Review on 🔌 R410a Charging Vacuum Port Adapter Brass Converter: 5/16 Inch SAE Female to 1/4 Inch SAE Male Flare (4 Packs) by Brody Jacobs

I have 3 mini splits from Panasonic. I bought these R410A adapters to upgrade my R134A gauge kit. After installing the adapter on the end of the charging line hose, I tried to connect it to the port on my mini split outdoor unit. The protrusion in this valve was not long enough to push the pin in the Schrader valve. I'm only giving them 2 stars because they seem to be well made except the gasket feels a bit stiff which can cause leakage at the joint. A good gasket should be rubber, not plastic.
