Ok so I keep hearing about this appion core removal tool, hos is it different from the yellow jacket CRT???

appion is vacuum rated to 20 microns, yellow jacket isnt vacuum rated

...and it's a much nicer piece, aesthetically and mechanically.

Wow. All these pages to answer the question about should one use a micron gauge. From 2006, yet.

"Yes."

Not rated or they just never bothered to rated it?

i used my yellow jacket core removers before i got the appion, never had a problem pulling a deep vacuum with them, but the appions are much nicer to use and i know they are rated for the job.

The way I understand it is Appion actualy tests each piece befor it goes out including the hoses and manifolds

The YJ's are for vacuum use.

I've had the YJ's, C&D's, and now I have the Appion CR tools. The Appion ones are the best hands down. They are built better, and the ball valve lever "snaps" into place when closed off so if you bump it it does not move.

The biggest difference as I know it:
Appion is the only one on the market that put double o-rings on the shaft. It does what all double o-rings do when pulling a vacuum -- seals.

Appions are the only ones I use in the shop now.

I have never seen any other appion tools other that their recovery machines, and vacuum pumps.. Sure would like to see the CRT though, if it's better then I need some, good tools makes our jobs easier at times!!!

I have a C&D CRT and thought I'd try removing the valve core on my last evac. So I recoverd the refrigerant ok with the cores in and broke the vacuum from the recovery machine with a little nitrogen. Then put on the C&D but I couldn't get the valve core out, so I took the C&D off, took the core removal stem out of the CRT and put it right on the valve core, it would turn out about two turns and then wouldn't turn anymore. It was stuck. Turned it back in, then out again, it would quit turning. Didn't want to break anything so I tighten it back up and left it in. It had a cap on it, system was 12yrs old, but the service port looked clean inside.

No success on my first try. Has anyone had problems getting a valve core out like that?

Sometimes people find a way to smash the flare in. So your core won't come out...

I just had one, too.... It looked like it had got hit.

I wonder if overtightening a flare nut wouldn't do it as well....
