Section 10 - Connecting the water bottle
The first step is to connect the two stainless steel pipe assemblies to the top of the bottle.
The two pipes will only fit one way around as shown below. The Swagelok female miniature quick
connects have a
‘collar’ which is pulled in order to insert the male stub fitting.
Once you have connected the two pipe assemblies to the top of the bottle you simple connect the other
end of each pipe assembly to the OHG using a 7/16” spanner.
