Low pressure side shares space with heater core lines. That's why so
much tighter.

High pressure barbs must be made of steel. Brass just won't cut it.
Maxes out 125-150 psi. Steel barbs are rated in thousands of psi, but
I still find that hard to believe. Hundreds maybe, but thousands?

Personally have found "porous hose" reasoning to be untrue. My Two
Tone Lincoln is running with a low side hose from a '72 Galaxy no
problem. Old O rings are probably more to blame.

Schrader valves get old and leak too.

Ultimately boils down to cost of freon vs making system factory tight
again. For example: on the Lincoln I just bought, compression nut is
rusted to condensor input tube. Tried to hold with some vise grips
(not tight enough to collapse line), but it still wanted to turn with
nut. Wasn't worth potential damage to condensor to replace that O
ring, so I left alone. System may well leak there, but at $3.50 a can
(NAPA case quantity) I don't lose any sleep.
