What hose will survive the heat coming right off of the york? I've got 1/2" Female NPT and need about 2-3 feet?

I don't think my 3/8" air hose will last, and I'd like to go larger diameter anyway, at least for the first section.

what should I use, and where in Folsom/Rancho/Sac can I get it?

Oh, cheap would be good too :D

I am just running regular 1/2" airhose from the york to my airblock.Think it is speedair brand. I also am running 1/4" airhose to my air fittings. I just bought a good airhose & cut it in half. Has worked fine for years. Some friends of mine are running napa hose. Sorry, but don't know the napa part # .

Page through your phone book and find a rubber and hose shop, most likely in the "truck repair" or "supply section" Have them make up a hose for you.

I had this one made up 9 years ago, and it's still working just fine. Paid $19 for it. They reused my fittings at the compressor and installed a 3/8 male NPT fitting on the tank end.

And your right, standard airline will not last, or at least did not for me, I tried two brands, a few times when I first put mine together, they all blew out in just a few uses.

I ran the stock A/C hose that came on the compressor. I cut it as far back to keep it as long as I could and attached a barb fitting that necked it down. I then used 3/8 copper line and compression fittings to run it to the tank.

I bought 60' of 3/8" blue air hose from Walmart for $10-ish.

At first, I cut the hose and ran it right off the output fitting. It got hot, and didn't last too terribly long.

I now have about 2-3" of the flexible hose that just makes a coupler from the barb on the compressor output to some galvanized pipe. The pipe then goes out 4-5" and then a 90-deg and a little more metal pipe before becoming flexible hose again off to the fender and the pressure valve, quick disconnect, etc.

That's minimized the problem.

The hoses last 3 years or so now. Not bad for living under the hood of a Scout.

Heck, I think the hoses have outlived 3 engines. :D

Hydro hose, alot of the stuff is rated for heat.

The NAPA out inthe sticks around here will do custom hoses for tractors and stuff, no problem and cheap.

stock a/c hose and a barb fitting and it works great to the regulator and then I have just elcheapo hose from there on.

well I don't have the factory hose or I suppose that would have worked.

Will copper compression fittings hold up to the vibration??? That would be easy to make and cheap.

Hmmm...

I use regular automotive heater hose.

i also had the same problem, air hose would not last long at all. i found a piece of washing machine hot water inlet hose laying around and used a piece of it. its been installed two years now and is just now starting to get soft from the heat. of course hardpiping it would be the best......

I used about three feet of hydraulic hose from NAPA. After that I run about 7 or eight feet of regular airline to the oil/air separator. I had to run this extra 7 or 8 feet becuase my separator kept melting. I just run the extra line around the battery tray a couple times (Optima, no leaky acid). Works great for me.

I use a piece of hose for a high-pressure steam cleaner. It's rated for several hundred psi at 350°F or so. I got it from McMaster and it was pretty cheap. Also got a quick disconnect from them to connect to the compressor that is rated for 300°-400° as well. It uses some kind of neoprene or nitrile seal or something instead of what's in a regular air-line disconnect.

Go to Www.onboardair.com email brad and ask whe he recommeds.. I am sure he has been asked this question alot.

Go to Www.onboardair.com email brad and ask whe he recommeds.

BTDT. Kilby suggests "good hose". He has goodyear hose, but he has said he wishes it had a higher temp rating even though it hasn't failed him yet. (its rated to 200F).

anyway I called Napa back and they do make hydraulic hoses, and they do it while you wait:) First time I called I think they were busy or I got the wrong guy, or I called the wrong napa...

thanks for the ideas.

hey dan, go to tubes and hoses or someplace, and get a number 8 ac hose. Thats why my friend did on his york, and thats what ill be doing on mine, It can withstand the pressure and the heat. Its what it was designed for... or use stainless braded. another friend has his entire OBA from york to manifold he made, to the taknk, all stainless

I have steel braid from the compressor all the way to the QD's as well. It was scrap stuff, so I have no idea what it would cost to do it. 1/2" (double walled:D) all the way to the back of my ZJ into a 6 gallon tank, then it breaks down to 1/4" stainless for everything else. My system will hold air pressure INDEFINITELY, and I don't foresee any meltdown issues in the future. Cool thing about it...there are absolutely NO BARBS ANYWHERE when done this way. Everything seals nicely. Here's a link to my pics (http://communities.msn.com/HUFDADYSAlbum/shoebox.msnw?Page=1), good luck.

got any more scrap spare stainless braid sittin around, I'll be more than happy to take it off your hands for a :beer: or 2 :D

You know, if I had anymore of the 1/2" double wall stuff...I may very well take you ya up on it. That stuff is a PAIN in the arse to route, and I won't even get into the fine art of getting the fittings on that stuff:mad: Talk about pissed! I think it's rated some ungodly psi...~25k or more I believe (military aviation stuff:D). The 1/4" was a breeze though. The good thing about it, is that I won't ever have to mess with it again, it's DONE! :D

I'm using braided stainless line, basically the same thing used in stainless break lines, but bigger.

That's the same thing I did. I took the A/C hose to The Air Tool store in Sac and had them crimp on a barbed fitting and then when copper from there to the tank. Holds up great- even when I got the compressor smoking once! :D

Just grab a hose out of a Pick-n-Pull since you dont have one. Any one will do. The fittings appear to be standard for all the A/C stuff. :)
