does it bleed off with out un hooking air pressure

Yes, there is a small bleed off button on the side that you press. No need to un hook from the valve to do it.

Yes--you can bleed off pressure without unhooking it. What I am unsure about is how high the supply pressure can be without damaging the unit. i.e. can the air compressor be at 90 PSI while you are trying to fill a tire to 32 PSI

Yes...you don't want to bleed off pressure unless unless you are replacing seals or valve parts...BUT, you don't want to leave it cocked.

Have not experienced that issue. Some issues with air bleeding by at the valve but otherwise works well

Yes, but only one time. As soon as the WATER pressure gets high enough to explode this AIR pressure gauge, its over, along with your hands and or fingers.

Yes it has quick disconnects on the suction and discharge valves. Very minimal water spilled during maintenance.

Yes it pops off. It will occasionally seep air, just push on it and it will pop in place and usually quit.

Yes. When you shut the water off some of it will come back and splash out of this attachment (and get your hand wet). This is a good thing. Just dry your hand and be glad that the pressure has been relieved from your hose and other more expensive attachments you have at the spigot (e.g., timers).

The tiny hole in the flange with the air bleed valve should be mounted top dead center when positioned on the water pump--or at least on an OME thermostat for a Toyota Tacoma--maybe some 'stats don't have an air bleed hole?

Yes it does. A red light comes onto indicate that you are applying too much pressure.

It does shut off when you stop spraying. Disregard the other comment that indicates that it stays on. It pretty much maintains a fairly consistent PSI that you can set. When you stop spraying, and start, there is a mildly larger burst of PSI than the usual steady flow. Nothing that I would consider a problem though. This thing is worth every penny. I highly recommend it!

No, but if you angle the gauge after getting the reading it will bleed the air.

You're right. It will drip IF the gauge is turned other than almost upright. Mine stays at a slight angle to make it easier to read and I haven't lost any fluid from it. Also, I really like the gauge. Not sure what the result would be if you didn't make the cut.

I do not know that it is physically possible not to bleed a small amount of air, but certainly nowhere near all the air. Try putting in a little extra air to compensate for any bleed off.

Well I have been using this type of gun foe about 9 months and I have not had to bleed the air. I drop 2 drops of air tool oil after inserting a fresh grease cartridge, connect the air hose and pull the trigger till grease starts to flow, then continue to keep greasing. Hope that helps.

No. It's meant for cooling it has a dye that you can look for leaks , but leaks can come from anywhere allot of ac units just need a recharge , if you know you have a leak than you'll need to run a pressure test , but if you never really service your ac unit chances are you just need a recharge

Yes. If you look at the top side you will see the brass nut that your 1/4 line goes to. When your compressor shuts off the head pressure will come out of that valve

Yes it does. Once it reaches the set pressure it turns off. Turns back on when pressure drops.
