What's the max pressure you can get to with this sealer? I just bought this unit and mine maxes out at only 26 on the gauge.

A short explanation may help. A vacuum is negative pressure. The vacuum gauge reads in inches of mercury equal to how many inches in a tube the pump could pick up a column of mercury. Twenty eight (28)to 29 inches is a perfect vacuum. That much vacuum is usually only obtainable with a two stage pump or higher such as one used to evacuate a/c systems. At 26 that is a substantial vacuum and as someone else stated with moisture that is not likely to be higher as the water boils because of the vacuum. Water will boil as low as 30/40 degrees Fahrenheit in a fair vacuum. Twenty six maybe 27 is likely the most a small single stage pump can do, but is still substantial as all but a tiny amount of air is removed. Don't sweat it these things are very good at their job. Hope this helps.

You can get a little further that 26 .... but not much and only with dry goods. The problem is at low pressure the water starts to boil, and the conversion of liquid to gas stabilizes the pressure in the chamber.

I asked a very similar question, except that mine barely got to 23. I believe the answer is your elevation. I am at approx 4400 ft. elevation, I am guessing that you are at approximately 1000 ft. elevation. At that elevation, the atmospheric pressure is approx 28.86 inches mercury. The VP112 is capable of about 90% vacuum. So 90% of 28.86 is just about the 26 that you are seeing.

I asked this question of a Ary technician Gary on Sept 23, 2014. Gary told me the VP112 should get up to about 27 inches of mercury and if it doesn't it's probably due to internal manufacturing mistakes by Ary that cause leakage at the canister port even when the canister port is not used. My VP112 pulled only 5 inHg when it arrived. My own temporary repair got it up to 25 inHg. A perfect vacuum at sea level is 29.92 inches of mercury. Ary's warranty policy (even for dead-on-arrival products) requires the customer to bear the expense of shipping back for repairs.

My compressor is a 5hp 80 gallon putting out 155psi and this regulator has handled that with no problems.I could not find out the max input before I bought mine either, and had to put the pressure to it and see what happened.It has been almost a year since I started using mine and I have regulated as low as 9lbs for powder coat.The gauge goes to 160.It's a pretty big well built unit that will take you by surprise when you take it out of the box.

Take a good look at the updated description. They changed the regulator size to 10 psi! My guess is that their manufacturer in china screwed up by putting the 10 psi in the box instead of the better 20 psi. So they just changed the description. Be careful and read the description. High pressure? I think not.

70-75 psi seems to work well. more pressure does not appear to have any greater effect. Hands down, one of the best purchases I have made in some time. I only use 110 volts. It has been more than adequate for my needs.

I used a Kobalt 10 gallon compressor with a tank pressure of 155 lbs and set the line pressure from 85 to 92 lbs. and it worked just great. Compressor was not overworked, and nails were driven through various dimensions of lumber.

Although it is not in the description, when I got mine it had a sticker on the regulator that stated 150 PSI maximum Inlet pressure. So be careful if you have a 2-stage compressor that pumps up to 175 PSI.

I don't know the max pressure but anything under 100 psi should be OK. The readout will read up to 999 gallons.

I didn't have any problem with the gauge. Having never used this product and not being a car guy I was using the gauge, but once the compressor kicked on the needled redlined. So I had to start letting coolant out, while the compressor was engaged, until the needle on the dial dropped back to the proper zone. Some of those responses may have been from people like me who have no experience and just don't know how to work it properly. That being said, I am sure you could buy just a gauge on amazon or your local car supply store.

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.

That's a tough one. Seems I have to actually start using slight force at about 30 PSI. My tires need 50, so from 30 to 50 it gets a bit tiring. Still not hard, just a lot of pumping. Also seems the faster I pump the better it works. Slow and steady doesn't seem to move the gauge.

I don't have a max but my well is always over 80 PSI and under constant pressure. I am sure this thing can handle anything the schedule 40 PVC pipe can handle. It is built like a tank. Very high quality.

It depends on how long the line is and the size of the line. Don't you have higher than 15 psi?

I returned mine. Could only get 130 PSI out of it. Connector did not leak though.

The max pressure says it's 150 PSI... But when I tested it got around 140 PSI! But when it's close to the 150 PSI according to the pressure gauge then it gets restarted.If you do offroading, it's a really good compressor and you can permanently install it in your truck. It can withstand water, mud... you name it... if it get's damage get another one!

The max PSI rating on the hose is 2600It's a great hose at first glance I thought it wouldn't last but I have used the hose a dozen times or more with no trouble

The pressure gauge used to both read the pressure, and set the maximum pressure, has a max setting of 150psi. The trip needle would probably make it cut out at 148ish. So in theory it should be capable of this pressure.FYI the compressor is fairly slow. I used it on a tire with 20 psi, it took about 3 minutes to fill it to 35 psi.

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.
