I want a high flow kit for AC season.

[OldSchoolMech]

So I got a YJ 7 CFM Bullet after the death of my Red Robinair pump. I wanna start to change up my vaccum style.

My pump can't be locked off so I was gonna use my pump then one of these




Then buy two appion high flow kits (core tool and hose) and a Bluvac micron gauge.

Would this be the best bang for my buck or what would you suggest??

[gravity]

yes. i have the bluvac with all the functions. i just bought a bluvac lte which is all that is needed.

get rid off the tree and go to supply house and get a tee fitting for the pump.

i have a 3/8" tee on my pump which i hook both hoses to.

Your core tools will have vacuum rated valves on them.

Like gravity said, fit a Tee into the pump and go for it.

I didn't bother going to supply house, I just stopped at the hardware store and fitted one up with some brass fittings.

It worked well until that pump gave up.

Why is the yellow jacket tee a bad idea??


I know cost wise but I can lock pump off to see a rise.

Put your vacuum gauge on the side tap on the core tool. And if you want it even better put another core tool off the side tap and mount the vacuum gauge on that so you can isolate your gauge when you release refrigerant into system.

The fitting is a nice fitting for the vacuum pump, but it isolates the vacuum at the wrong location. Valving off at the core tools isolates the hoses from the system. All hoses leak. With the Bluvac that will be very apparent.

Does anyone have pictures of thier setup?

[jim bergmann]

Here is the kit that we sell a lot of. You can just get the pieces that you need. The video shows how it is hooked up and used.



Here is a link to our vacuum training page.

I like the YJ tree because the access port between the 2 ball valves makes for a convenient place to hook a hose up for breaking the vacuum with nitrogen when doing a triple evacuation, without having to shut the pump off, or switch any hoses.

Don't wanna start a new thread.

What are the size of the Appion core tools where you hook the hose up to?
Are both ends of the hose the same? Or can you get custom hoses?

I am trying to figure out all the sizes etc.

Appion makes their core tools in 1/4" and 5/16". I have the 1/4" and it is 1/4" inlet and 1/4" outlet.

You can get HD hoses in just about any combination of fitting end sizes that you want.

My set up has 3/8 hoses. 3/8 on the tree side and 1/4 in fittings at the core tool side.
