Air Bag

[gerald37]

I have a 2015 RT does not have the air compressor. My air bag does lose a little air. It seems to hold around 30 to 36 pounds but I put 60 pounds in it it looses about 5 pounds over night. Has anyone ever used any type of sealant in the air bag or is this normal?

Yes, someone earlier posted that they pulled their airbag and greenslimed it. I'm assuming they then gently added a little pressure and rolled the unmounted bag around all axis to allow the sealant to fill any leaks. It's in one of the many threads most in the RT sub forums.

Search for Doc Humphries threads. You will find info there.

Thanks for the information. I will do some checking. I thought maybe a tire sealant would work but I did not know if it would go the the leak.

Some folks have done the squirt bottle of water with a drop of dawn or two, then spray the fittings to check for leaks.
Though to fill the leak if it is the bag with sealant, you'll likely have to unmount the bag and swish it around.

It is possible that you may have a tiny hole in air bag, but i bet you it is the 90 degree fitting on top of your air bag. Goodyear makes the air bag and it has thick wall construction. Also check your valve stem, (shrader valve). Good luck. Bruce

It was that 90 degree fitting on mine.

I had a slow leak in my (no compressor) air bag. I added about 2oz (or slightly less) of AmerSeal (sold by Lamonster) tire sealant.
It appears to be holding pressure.

I have some of that sealant and thought about trying it. I am going to check the 90 degree fitting first.

For what it's worth Gerald, I've done this 'add slime to stop air bag leaks' thing on my RT, a couple of other Spyders, and on a whole lot of larger 'air bag suspension' vehicles with minor air bag leaks; and for all of the 'little leaks' (ie, those that aren't visible as obvious rips or tears in the bag) I have found that if you add the slime when there's no air in the bag & then add close to max air pressure quickly, the slime will be forced into the leak/hole by air pressure.... even if the leak is up the top & covered by the piston!! But I reckon you'll hafta use shop air or equivalent at bead re-seating pressure with no valve in the stem to get it to work like that; normal, slow, tire inflating pressure doesn't get enough air in there quick enough to force the slime out the leak/hole, even with the tiny air bag....

And I haven't had any issues with the bends or valves in the Spyders inflation/deflation system either - just take the valve out of the Schraeder fitting under the seat, add 20-40 or so mls of slime (it's a small air bag) via the fitting, connect the air hose & give it a momentary 100 psi blast (it IS a small, a VERY small air bag remember!!) & then refit the valve, pressurise the bag to 80-90 psi & preferably leave it sitting at that pressure for a couple of hours if possible - obviously not practical if you are on the road/heading somewhere, but ryding on with the air bag at normal pressure seems to work OK too...

Go on, give it a try, what have you got to lose??
