Topic: wanted: 20' of 1-3/8" (35mm) radiator hose

Striking out online. Where can I buy regular bulk heater/radiator hose? Not interested in paying $7/ft for fancy blue shiny silicone stuff.

Re: wanted: 20' of 1-3/8" (35mm) radiator hose

What are you using it for?  Can you use pieces of metal tube connected with shorter pieces of rubber?

A Daly City NAPA store I go to carries bulk hose. The Petaluma NAPA is a good place for parts (our car was based there). Have you called them?

Needs to connect rear engine to front radiator. There's a proper tunnel under the car for pipes, but the old metal ones are all rotted/rusted. I could use some new metal tubes though, but nowhere to find the OEM ones. I wanted to minimize the number of hose clamps and connections if possible. If I were to go with metal tubing, what would I want to look for? Maybe that galvanized electrical conduit stuff?

I'll call around the parts stores and see what they say. For some reason I haven't tried that yet.

You are going to want to run hard line under the car.  Running soft line is asking for a pinch/cut/tear/wear hole and then you will never know from the cockpit.  Does the OEM brand exist anymore?  You've tried the dealership?  Rock Auto?  Possibly have some muffler tube bent?  Does the car have some sort of forum that you can hop on and ask about parts?

what are you worried about? galvanic corrosion?
In that case, why not put a sacrificial anode in the system -- say at the drain petcock?
In my car, I have an aluminum radiator, iron block and heads, and some brass fittings in the system. Placing something like this may be a way to minimize corrosion when running distilled water.

Just find a pipe that is a decently tight fit to the rubber.  No sharp edges on the ends where it meats the hose.  Something substantial enough that it won't deform under the clamp. Material doesn't matter much, other than to provide the strength to prevent deformation.  Run coolant in it every once in a while to prevent corrosion.

Also need to find a way to add a bead to the end so that it doesn't blow the hose off under pressure.  Use some type of forming tool, weld a bead, or at least add a few dimples.

Would this work? Lovin that price!

Maybe.  What is the ID of the hose you are using?  1 3/8?  Might be a bit snug, depending on the type of hose you are using.

FWIW, our mid-engine swapped golf has 1" electrical conduit as hard pipe running the length of the car.  Mind the zinc coating when you weld beads on the ends...

All of the straight sections in our system are conduit.  All the bends are the result of me going behind the counter of autozone and buying every radiator hose with more than 3 bends in it that was the correct diameter.  That's three elbows per hose, super economical!

That would work, but keep in mind that silicone hose does not like oil.  Softens the hose and can eventually lead to failure.  EPDM rubber would be the best, but harder to find in bulk lengths.

I made a DIY tube beader for our team copying something I saw on the Interweb. Worked very well on our aluminum and steel turbo tubes. It was a fast job using this.

Picture below. Saddle from 3" U-bolt clamp, big washer and an old vise-grip clone. Size down for 1" should work for the conduit.

That's an awesome idea! Can I borrow your tool for a few days next week?

This tool is fascinating.
If I understand it correctly, you stick the washer in and when you clamp down, that pushes the inside slightly out against the u-clamp saddle, right?
Rotate a few degrees and repeat, right?

How many times did you need to rotate and reclamp to form the full bead all the way around the tube?
I dont know when I'll need to do this on my car but I love a good DIY idea.

You are welcome to borrow it, but it probably won't fit in what you using for metal tube. My feeble brain says the washer is around 2". It probably only works on 3" tubing the way it's made.

Also, we don't go to Petaluma anymore, car isn't there now. You'd have to come to SF or Vallejo to pick up the tool..

It would probably take you less time to go to Maselli's (I love that hardware store and I have yet to tour the giant scrap yard), get the appropriate pieces, weld them together (JB Weld would probably work too). Then you own the means of production.

Also, Maselli's undoubtedly has the conduit too. It's one stop shopping.

I wish I could claim thinking of this, but not an original idea - idea came from the Internet.

Your description of how it works is dead on. I'm not sure how many times you have to rotate and reclamp because I didn't do the beading. Before I had a chance to use it, a teammate grabbed it to try it and just kept going. Finished all the beading. I can report it went fast.
