OK, forget everything I said about testing the hoses. BTW, that set appears to be made by TIFF and they are one of the better sets.

are you using a set of gauges for R134a by any chance? I was under the impression you were using a set of standard gauges.

you do not need adapters. Maybe I did not explain it well enough. Take your low side hose off the manifold.
