Hi guys.

I'm in the process of figuring out the coolant hose setup and radiator setup on the v8 conversion. I've got the radiator setup that I think I want and I found a decent lower hose setup that works with the engine and the radiator. Now I have to splice two hoses together. Samco hose sells some hose joiners which is temping to get but to make it permanent I was thinking of using a hose joiner with a heat shrink tubing heated over the joint.

I think it should work but does anyone else see any potential problems with using heat shrink turbing on coolant hose?

I'm looking at Mcmaster right now and they make heat shrink fabric sleeving which looks perfect for what I'm thinking about doing?

Shrink Ratio: 2 to 1
Shrink Temperature: 230° F
Temperature Range: -40° to +257° F

I went to a plumbing supply house and got the adaptor fittings i needed... 1.5" to 1.75" brass barbed fitting

I was going to use the fitting too but without clamps? I was thinking that the heat shrink tubing would create a seal that would keep it tight?

not sure how tight it would keep it .. i had smal small t balot clamps laying around i used

I have heat shrink hose clamps for radiator hose. I'll sell them to you at my cost (since we're all Audi guys). just let me know what the O.D. of the hose is.
