my a/c's low side connection port is leaking, it's the little thing inside (#9000 on the picture)



if i try to wiggle that valve, it stops leaking until i let go, is there a tool that i can buy to turn it? i know for a tire u can screw that piece (#9000 in the picture) out with a tool, what about for a/c?

 

a tire valve tool might work give it a try
otherwise at a local parts store they sale the tool its like 8 bucks made just for ac systems.
