Hey guys, i just installed my air ride system and i still have some leaks i'm trying to sort out. I first used the teflon paste, and i had leaks where the fittings go into the tanks. So i took it all apart, and used telfon tape instead. I managed to stop half the leaks but i still have some.

What am i doing wrong? I already warped one bushing from over tightening,so i replaced that(no leaks from that one now) is it possible i warped the other fittings as well?

Most importantly, is there something that i could just apply to the outside of the fittings so i don't have to take everything apart again and re-teflon? Would sylicone work? or jb weld?


Any help would be greatly appreciated

take apart the leaky fittings and inspect them ,if the threads are not sharp they will still leak replace with new fittings and use loctite # 545 sealant for air systems and hydraulics ,this stuff has never failed me . only one thing about this sealant is you have to wrench the fitting in place quickly befor the sealant starts to set/dry you should be able to find it at a good hardware store, if you cant find it anywhere, its availble at grainger. theres a grainger in every state practcally their part no. 5A237 $32.15 for 50 milileter bottle or look in the internet under grainger.com

I have allways had a problem sealing up steel tanks, I manufacture Aluminum ones now. To fix your problem it is usually the tanks problem not the fitting. If you fit a few systems its best to purchase and run a tap through the tank threads to clean them up before you go ahead and screw in your fittings. When they make the steel tanks they have poor quallity control and there is a lot of paint in the threads to clean out. Most imprtantly do NOT over tighten the fitting or it will leak, just thread tape it, screw it in firmly but not over tight and check for leaks, if it leaks dont just try and tighten it as this will not stop the leak, pull it out, re-thread tape and try again. Same goes for liquid thread tape.
The air fittings I make come with the grey sealant coating on it, this reacts with the lock tight 569 to swell and fill for a leak proof assembly.

Boss your tanks are NPT? if they are you dont want want some guy running a thread all the way through because pipe thread is tapered and thats how it seals. Just curious because my bags leak through the fitting because i dont think the guy stopped with the tap and ran the thickest part all the way through. no fittings naturally stop they all just bottom out.n any suggestions

[SLAMMED63CHEVY]

What I did was used Teflon tape and a thin layer of clear silicon over the Teflon tape and then put the fitting in and that worked of me I don’t have any leeks

[boss air]

Sorry I stand corrected, dont run the tap right through, only 1/2 way through!.

[hotrods316]

wasn't trying to correct you, just wanted to make sure. because man i swear my bags are tapped too deep. thats all, since you said that i know that my fittings should stop but they aren't. thanks boss

it sounds like your tank is screwed, with all the low grade and priced tanks comming in from China and Hoosier (the ones who make Firestone tanks) this seems to be an ongoing problem. Is the air fittings actually bottoming out and screwing right up to the flange on the ports? or are they taking up on the thread? we will need more detail. You may have a dud tank, where did you get it from and does it have a brand on it?

[boss air]

I didnt read the post properly, my bad, what brand are your bags should have been the question, not what brand of tank.
I have witnessed bags being taped on a machine by sight free hand so I can easily beleive the bag has been taped too deep however I have seen viariations in air fittings too so see if another brand air fitting fits up better.

bought the bags from AIM. Do they make their own or just resell firestones?

Can I use silicone to seal the threads?

I bought parker fittings which have about 2X more threads but they also bottom out, they run all the way down until there is no more threads just unthreaded material. The other fittings have less thread and run the hex part into the bag.

I dont know what to do except for silicone or something. I am using the good teflon paste too. So please help me out.
