Making nice tight bends in 1-1/8" Suction Line


How do you all make nice tight 90 degree bends in large (ie 1-1/8") suction line? Most tubing benders are well below this capacity. Would a conduit bender work out.

This tubing tend to be somewhat oval shaped and I don't want to cause restrictions or kinks.

TIA

Making nice tight bends in 1-1/8" Suction Line


Hi hennyh

The only real way to make a close bend is with a brazed on elbow. If you chose this method, when you get ready to cut the tubing. Take a Crescent wrench and fit it to the size of the pipe, put the Crescent wrench on the tubing and turn it around the tubing where you are going to make the cut, it will round out the tubing. I personally use a Imperial tubing bender for my tubing installations. The only draw back to it is I cannot make a close bend. I have to braze in an elbow when close bends are required. Hope this helps.

Good luck, Merry Christmas
Rusty

are you sure you need 1 1\8 copper line not to many units need that line size with 410a refrigerant could cause oil return problems

Yes, the soultion was 7/8" suction line and large radius fittings when tight bends were needed.

Thanks for the belated suggestions! It's nice to know someone still cares after all these years

this thread is too funny. A poster gets hollered at for necroposting and then the OP comes back, nearly 3 years after the original post and responds..

I think karma is looking kindly on mrairflow.
