01 xj A/C service port valves

I found out today that my Hi pressure valve is leaking.

Does anyone know if you can buy them separately and how to identify the size of the valve(s)? The Hi and Lo are definately different. The Lo appears to be much bigger!

I found the tools to remove/replace them without evacuating the system.

Thanks for any help. I need my A/C!!!!!!!!!!!!!!!!!!!!!!!!

There is a schrader valve inside that's likely bad. It's similar to a tire stem with different seals.

You should be able to find them just about anywhere as well as the tool the change them.

Once done, you should take it to an AC shop to evacuate the system, then recharge to specs. If fact, if you're sure the valve is bad, just have them do it.
