What's the highest psi output for a York? I've got a couple of cylinders (4"x12") that are rated to 3000psi

Mine pumps to 100lbs easy

I have my pressure switch shut mine off at 125lbs. It would keep going. Never tried to max it out. I hear they will pump 300-400psi.

300 PSI! <IMG SRC="smilies/skull.gif" border="0">

Mine switch is set at 150lbs. and that is plenty to pop beads on, run air tools and air up real fast.

Ok, I have one also...Can you adjust the pop off valve to POP at a different psi.? Mine pops at about 121psi, I've been afraid to jack with it...That sucker will scare the snot out of you when you tweaking on it!!

pop off valves(at least every one I've seen) are non-adjustable.Look around they do come with different pressures.Personally a 120psi pop-off is perfect.

I have mine set to shut off at 135psi, but just look at the charging pressures of an AC system, or the AC gauge set... Some very hi pressuer capability.

300 PSI!

No, 3000 psi. Used to check accuracy of underground mine methane detectors.

The cylinders are 4"x12". They have the pressure regulators attached. I'm afraid the cylinder walls are so thick though that they won't do much good. I have to figure it out.

I need to find out the top end of the York psi because that would be the weak part of the system.

Hey, I could plumb a string of them with relief valves so that when I get hung, I could pop the valve and hop over the rock!

i have seen them hit 400 in a ac system but that is with a cool gas coming into them i think they would get two hot with air at 300# plus. mike

Run 'em in series, outlet of one into the inlet of the other, five or six of 'em setup like that ought to get you close to 3000 psi...

Between 300-400 psi max. It'll be screaming hot on the outlet side. Your cylinders can handle the max output easily.

I apologize for my newbie response, but the point I was trying to make is that no single stage air compressor that I know of gets any where close to 3000 psi. My york loads down enough to slip the lose belt at around 150, where my pop-off also blows. Rather than fill your tanks with an OBA setup, take them to a gas supplier, and have them charged with CO2 or something closer to there design pressure, this would make better use of them than filling them to 100 psi or so, or get OBA, and a resonable (and lighter) tank. It'll work with the tanks you got, but it's like a f/r 60's behind a 4-cyl driven 31's, kinda overkill

The nice thing about the high pressure rated tanks is that the walls are 3/16 to 1/4 steel. It really comes in handy when you mount them under your frame just in case you hit a rock. I picked up a old scuba tank at the flea market for $25 and like it a whole lot better than my sun performance 125lb tank. Not only is the scuba tank heavy duty but it's covered in rubber, no rust...

raider,

Call me stupid, but I'm pretty sure that when Ranger replied with 300 psi, he meant that the York puts out 300 psi (that was your question right?).

Raider,

There are also different cfm ratings on the various different Yorks too. Up to 10.? cfm. Three different cfm ratings, that I have seen, so far.

1988yj - that's why I got interested in them. Those things have to be able to take a hell of a whack.

New 300-400. they claim 100-200 worn out..www.onboardair.com has the specs. it doesnt give you psi but the info in order to figure it out

It gets used alot! The pressure switch stuck on a few weeks ago, and caused the pump to keep running, when the pop off valve blew, I though I would raise the hood to find a piston through the block, but no, just the 225psi safety pop off letting go. So a very used York will put out at least 225psi. For what thats worth, there it is.
