I need to clarify – got confused with so many other things I was doing.

The High Pressure hose as it attaches to the Receiver/Dryer does have an O-ring – I double
checked. But, the connection to the Expansion Valve on the Evaporator under the dash
did not have an O-ring. Further looking at the old hose end that attaches to the
Expansion Valve, the mating surface is concave sorta like it was designed to mate
to a convex surface. All this is new to me but I find AC interesting.

I’m vacuuming the system now and hope it holds.

Anyone have any comments about this?

Thanks

Carl
