I got one.

Found out that my Robinair vaccum blank-off was leaking.

Also found out that my TIF micron gauge sensor assembly was leaking.

The Blue-Vac is MUCH faster in resolving the micron numbers than the TIF.

I found out that my Thermal vacuum pump gets down to 36 microns.

It will take some time to figure out how to set this one up. I do not yet have a way to blank off the system accurately.

I do like the small size.

Since when do blank off valves NOT leak?

Every pump I've ever had leaks like a sieve at the blank off valve. I'd waiting to see this gauge stack up against some of the better micron gauges.

how are u guys attaching to the bluvac? a hose, 1/4" swivel? tonight i brazed 2 pressure taps onto a piece of 3/8 copper. capped off one end and hooked the other end to my shraider tool. off the shraider tool i hooked up the bluvac and a 3/8x1/4 hose and vacuumed down. i got it to 60microns and blanked off the shraider tool. it slowly rised to 450 before i left. im wondering if my fittings are leaking that i hooked up to the bluvac. right now im using a 1/4" flare swivel that goes to a tee that has a shraider depressor in it. will see how many microns its at tomm morning

The problem with performing a blank-off test using a vacuum pumps blank-off valve is that you still have residual moisture inside your hoses (and hopefully they are not permeating in a vacuum!), as well as exposure to a small amount of the vacuum pump oil (which likely has moisture). Additionally, every connection, gasket, etc. will contribute to the vacuum rise.

Either connect your gauge to a port on the system as far from the vacuum pump as possible, or use a vacuum-rated valve core removal tool with a side access port so that your blank off is testing only the system (and your core tool and micron gauge).

Chris if enough guys wanted one would you please make a core remover with a 1/4" female connection in stead of the male connection for these type of gauges that have a male flare fitting.

It would probably be more cost-effective to get a female-to-female connector, and some vacuum gauges even come with those as part of the package.

Thats one more connection I don't want to be looking after.
FWIW it seems all the micron gauges worth a dang have a 1/4 male connection and IMO is better since it will need hardly any maintenance and will keep your gauge in service with options.

Chris FYI I would buy it.

Hello,

i m new here on this forum.I come from Slovenia and i read all the good things about BluVac.I m very interested into buying it, but i dont know where to get it in Europe?
Can somebody please help me with this issue.I already contact TruTech Tools, but still no answer.

Thank you and nice day,
