The discharge hose on the compressor gets very hot. How well so you think they will hold up in that application?
 
as well as it does on my H3, maybe better? the hose is air compressor hose - which is rated for 300 psi and 180* temps. Also, Steve (sgould) is running similar air hose for his system.... steve, what was it - you filled 4 tires in the space I filled 2? lol... twin Viair air compressors are quick, but good grief not as good as yours.

you bring up a point that people do need to consider, though. On my H3, the first hose was hose normally used for running garage air systems.... it didn't survive the first test.... it got hot and split. So, good question - and one that must be considered for any inflation system.
 
Not chrome please. How about a dull stainless like finish. Copper would be hella cool. I bet nobody else in the world has a copper bezel. That patina would look awesome against the right paint scheme.

well, if you did it - then it couldn't be cool :D

the bezel itself is already repainted black.... but I'm still not inspired... It's like what Judge Cardoza said "you know porn when you see it" .... I'll say "THAT'S IT!!!" when I see it.... the other thought is powder coat the bezel copper or some contrasting, shiny color.

2 tires? More like 1 1/2. It is fast. My only limit is the size of the tire stem and the inflator itself. I plumbed the entire system with a minimum of 3/8" diameter components. The quick releases are 3/8 commercial products. They are actually kind of hard to couple together. I used extra hose material to fabricate the hose I use to fill with and keep it in my trail box. It only necks down at the inflator with size adapters. I can cut pieces off this hose if I blow an underhood hose.

I'm running that compressor on my Duramax and my 40. My system uses a stainless braided hose 18" long and an aluminum junction block for gauge and pressure switch then 3/8" airbrake tubing from there to the tank. I have had the airbrake tubing hot to the point of leaking while airing up 8 tires in a row.
 
Is air brake hose reinforced? I don't know, while I did have my CDL for awhile - to say the training was lackluster would imply that there was training further then "you need to release the air brakes to move the truck"... since I worked for a very large beverage company, the certification test was done over the phone... no kidding.

So what's the heat rating on the braided hose? Hummer air compressor system

braided hoses running to two pressure controllers - so the compressors don't come on and once and blow fuses. The black box was rancho shock controllers - an utter POS and waste of money... as were the shocks...



twin water-proof Ip68 fans... see the blue hose, that didn't last a hour after this picture was taken. I replaced that blue hose with braided stainless line to the bumper


and the outlet on the bumper

This has worked for 3 years now... and filled countless tires... though I've yet to climb under and be certain that both compressors are coming on - I think on Sunday one of the compressors was only coming on intermittently. It's fine though, once the '40 (and 70k more miles) is done I'll be replacing my DD (the H3 now) with a diesel Colorado truck... that means all of this gear (winch, compressors, etc) are going on my wife's joke... errr.. JK.
and housekeeping - a good question was asked elsewhere. I used heat-shrink clamps for this - but didn't mention that the heat-shrink clamps require some form of barbed fitting...

  • Airbrake Tubing - Superior cold weather flexibility and abrasion resistance. UV and ozone resistant nylon. Meets or exceeds SAEJ844 (Type A - non-reinforced & Type B - reinforced). Meets or exceeds DOT requirements for use with compression fittings (NOTE: SAE does not recognize 1/8", 5/32" or 3/16" O.D. tubing for use with air brake systems).
  • Identified per SAE J844 & FMVSS No. 106 Brake Hoses, 49 CFR 571.106
  • Conforms to rigorous qualification and inspection testing which exceeds SAE and DOT requirements
  • Designed to operate at up to 150 psi in air brake systems
  • Resistant to attack by gasoline, diesel fuel and commonly used road and cleaning chemicals

  • Nominal O.D. - 3/8"
  • Nominal Wall - 0.062"
  • Minimum Burst Pressure (psi @ 75°F) - 1400
  • Minimum Bend Radius - 1 1/2"

Doesn't really state a temp or pressure rating
 
PFT Type A Heat and light stabilized seamless single wall extruded nylon tubing, available in sizes 1/8 (-2), 5/32 (-2.5), 3/16 (-3), 1/4 (-4) and 5/16 (-5). This tubing conforms to SAE specification J844 type A. The A refers to nonreinforced tubing. Temperature Range: -40°F to +200°F (-40°C to +93°C). Maximum Working Pressure: 150 PSI. Meets D.O.T. FMVSS 106 (Sizes 2 and 2.5 not listed in FMVSS 106).
PFT Type B
Heat and light stabilized seamless extruded nylon core reinforced with one open ply of fibrous reinforcement and a protective nylon cover sheath. The outer cover and core are fused to minimize leakage and maximize impact resistance and are always of contrasting colors. This tubing conforms to SAE specification J844 type B. The B refers to reinforced tubing. Temperature Range: -40°F to +200°F (-40°C to +93°C). -70°F to +200°F (-56.6°C to +93°C) for PFT-8B coiled air brake tubing. Maximum Working Pressure: 150 PSI. Meets D.O.T. FMVSS 106.

the yellow is the answer to my question.... I didn't want to spend $75.00 buying the standard, I utterly detest SAE standards because they charge you to even look at the testing method. At least with the Ip standard, you can see the test results without having to buy the "how-to" of the method.

the red highlight could be a problem on some systems... what I don't like about either is that it doesn't tell me whether or not the max psi and the max temp are exclusive or tested together. Quality air hose is rated to 300 psi.

thanks for looking that up.
 
mickem frickem... I put the rocker arm nuts in a good place, and have been tripping over them for at least a year... guess what?
yeah, I'll be buying new ones today

didn't get much done on the '40 yesterday - was distracted by something else
but I did get a bit on the master cylinder


and did get the valve covers off in my aborted attempt to adjust the valves

also gave some thought to this color scheme


anyway, it's all off to the blaster today
