I'm carrying it in my cubby in case I ever encounter an R12 car that needs use of my R134 pressure gauge -- I'll screw it on long enough to use the gauge, then remove it.

Damn, I just got back from NAPA and Autozone. I went to NAPA first and they said they'd have to special order it (no stores in town carry it)! The guy suggested Autozone or O'reilly. Then I went to Autozone and saw the cheapo aluminum for like $13. I didn't buy it, I want the steel ones where else can I go? I don't have a Pep boys but I do have O'reilly, I'll try that I guess.Originally Posted by Rich_NYS

I just when to O'Reilly auto store, they had a few options for fittings but they all looked like they were aluminum. Where else can I go to find the steel fittings?

These are the NAPA fittings you want:

If my small town NAPA has them, they should be available nationwide.

The aluminum valve fitting will not break. You always have to be careful when connecting the gauge fitting to the valve because the line the valve is attached to is aluminum and weak, you are more likely to crack the line than the fitting. You always take out the original schraeder valve when topping it off with a conversion fitting otherwise it might bend the fitting underneath it and you won't be able to fill the system. Make sure you put in a can of green dye so you will be able to see a small leak should it occur.

Negative on cheap aluminum ones. Hold one up to the light -- you can see right through it. They don't seal anything by themselves. What looks like a schrader valve is just a pin that flexes in a bent piece of metal. There is open space on either side of the metal piece.

My VIN: Banged your VIN'S mom
I picked up a nice working r12 machine for 100 bucks and another 100 bought me 18 cans of R12 replacement and a few cans of oil charge. I bought this over a year ago and haven't used it yet, but it's nice knowing I have it in case, especially with R-12 service being all but extinct these days.

I went to NAPA and bought both 409901 and 409903 and brought them home. When I tried to thread them onto the high and low side ports I couldn't use them both. I found that the ports on my system are both 1/4", the blue topped one (409903) worked with both ports. 409901 is apparently 3/16" and was too small for my high side port. I went online and I tried manually searching for 409902 which happens to be the 1/4" version of 409901!
So I pull the schrader valves and just thread these onto the ports with some teflon tape? Is that the acceptable method for permanent installation of these fittings?
Thanks,
-Greg
