A/C Schrader Valve Tool

Yes, I've looked at the HVAC forum with the search engine, found some information, but nothing definitive.

I need to replace an R-134a Schrader valve, or maybe just tighten it a bit.

Can a valve stem tool for a tire stem be used? For both sides? Only one side? Neither?

Along the same line of questioning, where do I buy replacement valves in quantities of one?

If a special valve tool is needed, where do I add that to my bag-o-tricks?

I'm asking here, rather than over at the HVAC forum, because I'm more likely to get an answer instead of an opinion.

Thanks,

Pop

I am reaching wayyyy into the memory here but I think the tire valve stem tools work. Its worth a shot....I recall them working for R12 valves. If its leaking I'd probably get the right valve, referigerant is not cheap nowadays, and it has the compressor oil in the mix too.

It will work for one side, not sure about both. I'd have to look at my truck for sure.

Pop, make sure it's a Schraeder type valve. My 98 chevy truck had what I 'thought' was a Schrader but it actually had a ball in there that did the sealing. The replacement was about 10 bucks for the good brass one.

The Schrader tool and the valve stems can be had at O'Reily's. It is twice or so larger than the tire tool IIRC. Don't have it with me to compare.

I agree to do it right or you'll end up chasing your tail....

...sorry, couldn't resist.
