Review on 🚘 Upgrade Your Car AC System: Orion Motor Tech AC Gauge Set with Self-Sealing & Puncturing R134A Can Tap, Ideal for R134a R12 R22 R502 Refrigerants. Includes 5FT Hoses Adapter Adjustable Couplers, Freon Charge Kit for Effortless Maintenance by Paul Hubbard

My fingers almost fell off after trying to plug in my AC system for 20 minutes. This one immediately presses the pin and freon goes everywhere. All over my engine and cables and myself. Always shut off the engine before using that big fat pointer. After the first try, more freon came out of my system than went in. abominable! 2 stars because after putting this thing in my valve it finally seated properly so something came out. To update! The company replaced the item and I got a much better one! If you have any problems with yours, contact them and they will help you.
