Will this flex-hose connection work with 120psi ???????

[bucannon]

In ECON today i understood what we were talking about so i decided to draw up plans of what i wanted my onboard air compressor with two quick connects to consist of.

im not using the compressor for suspension or a locker but i figured the guys in the suspension thread would know the most about air systems.

after i spent alot of time at home Depot the other day i realized that using compression fittings would not work for 1/4 or 3/8 threaded air chucks with the hose diameter i want due to coarse thread vs fine thread ect...

so i thought of a plan that would work with what i had available and i wanted to know if it would work with the 90-120 psi range of the compressor ill be buying with harness for $177 (ARB CKSA12) i know it is only supposed to used for lockers but all i need it for is to inflate a stock 29" tire, it will be better than the plug in one i have in the toolbox haha



Will this connection work with two clamps? will it hold back 120psi?

Will this hold the pressure???



I answered my own question by researching "air hose repair kit"
and i found the picture below, which is for air hose that handles 150 psi.

so my 90 to 120 should be fine on a similar type connection.

I really prefer using DOT air line and fittings on my vehicles.
Several of the suspension vendors should be able to hook you up.

If it was me i would buy a full kit from like http://www.viaircorp.com/oba.html Some of forum vendors sell VIAIR probably get you a discount and have something you can trust to work and not break on you.

If your only using it for airing up after going off road, I would consider a pre-assembled hose that has compressed fittings.

I have to agree with lolife, hose and gear clamps not all that reliable. Use what they use on heavy vehicle air brake systems.
Have a look at this post, and particularly where to get tubing and fittings. The push on NTA/DOT fittings are very easy to work with, and look great. Spend $10 on a tube cutter, it is important that the tube is cut square.

This is a great resource, im surprised that i didn't look in my summit catalog right next to my porcelain throne, must have been too busy reading the new issue of HOTROD talking about the 2012 copo camaro haha.




but i certainly agree that DOT lines would be the best option. I would prefer a larger diameter tubing to allow better flow of air, I think of it as if im getting an edelbrock intake instead of a stock one.

The truck i'm installing this system on is a daily driver mostly on road and that occasionally gets a nail in the tire. so i feel that the low cost connections that hold tight on the frame rail will work well with this braided hose if i make sure that the hose is run across a cross-member on the frame and use chafing gear on the air hose

being a sailor has made me learn to use what i have available. although i could order this stuff from summit and wait 3 days. i can go to the hardware store and buy this stuff off the shelf for half the cost while supporting a local business.

whatever i end up doing, i will post pictures.

DOT fittings and tubing are available in 1/4, 3/8, 1/2, 5/8, no end of fittings and adapters. Also look for what is called an anchor coupling, or terminal bolt to go through the frame, or any panels. you can mount it in the frame or panel, then thread in fittings on either side, makes for neat job.

Thanks this looks like what i need!

You mention fine thread vs course thread fittings, so a little info for you.

Nearly all fitting you want to use with air pressure are NPT (National Pipe Thread). You can identify them by the very slight taper to the male threads (overall diameter). This is to allow it to seal against the female side by "wedging" itself together as straight threads would not allow that to happen. Also, the sizing is not by the thread diameter as normal bolts are, it goes based off of piping inner diameters, so a 3/8 NPT fitting tends to have a 3/8 hole and be just under 11/16 O.D. (.675 actual).

I don't trust clamps and nipples to hold up long term in a vibrating vehicle. Look in the tool section and see if you can find a coiled air hose and attach that to the compressor output. Also, careful that the output of a small compressor is very hot so cheap hoses don't always last mounted directly.

Better solution, look around the hardware store for hydraulic hoses and buy a long enough premade one to go to your fitting on the frame. I buy mine at Fleet Farm and they're pretty cheap, pre crimped and will last.

[CRGRS 66]

it is a little more expensive, but for a permanent solution for coming off of the compressor that will take the heat, and absorb the vibration, go to your local hydraulic distributor and ask for teflon hose, it has a stainless outer braid, and looks pretty too. They will normally make you a hose to the length you need while you wait. Always good to have a swivel on one end, go with a JIC swivel, and a JICxMNPT adapter. Teflon is good to 450F, hydraulic hose will last longer because there is more meat there, but is not rated for the higher temperature. There is a blue rubber hose that is rated for higher temperatures as well, but for a small bore, short hose the teflon/SS braided should not break the bank. I am in Canada, but could hook you up with a Parker distributor anywhere in the USA.

DOT line goes much bigger than anything you'd use so size shouldn't be an issue , and you can get things like bulkhead fitting etc for them at most diesel truck supplier or plenty of places online.

Hell how much do you need? I have a bunch of DOT line is different sizes and misc fittings from when I was into bagging etc.

I dont need much, just enough to run the hose from the compressor to both frame rails. ive got to do some more research into what sizes i need.
