Push-to-connect fitting removal tool - GIF

There is an automotive version used on trucks, DOT approved and used almost exclusively on all big trucks for the past 30 years. If never disturbed and are not subjected to any movement of the line is secured so it cannot move they will normally last the life of the vehicle if I have to remove or replace an airline, the fitting gets tossed in the trash, because it will never reseal properly or if it does reseal it will soon begin to leak. Whenever possible I replace them with DOT approved brass fittings that use an insert and Ferrel. Most trucks have a transition manifold for passing the airlines through the firewall these as of late are mostly made of plastic with the fittings molded in place. It is a regular occurrence that an airline or a bunch of them need to be removed to work on the truck when this happens if the truck is over 10 years old or runs in extreme heat and cold you might as well inform the customer that unless the manifold is replaced and all of the airlines cut back 1/2" they are going to eventually have a bunch of leaks. The problem is you can't always shorten most airlines that much A new manifold will run between $400.00 and $1200.00 depending on the truck. The fittings are not much of a problem on a truck less than 3 years old because none of them are going to last until they are 10 years old
