Automotive Service Valve Leak

I'm a little confused about the access fittings you have.

Are they proper R134a clip-on fittings or car tyre valve type schraders?

Thanks for the note Brian,
these are the standard (99 Holden) R134a clip-on fittings with integral schrader valves.

After you take out leaking schrader valves, you should clean carefully the seat of where the silicon seal is pressed against the valve body.
