R12 R22 R502 Screw to R134A Fast Conversion Adapter Valve

These worked very well

Good quality, will do the job.

I used these for my 1978 Dodge air condition system. They fit on existing fittings without removing Schrader valves. Only problem there are no caps with this product and existing caps do not adapt to this product. Have no way to prevent dirt from getting into the end of fitting.

Bueno

leaks worse then the old one I was replacing spend 3 more dollars and get something better

I needed these for an ac compressor pressure test plate, I used once and they worked so I can't comment on longevity for frequent use

The adapter only fit the low pressure port and not high pressure port. I was not too happy with this order. I was not able to get the reading of the high pressure port. Have to return it.

I just used these to have a quick connect mounting point on my gauges. Threads fit the existing mounting points and the stems fit the quick connect fittings

Used it to fill low pressure side of a/c unit. High pressure side one is useless, might come in handy. Overall I'm happy with the purchase.

Bardzo dobra jakość wykonania.

Very good thanks
