suville · 01-01-2010, 04:51 PM

Been readin for hours and hav'nt come across the info so which fittings are recommended for the fitting into the air bag 90* or 45* or?Thanks for your help guys! Want to take advantage of suicides 15% sale

Rollie396 · 01-01-2010, 09:12 PM

I'm not sure it matters.If I remember correctly I have 90's rear and 45's front.It's just what worked best for me.

**lolife99** · 01-01-2010, 09:13 PM

I ran swivel 90's on all 4 corners on my blazer.

tcb-1 · 01-01-2010, 09:38 PM

Keith, do you have a link to the swivel types. s.d. doesn't sell them or at least I've never seen them. are they reliable?

MXmaniac · 01-01-2010, 09:49 PM

I got 90* swivels from McMaster-Carr. They've got any size you need.

suville · 01-01-2010, 09:53 PM

So the 90's will clear even with the added thickness of the bolt in c-notch?

MXmaniac · 01-01-2010, 10:04 PM

I don't have a bolt in C-notch (mine is a pipe notch welded in), but here's a picture if it helps. I have a 1/2" to 1/4" reducer and a 1/4" 90* swivel.

tcb-1 · 01-01-2010, 10:19 PM

thanks for the pic Andrew! I'm curious about the fitting length too since I will be performing this same plumbing next week.

suville · 01-01-2010, 10:24 PM

Yea the pic helps somewhat but I'm thinkin that could be somewhat close by the added thickness of the bolt in notch so maybe 45's would work best, any pics of the front probly pretty difficult to get a pic of that one huh?[/I]

**lolife99** · 01-01-2010, 10:43 PM

sullville,...
now that you metion it,... I did swap out the rear fitting for straight ones.

I also running only 1/4" air line. Plus I put a "loop" in the line so I can connect the line to the fitting before I bolt the bag in place.

tcb-1 · 01-01-2010, 10:46 PM

yep suville, your right. I have the same setup as you; bolt-in notch. I think we may need to run a short pipe nipple directly out of the bag and then into a 90* fitting. iirc, the total thickness of the frame and the c-notch is close to .50" to .63". a nipple would get you past everything. I'll be watching this thread since I'll be performing this same task sooooooooon.

Doug,... I bet suicidedoors has them.
I ordered mine from Fastenal in town. Just make sure you get DOT fittings.

Here's another good site:

Well I rekin were both in the loop on this so looks like we'll be copy cattin!I cant afford to be trial and error so I sure preciate ya'lls input. BTW Doug preciate your support of POW_MIA's I'm a Nam era vet it means a lot to those of us left,here in Idaho were still hopin our boy from Hailey makes it out and back.

tcb-1 · 01-01-2010, 10:59 PM

suville, Sir you do not have to thank me, it's the right thing to do. We owe everything to our vets. I did not serve, but I truly appreciate your sacrifice and to those who sacrificed all. I salute you Sir. I fly the flag everyday for my friends who are in the Mideast, but it symbolizes ALL those who served.

Keith I'll try s.d. next week, but we have a McMaster Carr locally (and my company has a corporate account, YES!). suville and I have to clear a bit more metal than the weld in c-notch folks. like I said, I'm envisioning a short nipple to clear everything, then a swivel to get the exit in the proper location. bags get here next week, so this thread is close to my heart!

Sorry I don't have any shots of the front, I'm using coil springs in the front. The rear is a manual-fill setuip so it's essentially a static drop. If it were me I would use 45s just to be on the safe side, but surely someone on the board has a bolt-in c-notch with bags so I'll let them chime in.

By the way, McMaster-Carr also has 45* swivels. That may be just what you need. I can spend hours on their website...

**lolife99** · 01-01-2010, 11:34 PM

Doug,... here's a picture of my RE-7's ready to install with straight fittings.
The straight fitings make the bags mount easier.
(and possible since I used very flexible 1/4" line)
I'm not sure if you could use straight fittings with 3/8" or 1/2" air lines.

tcb-1 · 01-01-2010, 11:50 PM

I think you could still use a 1/2" pipe nipple with an 1/2"-14 npt to get some extra height, no?

**lolife99** · 01-01-2010, 11:55 PM

If you use a 90 degree fitting,... you need a frame hole big enough to get the "elbow" of the fitting thru it. But you are correct the pipe niple will help.
You just may have to connect the air line after the bag is installed.

Depends on the airbags too. I have Airlift Dominator 2600s and they don't have the studs on top like your RE-7s do, so I can attach the 90* elbow to the bag, and angle the bag so it goes through the hole in the frame. Then the bolts go through the frame and thread into the top of the airbag. The hole in my frame isn't big enough for the elbow to fit straight up through, you have to snake the elbow through the hole and maneuver the bag into place. Your RE-7s look like they have to slide straight upwards into place, you can't maneuver them any to snake the elbow through the hole.

My RE-7's didn't come with studs,... I added them.
Plus these were installed on my blazer,... where removing a "bed" wasn't an option, like on a pickup.
I did this to make it easier to install the nuts since everything was done by "feel" using just one hand up in that portion of the frame.

**kev2809** · 01-02-2010, 06:05 PM

definitely use 90 degree fittings if your using 1/2" line, that stuff is a ***** to bend. i have the dominator 2600's and ordered 45 degree fittings and it was a pain in the ass to get my airline inside the framerail to connect it. i installed the fitting to the bag before i bolted it up, that way i didnt strip anything and i had more room to work with.
