i have a set of R12 compatible a/c gauges. they have the screw in type connectors. the R134 connectors are the compression fitting type. is there a way to convert mine so i can use them on R134a or do i have to get a new set of gauges?

awesome. that first kit looks like it only has two adapters in it, but gauges have three fittings? what am i missing? those look as if they connect to my gauge set so i can use them on newer cars, seems like exactly what i want. thanks!

The third fitting is for the charging hose (yellow), the tank/can adapter is for that one.

thanks, i went ahead and purchased the set.
