O-rings and helps the parts to slide together more easily.
TAKE CARE not to lose the steel ball-bearing. A spare ball-bearing is included with the set
of O-rings for the P50.
