Stuff to seal an air leak

[renichms]

Does anyone know what kind of liquid or gel could be used to seal an air leak? It's leaking where air comes from an air tank in the car and splits into 2 hoses. It must allow for some play in the hose, as putting the seats back in the car will surely move the hoses some, and it needs to stay sealed up tight, especially after the seats go in.

Is it leaking thru the hose or at the threaded junctions? If it's the junctions, try teflon tape, aka plumber's tape. Works just as well on air as it does on liquid.

The threads are not leaking and the hose itself isn't leaking. If the hose pulls to any direction at all, it seems to get enough of a gap between it and the plastic-brass-rubber fitting to leak air out. As air starts to leak, it all comes there and increases the pressure, resulting in the entire fitting blowing out like a rocket and the hose coming out...causing me to have to start all over again.

Sounds like you're not using the right "type" of hoses . I wouldn't know what to tell you to use but it should be able to seal better than what you have now.

you started with a kit like this, or something similar, right?

That means you used the supplied airline and connections, right?

If anything broke between now and then, you bought exactly the same type of airline and connections, right?

instead of bending the lines, you may have to make a 45 or 90 degree hard jointed connection instead....

OH thats Sweet love air bags what are they worth and how do they work on a PT .Where can you order them.

I would start with sealing the threads with teflon tape and then make sure that the connections are very snug. A loose connection is also a source for leaks.

The hoses aren't exactly bent...they curve but not bend at sharp angles. A loose connection is the source but it locks tight into place and stays that way for a little while. If a seat touches the hose or if anything bumps it around, it starts leaking. I'm looking to seal around the edges to prevent the leak. Some of these parts are new, all part of kits. I suspected a broken fitting so checked it when the hose blew out once. The rubber, brass and plastic pieces were wholly intact. I'm not running higher than usual pressure, either. It's quite baffling. So my solution is to seal any gap up, secure the seal in place, and test it like crazy. Other than no way to fix the leak today, today was fantastic. I replaced the wiring and installed the compressor kill switch and that all went slowly but flawlessly.

you CANNOT reuse air fittings! the small copper ferrels around the line bend to lightly cut into the hose for an airtight fit...

once you break a sealed connection, it's best to square cut the line and use another ferrel... always leave more than enough line for any flexing that may ocour and also leave enough to make a new connection if necessary...

having a loop in the line will give you this leeway, just don't make the loop too tight... if you look on the back of your refridgerator you will see the copper tubing in a coiled loop, that is why it's there....

they are called compression fittings, and the reason they are called that is that they compress the airline, whether it's plastic or copper tubing...

and it sounds like you still need to make a hard connection at these bends...

go to a heavy truck service center (Freightliner, Peterbilt, Mack, Kenworth) or maybe a truckstop garage for the ferrels and connections you need... these trucks use the parts you need for their air/fuel connections (air brakes, transmission, injectors, air dryers)...

is this like the componets you are using?
