They may have something at an auto parts store, they sell the cans there, they probably have the hose you need.

all 134 A and r-12 gauges in domestic refrigeration is 1/4 in flare we use 30 lb bottle not the little cans I was just mentioning the r-12 blend freon I bought was in a can and it had the proper fittin also automotive refrigeration fittings are different than domestic refrigeration. You can get the fitting at nappa to convert automotive to1/4 in flare I know this because I was in a jam 200 miles away from my shop and ran out of 134A I bought a 30lb jug of automotive 134A and had to find the adapter to the jug so I could hook my gages to the bottle

Or Napa :)

The hose I have WILL screw on to a can of 134a, it won't peirce it. Also, the amount threads on the can are too short, so the hose will screw on, but it won't bottom out so that the inside of the hose touches the top of threads. It won't seal.

The threads on the top of the can and the threads on the charge ports are the same, except for the threads on the can are too short for the hose to seal properly.

Yes, "So you need the hose that fits on the can and pierces it, and also the other end needs to attach to the charge port correct? "

So they must have this at a refrigerant supply store?

Thanks

Back to charging...

The neither the high or low pressure changes when the compressor is running. Are they supposed to?

Thanks
