Question:

What is the proper way to remove the air line and/or fitting from the air bag without damaging the fitting. Need to do so in order to add airbrake antifreeze.

Expert Reply:

First you will want to completely deflate the airbags. Then to remove the air line from a push to connect fitting like part # F3128-1 you first push the outer metal ring inward and then pull the air line out. You may also need to push in on the air line and then pull out all while holding the metal ring in. It may take a few tries but this is the correct method. Then in order to remove the fitting you will want to place an open end wrench on the hex nut directly above the threads (see photo). When you reinstall the fitting make sure to use some thread sealer like part # LT37482.
