I'm in need of dire help, folks.
Trying to alter my radiator's filling point, and I can't seem to find a small radius aluminum 1" (ID) pipe with a 90 degree mandrel bend in it. Been searching high and low, and the only answer I've gotten so far is one local supplier who wants $180 for the 6" pipe.

If anyone knows, please, help a brother out!

Both are tubing. I'm looking for 1" ID pipe, which works out to 1.375" OD.

If it's for fill tube, why does it have to be such a specific OD/ID aside from having whatever cap flange you're using match up. Just flare some tube. How tight of an arclength are you looking?

 

Sharpe has $100 minimum.
A (straight) 6" length of 1" ID pipe is about $10...

 

I need a 90 degree bend, plus, I'm sawing off the fill top off my fill bottle and I need an elbow bend to join the two pieces.

 

why a bend? You can't just cut the tube at 45° rotate and make a 90°?

What is so complicated about this that it needs such a specific piece for a fill tube. Please satisfy my curiosity.

Pressure, radiator, ease of filling

 

So ordering a relatively obscure small radius mandrel pipe which may cost more, versus just making a 90° elbow from a cheap straight pipe will make a huge difference if it's providing the same function? This still doesn't make sense unless the corner of the elbow itself provides some wacky interference.

Maybe take a piece of straight aluminum to an exhaust shop that has a mandrel bender?

 

erm mcmaster doesnt have this? You want like sch40 aluminum 1" pipe right?

Not sure if its been mentioned but have you tried mcmaster carr?

 

Thread of the day. Thank you.

 

Unfortunately, McMaster doesn't offer tight enough radius.
Thanks, though.

 

This is probably your best bet... Does it need to be mandrel for a fill point? Yeah it doesnt look as great but you really dont need the high flow rate mandrel bend for a fill point.
