air bag fitting

I am looking ahead to air bag replacement when the weather gets hot, and I am getting stuff together.

I have in my hand an angle fitting, a 1/4 inch tube compression to 1/4 inch NPT, which I thought I read was the fitting to use between the air bag and supply line.  I quickly saw that the tube measurement probably should be 3/8 inch - my actual measurement of the tube was .39 inch.

The 1/4 inch NPT on the fitting I have is actually right at 1/2 inch, width measured with a ruler.  Is that correct for a 1/4 inch NPT?

Please verify that I will need a DOT approved 3/8 inch tube to 1/4 inch NPT angle.  Where did you get yours?

Matt, search dsd and he will loan you the tools we modified to do the entire job. He takes a deposit to get them back. No need to struggle or break anything. it is much faster and easier tor remove tires. Included is a tool for the fittings. After the first one each will take you less than an hour at a snails pace.

Bags tools. I am more than willing to loan out my tools with a full replacement deposit. This is the actual replacement cost of the tools unmodified. Shipping has been about 15 each way. They are currently in my possession.

Could someone please verify that the fitting is a 1/2-inch NPT male to 3/8-inch plastic tube angle?

I ordered HF269NTA-06-04, and the adapters I received were labeled that, but they are not correct.  I will call and get it straightened out, but I need to know what I am asking for.

I called Hose and Fittings.  I explained the application, and they verified the part number to be correct.  They just sent the wrong fittings.  Correct ones on the way.

Thanks!

Replacing airbags on my '99 U320. Bought bags from Kelly's Truck Parts south of Nacogdoches, They carry Automann bags and even knew what part number I needed. $170 each. Online sources were out of stock.
Removed fender skirt. Well worth it. Positioned my four 12" spacers. Initially very concerned about not having acquired the special tool kit that the community passes around. The front bag by the entry stepbox is very tight quarters and at first I was thinking it to be near impossible as there is barely enough room for one hand. Once I realized what others had done - cutting off the stud below the airline fitting was the best action, I cut off a spare 5/8" open end wrench and loosened the airline fitting and used the Sawzall to cut the big stud just above the nut. With the fitting out of the way I was able to get an air ratchet in there on the 1-1/8" nut. Couldn't have done it without the air ratchet, as there is not enough room for my regular ratchet to click. It also made nut removal/install faster. Heated the fitting with a handheld Mapp Gas bottle torch to loosen it for removal from the stud. Glad I had some teflon paste like was used at the factory on the threads of the fitting. Upon reinstall, I used the short wrench to tighten the fitting.
This job was not as difficult as I feared. The rest will be a piece of cake!
