NOTE: The starter kit come with only the three valve selections 1/4, 3/8,1/2 if you have the Sman gauges and a vacuum pump that uses a 3/8 fitting you will need to purchase an additional 3/8 fitting, (1) A10790 KF-16 to 3/8 FFL Adapter.
Interesting mine came with a 3/8 fitting a half inch fitting and a quarter inch fitting for vacuum pumps. And I’ve bought three or four of these kits I’ve also bought the full blue case with the three hoses the entire kit with the 1 m hoses .
@@coldfinger459sub0 yes sir the other end hooks up to the sman gauges which is 3/8 I also have an old robin air vacuum pump with a 3/8 fitting. So I needed to by an extra 3/8 adapter.
@@GL0697 oh yes, totally forgot about needing two 3/8 in that scenario. I forgot because all my vacuum pumps also have the larger half-inch or three-quarter inch fittings . Or the larger commercial flared flat T25 fittings
Is there a reason to have a second core removal tool for the micron gauge instead of a simple vacuum-rated ball valve? Excuse my ignorance; I'm new to the whole vacuum - micron gauge setup.
If you can find a threaded ball valve then you can use it They’re usually pulling vacuum from one side with the one hose method You do not disconnect the micron gauge on the other side you ball valve it off. You still need an opening, which will at least have to be removal tool.
Yes. But you have to purchase 134 or YF couplings that have quarter inch threads directly on the back of them then you could put the core removal tools directly onto them. True Tech Tools I have released videos about this over the Facebook group ( automotive HVAC technicians ) Vacuum videos about Jim Bergman using the equipment and showing you exactly how to hook it up. I too have made videos in the past on exactly how to use the adapter fittings and core removal tools for doing evacuation and recharge. These hoses are only refrigerator. Refrigerant inside only serve one purpose. And vacuum only in these hoses
Have you tried charging liquid refrigerant on the side port of the valve core tool? Tried two times using 2 different core remover tools. They both leak. The metal fittings freeze then shrink including the ball valve. The leak just stop few minutes after unfreezing. Is it not possible to charge on the side port?
@@coldfinger459sub0 It's a 410a inverter with only 1 port. So much time wasted pulling 30 microns using the tiny side port so I can have the valve core with the push rod installed at the bottom. I don't understand why the hell does it keep stopping at a certain micron if left for so long at the vacuum pump. it seems like it's forgetting that it's still under vacuum. Isolating the pump makes no response on micron reading. When opening the ball valve there is a few seconds of delay before micron reading change then jumps to 10k+ microns then drops to 1k. I tried 5 different units and 2 different brands and they do the same thing. All of them are inverters with indoor units higher than the outdoor. I tried if a molecular sieve could stop this from happening but it failed. Moisture is bursting aggressively with molecular sieve but it makes micron reading more harder to understand if there is a leak or just moisture.
Go BIG ....or go home ......good stuff ! Jay.

@@coldfinger459sub0 no conductence issues there with those fittings.

Thank you for this! I was looking to upgrade my vacuum setup. Do the vacuum core tools connect straight to the quick-connect couplers?
Yes. But you have to purchase 134 or YF couplings that have quarter inch threads directly on the back of them then you could put the core removal tools directly onto them.

Yes if you get the cupping with 1/4” threads

No problem
