I'm in the need of a hose with 1 3/4 ID on one end and 1 1/2 ID on the other. In this case a bottom hose going from radiator to water pump.
However, I HATE FLEX HOSES.
My Question: Do any of you know where you can get what I call "hose shims". Sometime ago I have bought "universal radiators" and they came with a "shim" or "band" that you could use on the radiator or water pump neck, to make a hose fit.
In my case I'd use a 1 3/4 I.D. hose on both ends and use the shim/band/adapter piece on the end where the neck is 1 1/2".
Any of you guys know of a place that handles something like this? The local Flaps just look at me like I'm crazy. Anyone, Jerry?, DG?, Deve?, Dave?, Tim?, anyone?
(I can find one with the right bends)
Thanks for any insight.

about having a radiator shop, if you can find one, solder a
matching fitting in the radiator?

I got the GM stamped radiator hoses from Chevy's of the 40's. Ran into the same problem...needed 1 3/4 I.D. and the hose was 1 1/2" I.D. Went to Lowes and got a PVC 1 3/4 " O.D. fitting and with some persuasion with boiling water and silicone grease was able to stretch the end onto the PVC fitting. Let it set and cool. Removed the PVC fitting and now the hose fits the 1 3/4" radiator fitting. Just an idea.

I've been down this road a few times. I guess I'm just looking for the "easy way out" as it seems I do the older I get!
I have also used two hoses with a reducer/adapter in the middle to "get there". Again, looking for simply solutions but they get fewer and farther between.

The kind folks let us walk into the area with the hoses and compare the samples we took with us. I did find a shaped hose with the proper ends(big for the water pump and small for the radiator). And like the idiot I am forgot to keep the part number. But the good news is it fit. Must be a chart of hose some where? I will keep looking.
