Do these couplers have a shut off on the top of them?

Yes, the red or blue part twists to open or close the valve.

Do they make car-side hi/low pressure fitting with threads? So you can easily attach these to the gauge set when not in use?

Anthony, If I understand what you want to do, you want to attach your couplers to your a/c lines and leave them there, and when not in use you want to attach those to the "storage" fittings on the backside of your gauge set. I did some quick research and I believe they do make what you want and Amazon carries them. What you need is a set of R12 to R134a adapters. They should have a female SAE 1/4" flare R12 side (to attach to the "storage" fittings on the back of the gauges) and male quick connect R134a side to attach to your couplers, obviously you will need two, one for the low side and one for the high side. It looks like they are sold both separately and in sets. Just search Amazon for "R12 to R134a adapter" and you should find what you need. It's a good thing there's still a bunch of us old timers out there with old cars and old R12 systems that need to be converted to R134a systems. Just remember the gauge fittings are SAE 1/4", male flare, and I think the quick connect fittings are standardized although I 'll have to research their designated sizes/names. These may also be available at your local auto parts store. Hope this helps........
