taking about HVAC…. I saw a car AC repair kit the other day which comes with a can R134 freon and a special can to help “reseal” a leaky car AC system .
these 2 pressurize cans come with a cable/hose with a control valve and built in pressure meter
buy simply changing the AC car side connector end to standard 3/8 – 16 UNC any chance these C kit could become an easy to use LU test kit.
a) to check leaks with a bit… of r134 gas
b) to use the sealing agent can to actually swell up the LU seal joints if any leaks are detected
replacing the end connector to a standard 3/8 – 16 UNC. would make for an easy to use test & reseal kit .

r134 is apparently not to bad for the ozone layer and not much would be used anyway … compared to millions of leaky car AC
