Description of π§ FJC 2632 Service Port Adapter: The Ultimate Solution for Efficient Servicing
Manufactured from T6 Aircraft Aluminum. Same strength as steel. R134a service port adapters will adapt existing R12 service ports to R134a service ports. Will accept standard R134a Quick Couplers used with R134a manifold gauge sets. Use when retrofitting from R12 to R134a.
Great for conversations where you can't get the charging hose around a corner. Before installation, the wire on the low-pressure side R12 must be removed.
Perfect fit for my 1992 Mazda Miata. However, the Schrader valve core must first be removed from port R12. I had a tool in my cycling gear for this purpose. Also, the device rotates, but if you screw it to the R12 connector, you can adjust the angle and tighten it to keep it from rotating.
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.
