Review on 🔧 FJC 2632 Service Port Adapter: The Ultimate Solution for Efficient Servicing by Sammie Prince

Appears to be made of quality materials. Before installation, you must remove the original Schrader valve. There is a gasket on the inside of the adapter where you screw it into the R12/22 fitting. Make sure it's tight. Once installed, the Schrader valve on the R134a port adapter ensures a tight seal. It is recommended to use some red Loctite to make sure it will hold and do a pressure test before fitting the R134a.
