Rather than buying a set of automotive gages, I have all of my refrigeration equipment I use to repair refrigerators. Can all of this be used to do auto ac? All I should need is fitting adapters, right? Where do I get them?
Yes you can use them. The pressures are within the range of standard r-12/22/502 gauges. You can get adapters and fittings from ebay pretty cheap. I just bought a set of automotive a/c gauges from HF though since they were on sale for about $30. Had to buy an adapter to attach them to my vacuum pump though. Also had to get a can tap for them to use the 1 lb cans.
I got it off of ebay. The red and blue hoses should fit the other manifold, at least on my auto gauges they are the same. But the yellow one is larger.
The can tap I got is like THIS ONE and the vacuum pump adapter I got is like THIS ONE. I got the adapter like that so I can just put it on the standard flare fitting without having to change the fitting all the time. "My" vacuum pump actually belongs to my employer so dont want to change the fitting if I dont have to.
I've got all the equipment for charging, vacuuming, and so on, I got the adapters to tap into the truck, but my manifold's male fittings are smaller than the hoses that hook to the truck, so i'll look into the reverse fitting as referenced by you, thank you!
I just didn't know what they were called to look them up.
That's funny, my boss is really picky about those adapters that he bought for our 134a cans, we use automotive refrigerant due to the fact that it's cheaper, and it has the 1/2" conenctor on it, I just never made that connection until now lol!
