Vacuum setup

[thecarpenter]

Thanks to all you guys that took the time to post your setups! Mine is just like JTCHVAC, except I need to put a blank off valve on the pump. I do however wonder about the tightness of all the CRT's and blank off valve. I know I had a cheaper CRT once that I originally bought to change bad cores on pressurerised systems that I know would not hold a 500 micron vacuum. let alone 300 which I really like to pull to. May try AIRESEARCH idea without CRT, but where do you put micron gauge (I guess a tee in line but another leak point?)

I'll be switching mine up a bit. Will post when I get more chances to do so

The carpenter , You could install the micron gauge near the equipment with a brass tee and a short hose or coupler.

If you keep up with the gaskets in your hoses and snug everything down , the setup is capable of holding less than 200 microns.

That is without any type of sealant.

Appion CRT is rated at 20 microns. This also gives you a port for your micron gauge.

We get a lot of questions on the how to and what do I need to perform a proper evacuation. I put together this piece to better explain the process and the tools required.

I get about 5 sec. of that link before it goes to the Categories. I'm using an iPhone. What's up with that?

I just watch some Yellow Jacket videos and they use their crt when using their vacuum setup

I haven't actually seen the appoin in person. I'd like to know what construction is different than YJ. I have no problem pulling well below 500, heck just last Thursday I pulled down to 180 or so.

It is detecting your i phone browser and going to a I phone friendly version of our site. You can shut that off at the bottom of the page, or navigate there through the categories. It is under vacuum, vacuum training.

The only difference that I know of is that it has double "O" rings. Seems to make a better seal. I have my YJ & also 2 Appion CRT's I feel more confident with the Appion than I do the YJ.

Sometime just doing what makes you feel is the best job is what it takes.

I have not tried to pull a vacuum with my YJ in a few years. They may work, they may not. But Appion is actually rated for 20 microns. I have yet to see where YJ will state what their CRT is rated for (in microns).

So- OK it just gives me that warm fuzzy feeling to use the Appion.

Hope that answers your question.

Just not sure what double o-rings means. Where do they seat on the flared fittings?

Those appion crt's are the cats pajamas
