TSWCBYYLB AC Manifold Gauge Set for R134a R12 R502 Refrigerant 3 Way Car with 5FT Hoses Couplers & Adapter Puncturing & Self Sealing Can Tap Freon Charge Kit

I’m thoroughly impressed with the quality of this set, especially at this price point. As a retired technician with 40+ years of experience, I’ve used a wide range of manifold sets, from budget options to top-of-the-line equipment. This set is perfect for DIY enthusiasts. It includes everything you need to properly charge a R134a system or even an older R12 system (just be sure to get a clamp-on can tap). I strongly recommend using a full set like this instead of quick charge kits that only monitor the low side—you need to see both sides to avoid major issues. This set offers great value and functionality for anyone servicing their own system. Highly recommended!
