Review on 🌡️ AURELIO TECH 4-Way A/C Manifold Gauge Set for R134A, R410A, and R22 Refrigerants | 5FT Hose, 3 Acme Tank Adapters, Adjustable Couplers, Can Tap by Michael Radhakrishnan

The first kit I got didn't just hold the vacuum in the manifold. In other words, with the hoses only connected to the manifold and vacuum, the vacuum only lasted 15 minutes. The hoses also came loose, so when testing or filling the system, the connections to the manifold began to leak. Tightening the connections stopped the leak for 15 minutes. I sent the set back for an exchange. Credit to the manufacturer that the replacement kit arrived within 2 days. The new manifold holds the vacuum. I will update the review and rating after hooking it up to the system to see if the hoses come loose.
