Need a solution for high-temp air hose fittings with onboard arb in engine bay

[N9WXU]

FYI The replacement hose I used is this EPDM hose: Hose Link on Amazon EPDM is supposed to be good to -60F to 300F. Who knows how this hose performs at the crimps.

I would contact a local hydraulic line supplier/maker. They are going to have suggestions for the high temps in your area. Most of these dudes are pretty helpful if you catch them during regular hours.

Yeah I have a few of those around town (Hose Advantage Store). Was wondering if a local 4x4 shop like @Doetsch Off-Road maybe has options too.

I got the three foot stainless braided hose that ARB sells. Put my quick connect on my mirror cowl next to the FM antenna.

This is also a challenge in air ride suspension systems. Most compressors come with a stainless steel lead of about 12 to 18 inches to help dissipate heat and avoid this failure. I'd recommend adding a stainless lead that goes from your compressor over to your main inflation line. It will withstand and dissipate the heat much better.

If you can get a stainless steel brake hose maybe if you can find the correct adaptors or if A/N fittings would work for the hose. Those brake hoses are supposed to handle like 450-500* temps and hold a lot of hydraulic psi.

I had the same exact problem in Moab. Finished a trail and was filling up in direct sun. I have a leader on there now using this hose and then a quick connect to the Flexzilla. Seems to do the job. It has an internal mesh in the rubber and generally is stiffer and feels more robust.

I was airing up in Sedona this week and the airhose fitting connected to the ARB in the engine bay let go. The hose got soft and the compression fitting couldn't hold it under pressure and BOOM hiiiisss. The ARB gets hot, it's in a hot engine bay, phoenix and sedona are hot ambient temps...

Caveats and Info:
- I live in Phoenix... it's HOT (even in Sedona where this happened, was like 102º outside)
- Flexzilla hose with ColorConnex fittings plugged into the ARB single compressor quick disconnect
- 33" tires... I was down at ~18psi and bringing them up to 40-42. Blew after the final two tires were at pressure.

SO... I'm looking for options:
1. I could sell/tradein this single ARB compressor and get a double so it'd fill up 2x faster and be exposed to heat for less time. Expensive route.
2. I could find better connectors than those pictured? hard lines? braided? (pressure isn't the issue it's the heat so idk if braided do better?)
3. I find a commercial connector and hose whip to plug into the engine bay mounted ARB, long enough to connect to outside of the engine bay. Not sure what brands or stuff might work here... but planning on going to a commercial hose store and ask for ideas.

THOUGHTS? Anybody else have similar issues and find a good solution?
Also... going to carry some hose clamps from now on... juuuust in case.

(coincidence - a couple weeks ago i have a flexzilla water hose on the house... Similarly the compression fitting let go... I mean that's outside too so... Phoenix / Arizona heat destroys everything.. ugh)

@Tech Tim gave me a heads-up about this potential issue several months ago. I bet he can offer some good advice here.

Screw style hose clamps and pvc hoses suck. In my machine shop I switched over to rubber hoses and crimp hose clamps. Once you try thr crinp on you’ll never go back. As others have said a 3’ sst braided line should get you of the engine bay. You could probably get a full length braided reinforced line, but that seems a little extreme.

Hose clamp kit. Get what sizes you need and the tool.

really like the idea pf moving the connect fitting to somewhere else.

Stainless steel ARB hoses from @4x4TruckLEDs.com will serve you well.

Just had the same thing happen to me. ARB recommends using a manifold for this reason. They don’t recommend connecting the quick connect directly to the compressor output.

Cool place for the air chuck!
