I don't know bars/mbars/inches. Can anyone tell me how many psi this pump can achieve? Does it have a vac release valve or a vac gauge?

I have to answer your question with a question What are you going to use it for? I use it to ensure auto A/C systems will hold a vacuum for at least ten minutes
808881
Bar/mars/inches or terms related to the amount of vacuum a pump will pull. This is not a compressor so will make zero psi. It does not come with a gauge or valves. It has one vacuum hookup port only. It is a good unit and pulls a good vacuum. I use mine for stabilizing wood. A two stage unit will achieve a quicker job.

It does not come with a vac release or a vac gauge. I bought the guage separately. It uses a different measurement than PSI.

There is a gauge, but the adapter cant lock on to the tube when pumping. Air keeps leaking, I could be bad luck. But I couldnt pump anything with it.

the package did not indicate max PSI but I am doubtful if it can achieve that as the pumping action is only about 4 inch draw. My advice is get a bigger pump with higher pressure.

Hi, just measured it and its just under 6 1/4 inches. It's a great pump, too bad it's too big :( It's the 1/5 91025 pump. The base is round but there is a protrusion on the side where the hose connects that makes it too wide for a 6" pipe. Hope that helps!

Bars of pressure? Never heard of this! Seems to be a question for manufacturer. Sorry.

Hi, the outlet and inlet of the pump have a 1/4" (6mm) bore. Regards, Mark.

So sorry for the delay. Measuring from the surface where the pump sits to the point where the threads begin for the discharge pipe is indeed less than 4". Hopefully you will have room!

My shop vac is a Channel Lock 4 HP with a hose connection of 1.625 inch diameter. Works perfect without tape.

Line in 1/2 inch out and drain are 3/8. Helps to have good pump runs best at 75 psi. Blessings Blessings

I measured the O.D. of the largest part of the barb with my caliper and it showed .305". The largest part of the fitting up against the nut, is .313". Mine came with a piece of tubing about 7" long to connect to the a 6 valve outlet port (included). The barbs on the oulet ports measured .205". I've had this air pump for 2 years now running non-stop with zero defects. If all the ports are used the pump is fairly quiet for its size and it really moves some air. When used with airstones the water looks like it boiling. It tends to run a little hot but this hasn't seemed to affect the pumps performance. This pump is little animal. I think it would air up a truck tire. I'd buy it again in a second. Hope this helps. I measured the O.D. of the largest part of the barb with my caliper and it showed .305".

I dont have any specs on the unit right now but it did come with. Instructions that info may also be on it o didn't. Go thru it. But the pump works great for my need.

I don't have any specs, but I can tell you the pump works for my application. I use it to augment the engine vacuum on my 1997 Volvo S90. When accelerating or climbing a long grade, the vacuum drops and the HVAC, which is vacuum controlled, fails into default. The reason for this is a small leak that is not easily repaired. I know where the leak is but to fix it requires dismantling the whole HVAC unit. SO I installed this small pump through a check valve and controlled by a rocker switch. If I notice the HVAC is malfunctioning, I flip the pump on with the switch. The pump is very small but it pulls a strong vacuum with a small displacement. CFM would not be appropriate measure. Cubic inches per minute might be better. I would doubt if it is continuous duty device. As I said it works for this application. I would guess that it draws perhaps one amp.

The pump has an inch and a half or inch and a quarter outlet. You will need to reduce down to 3/4 and add a male threaded nipple designed for hose attachment. Home Depot or Lowe's can show you exactly what you need.

Sorry, not sure about psi. The gauge on my piece of crap schrader pump broke on one of the first uses. I just know that it filled it up. But for me, the co2 would leak out, even in new tubes, front and rear, within a couple of days. So I'm now hunting for a floor schrader pump, and will just keep this for emergencies.

7 in to bottom of bar. The bar can intersect the h20 valve and/or the supply hose. I had to install the bar in one bath after placing the unit behind a installed toilet and snaking hose in front of bar. The second bath install required only two bolts and turning the bar 180 instead of the supplied four because the water assembly was exactly on the valve with no room for the bar. The units are great, 5 stars and worth the hassle to get the bar installed(not to mention required to stabilize the unit)

The vac comes with plastic tubing. There are three tubes of difference diameters. Each tube is approximately three feet long. Other than the tubing Q&A, read the reviews. The product has a poor float mechanism and the unit failed for many users in 2-3 years. Air leaks are a significant issue with the tubing design.

I don't have a gauge to know how low but I am pretty sure you can get it below 5 psi. Works close to a need valve.
