Hi, Wilbur,

Snippage of all but the refrigeration bits...



No compression, then. It might mean a clog but it probably means a leak
with low or no pressure. Hope that that brass nut just vibrated loose and
after a tightening it will hold pressure.


Yah... I'm waiting for a response from the guys who helped me design it
as I was buying it from them. Not that it's in any way unstandard - just
that they're up to speed on my installation and situation, and I'd have to
start over with Veco, their supplier/US distributor for Frigoboat.

Further, it's a quick-connect; the o-ring does the sealing, not the
pressure of the nut against the other (technically, it's not a nut, but a
hex end on a male connector), so I don't want to mess with it until I get
something from the horse's mouth.



However, on the yellow line (I'd have to see if that's inbound or
outbound, cuz I don't remember), under the silver connector, the brass
nut and a very slight portion of the tube were wet. Thin enough not to
be oil, but thick enough to possibly be.

So, you may be right about the freon (oops - R134A) situation. I have a
set of gauges, but need to get the adapter which will allow me to put
the can on the schrader valve cap before I start messing around in it.


I got mine from NAPA - they had it in stock. But, to install it involved
removing the Schrader valve in the original so the new one could be
screwed on piggyback as it has it's own Schrader valve. An excellent time
to add the adapter is when the system is low on or out of refrigerant
because you will lose it anyway when you remove the original Schrader
valve. You will also need a schrader valve tool.


As it happens, among the thousands of parts and tools aboard, I have one
of those, leftover from my bicycle-working days. However, I THINK there's
a proper adapter to allow my can to attach to the gauge set, which IS
schrader-compatible. I'm a bit surprised, as it's a recent purchase, that
it didn't come with such an adapter but, (fading) memory has it that I had
to buy the hose set separately. I've not yet dug out the set; perhaps the
end (but my memory has it that it doesn't) of the supply already is set up
to screw a 134a can on, and puncture it.

However, what you're saying sounds like the suction side schrader would
have a nipple-type fitting, and you'd connect an automotive setup to it
for gas installation?
