Which is better - straight air hoses or coiled?

[Txcomp]

My .02 is for straight. I have some coiled hoses that I use in my shop and they're forever getting snagged on something or tangled up on themselves. All of my coiled hoses are hanging over the end of one of my shelves collecting dust.

Many years ago, I had the opportunity to attend several Bendix Westinghouse training meetings. I was surprised when they said that the coiled hoses you see on semi-trucks restrict the airflow between the tractor and trailer. They recommended straight hose if possible (but you rarely see straight hose on a tractor-trailer anymore) Every 90° elbow is like adding an additional 10 ft of hose.

I have only used coiled when airing up offroad so cannot comment on straight vs coiled. But the hose and metal connectors get ridiculously hot after running the compressor for the 10 minutes it takes me to air up. I wonder if all the bends increases the heat?

Maybe, but only if the bends restrict volume/increase pressure

PVT = PVT

P = Pressure
V = Volume
T = Temperature

The ideal gas law is PV = nRT
And viscus friction is not included in the ideal gas law. Short answer is no, at the pressure and flux that would take 10 minutes to fill, no way.
But the ideal gas law does pretty good at why the T goes up.

I just got one of these at harbor freight for $20 and my coiled hoses ang manifold fit perfectly. I made my own setup for just over $200 counting the smittybuilt compressor

Well that will deflate them quite quickly.
Back on topic: I have found the coiled lines can kink and crack. I cobbled one together with "straight rubber hose" that can be attached to 2 tires at a time. It's more bulky than some but it works for me. I used the coiling hose in my XJ but I've had many kinked and cracked.

I guess I should have specified the box, not the gun. I have coiled hose right now but am thinking about going to straight hose. Like others have said, the coiled hose puts pressure on the fitting and sometimes it's hard to get them to stay put on the valve stem. Right now I'm using a cobbled together 4-tire system that works pretty well even considering I bought a cheaper compressor. The last time I went out my compressor took my 35's from 20 to 36 PSI in about 10 minutes.

Thanks everyone for the insight and experiences. Ordering the straight cables once the budget rolls in on Friday.

I've had the coiled hose Speedflate 4-tire system for a couple of years now. It permanently lives in the back of the Jeep, through both the cold winters and hot summers, and still looks and feels brand new.

I've used it maybe a couple dozen times, and have never had an tangling issues beside the hose grabbing the drawstring of the proved bag. I have no special way of stowing the manifold and hoses. I simply just start grabbing the far end of one of the hoses and stuff it into the bag, than disconnect the next Schrader fitting and stuff that section on top of the first, etc. Next time it's needed, I grab the fitting at the top of the bag, connect to the first tire, and the rest deploys tangle free as I walk from tire to tire.

I keep meaning to transfer over to a similarly sized NRA duffel bag that i have laying around, which doesn't have any drawstrings for the coils to grab.

The northeast is a wet environment, so keeping the hoses off the ground is nice. One less thing to clean, and no dirt getting into the fittings when the mud dries in the bag.

I have the coil version to keep it out of the dirt. That said, it does get twisted together easily and I "think" the inner airflow diameter is greater in the straight version. I could be wrong though.

Nice!!!

My Viair compressor came with a coil air hose. I haven't had any problems with it, it stows away conveniently.

Thanks John!

The only time I ever had a tangling issue with the 4-tire Speedflate systems coiled hoses, was due to how I previously stowed it, which was manifold first and followed by both hose legs. Ever since, I start stuffing it with the end of one leg and finish with the end of the other leg.

I also carry two 20' straight hoses for when I need some reach. I coil them up to slip into an ARB carry case. They tend to want to tangle and kink unless I keep twisting the quick disconnect end as I stretch it out.

Not saying one is better than the other, but just sharing my experiences.

During my years at the repair shop, we used to always stow air and water hoses in a figure 8 pattern vs rolling them up in loops. This prevented tangles because the 8's offset the twist that naturally happens when coiling in circles.

Pardon the rambling. My mind just got wrapped up in it.

It's all good man, I love talking about trail gear.

Sometimes I fight with my 20' hose at the house. I forgot all about the figure 8, thanks for the reminder. I remember people doing that with long extension cords too.

Yeah, I don't know if one hose is necessarily better than the other on the trail, as of right now I prefer my coiled hose. It seems fast and easy. I don't Carry an extra hose but I'm thinking I should. On my list.
