Review on 🔌 Aupoko R1234yf Quick Couplers: High/Low Side Manual Connector Adapters for A/C Refrigerants Manifold Gauge Set by Damon Murray

fits my 2019 Honda Accord. Designed in Taiwan, made in China. Easy to put on and take off. The only confusing thing about the adapter is the "open" and "closed" labels on the check valve. The valve must be turned fully "open" to allow the adapter to connect to the service ports. And "close” the valve almost halfway, so the pressure gauge on the manifold shows pressure.
