I am needing to purchase or have bent a piece of 18 gauge steel tubing that is 1 1/4" OD to roughly 105 degrees on a 4" radius. Below is a picture of the part I"m needing to replicate. I"m sure a muffler shop could do it but it would end up with a rippled look on the inside of the bend and I"m wanting it to look exactly like the original part which would have been done with a mandrel bending machine. I have looked everywhere for prebent tubing and the closest I have found is a U bend pipe made on 2 1/2" radius instead of the 4" i"m needing. Does anyone know of a place that I can get mandrel bent pipe done by these dimensions?? Obviously a 4" radius die will be needed. Thanks in advance!
