    I have tried using Teflon tape and it only lasts a day or so when I use my Omega Super Charger. Does anybody have any experience using some kind of pipe dope for a sealant … if so, what kind will hold up to that kind of pressure. My problem appears to be on the air output valve on top of the SC. When I use Teflon tape the pressure rises VERY well, but it only lasts a short time and I have to take the old off and put new tape on … needs something more permanent or longer lasting

    Does your output connector have a dowty seal. A dowty seal looks like a metal washer with a rubber inner edge. You don’t use teflon tape on BSPP connectors which is what I think is on the Super Charger!

    Thurmond … it’s an L shaped ball and socket type fitting on top

    If your not sure what style of fitting you have, check out this thread.

    Call AOA and ask because you should not be having an issue and they are the experts. I don’t have one here to look at and the parts diagram is not clear enough to tell. If it is a metal to metal seal then they have to be very tight.

    The fitting is on top of the compressor and it looks like a wide male fitting with a plastic o-ring in the hole on top. A steel ball with a hole in it fastens down to the plastic o-ring by a threaded encasement which screws down over the male fitting. I know it sounds weird but they changed out the fittings on the air output last year … it used to be just a male fitting and a female quick release on top attached to the hose.

    I’ve talked with Todd at AoA  a dozen times already and he says that he is at his wits end on the leaks this unit has. Only had it about 2 1/2 weeks and only been able to top off my 75 cu ft tank 3 times. I may very well be sending this back for something that works.

    Thanks Tominco … it appears to be a BSPP as I don’t see any taper to the threads.

    Is this what you’re referring to?

    Permatex makes some really good thread sealants.  Able to withstand about 10k psi.  I have used a ton. Although you should not need it for bspp fittings.  Some of permatex stuff works so well that once you put it on, you won’t get it off unless you use a torch.  Get the right fittings instead.  Been there, done that, won’t do it again.

    Tominco, I am new to AGN and haven’t put in the necessary time to learn all the ins and outs of the forum as far a getting pics and whatever to come up for me … all I am getting is a black box with an X in it. Presently all my time has been consumed with trying to get air in my tank for the last week or so … trying this, trying that, talking with Todd, talking with AoA and it’s just about consumed all my free time.

    ​Rey, I fully understand what you are saying about permatex and loc tite and I agree with you about getting the right fittings but these ARE the fittings that came with the Super Charger. If they would not work correctly they shouldn’t have been shipped with the compressor. I have tried simply tightening them down as well as I could to no avail, it will not hold pressure … it will with Teflon tape but the pressure is so great that the tape doesn’t last long and will start leaking after a day or so. They make a sealant named Masters Pro Dope that can be used on air compressors and hold up to 10,000 psi, it never dries hard, lubricates the metal and comes off as easy as it went on (according to advertisements). In the best possible world, I should not be having problems like this and I know it .. this unit is advertised as basically a plug and play compressor … you plug it in, you set the pressure you want, adjust the bleed valve for time, put in the antifreeze, make sure the water pump is working and fire up the compressor and it does the rest. But it wont hold pressure unless the entire system is closed off and leak proof. The problem is that at 4500 psi a leak so small as to be almost undetectable will keep you from getting that high. Heck, I’ve even immersed the whole tank in the bath tub trying to see some bubbles and the only ones I’ve seen is a very small leak coming from the burst disk in the tank which I tightened up about 1/6th of a turn to seal it off. I’m at my wits end, Todd is at his wits end and sometimes I hear voices in my head and that’s the only reason why I am to the point of trying to think outside the box and just try to find something that works … I really don’t want to have to pay the freight sending this back to Arizona. Thanks for listening to my rant … I’ll get something worked out one way or the other … I always do … if I don’t destroy it first.

    be careful working with pumps motors and controllers ….i do it all day and teflon can void warranties  when used with the wrong pumps .im not saying this is your case ,,i would send it back..if the experts cant figure it out ,,change it out,,good luck

    Mine leaked at that same location until I tightened it. I know you’ve already done that, but perhaps u could take it apart at that L-shaped fitting, make sure everything is aligned, and tighten it again. It took more torque than I thought and I was just as certain a you that it was tight enough, until I tightened it just a bit more.

    USE “J B WELD” AND YOUR LEAKS WILL STOP.
