hose, wire suppots and fastening

[Raider L]

When i was an aircraft mechanic everything inside the skin of a plane is either fastened, supported, clamped, or tied with a thing that keeps a hose, wire, steel or alum. line (tube) so that it doesn't chaff (rub)up against the thing next to it, or near something so that if it comes loose it won't damage the thing it's next to, or near to, above, or below a thing. Chaffing is the biggest concern because of what is called "harmonic vibration". Jet engines make a lot of noise but what you don't see is these tiny little, but very intense vibrations that will rip right through a hose or a wire's insulation, and will wear a spot right through a steel or even faster a aluminum line (tube) going to an engine component or something that has to do with fuel or electrics, or just as bad a hydraulic line (tube).
In your high end full race cars they are treated more like aircraft than a car. Even though we all use the blue anodized fittings which are good, a lot of times I see hoses pushed up onto a barb and clamped with a worm screw clamp, and zip ties or some other kind of fastening done to a hose or wires. You can go to most auto parts stores and look for what some call "insulated clamps" that are the aluminum bands with a screw or bolt hole at the ends that are bent back over itself and have a rubber padding over the band that does a better job of holding something if you've chosen the right size. You want it tight so the thing you are using it on doesn't slip or slide in the clamp. We called these "adel" clamps because a company called Adel made them for aircraft. Now, you could get the same clamp from a automotive supply place but here's the difference. Everything made for aircraft has to pass through a lengthy authorization from the FAA that this, whatever it is, can be used on aircraft. So most aircraft mechanics call anodized fittings, "AN" fittings because most all of those kinds of fittings have an aircraft nomenclature to it or military, and they are all called "AN whatever", like AN6-1/2".
In order to keep hoses or wires from rubbing on some part of the truck or car use a "stand-off" This lifts the hose or wire off some part of the truck to keep it from chaffing or rubbing up against the truck that could cause a problem later on. Here are some examples on my truck.

I found the "stand off's" in those special parts at Lowe's where all the screws and specialty fasteners are. Those drawers that hold all the different screws and stuff there's a couple of drawers that have all these different lengths and diameters of aluminum tubing. I don't know what else you could use those things for but they make perfect stand off's. Get some screws or small shaft bolts and get your hoses off the fender wells.

bare with me... this is NOT permanent i did it in short time with random stuff laying near me because theway the hoses routed when unsupported was uncomfortably low and close to the exhaust and if it wasnt to the exhaust it was something else. I really like your idea with the insulated hanger. So what does one order the hanger, that meets standards, under? I was thinking of this myself when i saw a bag of insulated pipe hangers for a house in a bag, but those would most assuredly degrade quicker. i especially like standing them off the fender, that was a nice touch. i might just do that tomorrow, might use a shorter bolt/spacer or make a hole in the fender to do it, but thats ok

McMaster-Carr is my resource for things like industrial Adel clamps and machine parts like standoffs.

If there is a sign or plexiglass shop near you, standoffs are used in the sign and display industry to mount like placards on a wall etc. In a pinch they might have some.
