If you have any 'sketchy' or suspicious leaks of R-134A from Failing Schrader Valves hidden inside of your HI (RED) and LOW (BLUE) HVAC Manifold Gauge Set Service Ports... THIS an inexpensive Ball Valved Tool Set that you can use to quickly and easily replace those Leaky A/C Charge and Gauge Port "Bicycle Tire" Valves... and NOT have to Evacuate the System of R-134A, Pull a Vacuum and then have to Weigh In a New Freon Charge.

This Pair of Combination Tools is available for just under $22.00 with Free S&H. I also recommend using a light coating of NYLOG around the Silicone Seals of the New Schraders (requires a separate purchase) just prior to using this Kit:

Now if you could find one to change the rubber ball style valve in the high port of the full size vehicles I might be a buyer if it's cheaper than the $45 acdelco line... Mine leaked after an evac/recharge.

However that's a cool tool that I didn't know they made for vehicle ac. I knew they were available for commercial ac and such but not 134a. Could also just use pag oil for the seal on the Schrader if you have that laying around vs nylog which I've only seen used on thread-on commercial fittings. If you're worried about it. Most send shraders in dry without issue.
