The higher the pressure the hotter the steam. I use my old ALL AMERICAN pressure canner /cooker to generate stream. It has a convenient 1/8 NPT hole in the top.
Thanks for making this video. The whole time you were using that zip tie I was waiting for the zip tied to melt or lose grip. So I started thinking about using some kind of pegboard with pegs to route the hose around. You could also just get a piece of wood with some nails and route your pipe around the nails and let it cool slowly or a poor cold water through it.
Steam starts at 212 degrees at sea level, but it can be much hotter under pressure. If your not looking for a reason to buy the nifty steam cleaner, you could just place the hose into pot of boiling water while it is restrained in the position you want. Leave it boil for a few minutes and then cut the heat and cold dip it or if you have time, leave it in the hot water until cooled to ambient temp.
Oh! I found it. I found the video. I didn't think it would be that easy. Usually finding videos without a link is a little difficult for me... I'm not a techy. (edit: Yep, this is a better way to bend rubber pipe (the heat gun wasn't so hot 😊. If you had pressurized steam, would that work better?)
So what is the optimal temp to heat the tube so that it keeps the shape? I needed to replace one tube in my car, unfortunately unavailable anywhere as a new part. It has a slight bend, about 45" but enough that the tube kinked and actually cracked in this place a few weeks later... I need to figure something out. Also I cannot find these springs anywhere near me and I must fix the car tomorrow as now it has a blasted tube. Would it work if I just stuffed some regular spring inside and boiled it for some time on the stove then let it cool?
Stuff it with something to keep it from kinking, boil it like you said for just a few minutes and then dunk it in cold water. If you need a 45 degree, bend it to approx 60 degrees when placing in the boiling water.
The largest spring I've found is one-inch - I've been trying to think of the best/economical way to form radiator hose. I wouldn't want to use sand. Maybe something like pennies?
@snake_eyes_garage i have been trying to find something economical as well. If i find something i will reply here or make a video about it. Thanks for your comment!
How about larger diameters? My current issue is a 1-1/2" fuel fill hose that I can't find OE or even similar. All I have is straight to start with, one end with maybe about 40deg and the other about 15deg - bigger spring, I guess...
This is great! I wonder what happens when the trans or steering fluids run through them. How hot do those get? Do they get hot enough to relax the hose and kink?
The springs obviously work, and some are saying you can use sand, but I am wondering if air pressure would also suffice... I think I may have to experiment with plugging up one end, then connecting the other to my air compressor, and perform some bending tests. I'm thinking 60-100 psi could work, but that is just a guess.... I have some Schrader tire valve stems that could possibly work to inflate the tubes just like a tire to a specific psi. Then couple that with a 1" pegboard array and you might just have a bending factory by placing batches in an oven until soft, then remove and quench.. The only caveat is how much extra pressure the heat would add, so maybe start out on the low side of a kink free pressure. (if it even works).
Does the hose hold the bend when 218* coolant passes through them? For any of the other hose needs I'm sure this is fine but what about those that get hot, or hot simply because they are near the engine?
They retain their shape. I have coolant hoses I've shaped and when I pulled them out after 3 years they held the shape. I also have hoses I bent for crankcase ventilation that sit 1-2 inches above the exhaust manifold, and those held their shape too.
@@thegaragehub I'll give it a try. I also have an idea of adding flex agent to paint when I paint my car and paint the rubber hoses too. That is what is done to the flexible bumpers.
Those spring style benders are pretty inexpensive. You can also use an extension spring on larger hoses. Even thick gauge saftey wire wrapped into a spring shape will help keep the shape with out the hose kinking.
If the spring is tight to get out, twist it to tighten the spring, it makes it easier to get out.

Those are great ideas!
At atmospheric pressure, steam is the same temperature as boiling water. May as well cook your hoses in a pot like pasta.
Just don't break the pasta in half lol
Steam starts at 212 degrees at sea level, but it can be much hotter under pressure.

Why not just submerge the Tube+Spring+Clamp into a boiling pot of water for a while, and then cool them all together under cold running water?
That is another way. Thanks for the feedback!
Because that's not fun, OK?
These are awesome idea's, thanks for teaching me something new
Thank you!

@@thegaragehub any idea what could I stuff it with out of household materials?

@snake_eyes_garage Check the description for a link to a larger spring that might work.

maybe try pre-bending pvc and using that as a form?
Brilliant! 👍
Thank you!

I havent had one kink yet, so thats good.

60 psi on a big tube can be dangerous if there's a risk of blowing the tube out.
This is good. I wish someone knew of a way to form nylon fuel lines without kinking.
That would be tough, nylon doesn't like high temp.
Can you bend heater hose?
Yes, it's important to cool them in cold water.
@@thegaragehub cool thanks 🙏🏼

What if I put the hose in boiling water instead of using steam?
Should work, take precautions.
Thats a useless work because these benders are too expensive. Think you have a real thick radiator hose, how expensive will this please?!
Thanks for the feedback! Glad it helped.
