i dont see why not i am going to a tee with 2- 3/8 flare tee that will go directly into my pump. at the moment i have a 1/2 to 3/8 reducer on my new JB 7cfm

My vacuum pump has 1 1/4 and 1 3/8 port is there any reason I couldn't use this instead of the $65 dollar tee yellow jacket has

2 Valve core removal tools, 2 half inch hoses one on each side of system, and directly teed to vacuum pump and with a micron instrument. Nothing too spectacular just good old fashioned evacuatin'

Looks like a nice set. I'm still thinking, still trying to evolve into an e-vac set-up that doesn't cause me tantrums, fits of cursing and hours of frustration looking for non existent leaks. I want a vacuum pump that'll suck the nuts off a squirrel at fifty yards and I can judge whether the job is done when the copper starts to collapse! Evac drives me nuts!

Ha!

I use this one. Yellow jacket 60971

So I could have saved $10 and bought one. So if blue is universal I like the RED one better so I can use this on all oil types?

No offense was intended...just curios if you had information that differed from what I have read concerning cross contamination.

The Blue Label Nylog can be used universally or specifically with an HFC bound synthetic oil system.

Blue Label is completely miscible in POE or PAG lubricants and exhibits good

stability in both mineral and alkyl benzene oils

Links to and quotes from the manufacturer's information on Nylog.

Relax, dude.

This.

I went to the website and it explains a lot. Says use blue stuff for everything if you want. Like gravity said, lot less tacky. Doesn't seem to clog up as much. Also says to use it under and over teflon on pipe threads. Has anyone used it for this purpose? As a pipe thread compound that is.

I'll have to agree with gravity. The above quote is just ridiculous!
Miniscule amount for what?
Are you putting the bottle in the system?
Is leak lock compatable?
