Lower radiator hose/pipe

Looks like I have a very small leak developing in the metal pipe that the lower radiator hose connects to on our 06 DD4 - it's right where the metal clamp secures the pipe to the frame.

Where does one find one of these pipes? TIA!!!

I read a thread awhile back on here of a company in the northeast that makes them custom. Other than that you can go to a muffler shop. Stainless would be a good idea. I think I was looking for radiator hoses for a 2004 dynasty when I stumbled on the thread.
In the interim a plumbing rubber boot should hold it. You'll have to remove one end or all of it to get a coupler on. Also cutting the pipe in half and using a 6 inch piece of radiator hose will fix it for awhile. It should be 2 1/4 inch od tubing. https://www.mishimoto.com/race/race-...al-piping.html

Me too !

My Windsor had a perforation at exactly the same clamp location on the lower tube. Perhaps galvanic corrosion. It was discovered during replacement of all flexible coolant hoses.

Cummins Coach Care discovered the perforation in the steel pipe, cut it off and welded a new length of tube (from NAPA) as a repair.

Thanks for all your replies/input! May be a bit of overkill, but when I get a chance to dig into the repair I may consider removing the pipe & replacing with a stainless steel pipe. I imagine I could take the old one to a muffler shop & they could custom bend the SS tube to match the old one. Thoughts?

Me either. I took mine out and sanded it, killed the rust and repainted it when I changed the coolant hoses. It looked good inside, the outside was pretty rusty.

There 'was' a business with a online store, that sold that pipe in stainless, including the drain petcock.
Can't seem to find it now.

2.25" Stainless Steel T-304 DIY Custom Mandrel Exhaust Pipe Straight & Bend Kit

The item above on eBay $130 . Very good quality pipe and enough to replace all the pipes on my ISL side radiator. You can set the pieces side by side and have two welds done or use short pieces of 2.25 hose and join the pieces. I had mine welded, kid's coach was done with hose joints. New constant torque clamps.

I had previously cleaned and painted with POR15 (good for 5 years) and the rust continued under the paint...not comfortable with that. The stainless looks good too!!

Thank you Twomed - great suggestions all!
