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:
