They can be reused, just make sure the hose is like new.
Does anyone have a source for these? Can anyone tell me if they are single use only or can they be re-used?
TIA.
Take what you can with you to the nearest big truck dealer: Freightliner, International, KW, Peterbilt, Volvo/Mack etc. and go to the parts department.
STACEBG: The bags on axle airide suspension take a larger hose- both on tractor and trailer. But the cab airbags use the smaller hose and smaller airbags depending on application. Steel cabs found on some Peterbilt, KW, Western Star( Freightliner product) over 18,000lb, may have larger bags/ airlines). Ive delivered all of them from the factory to dealerships ( piggybacked 4 at a time) and each job is different.
