Most of the plumbing fittings are $$$ now. I use this product to bend some copper pipe 3/4 , not bad using this product for my 1st time , tip -use some lubricant in order to make bends more smooth. I tried with pex too it's helps a lot if you need to bend some but pex is flexible is not going to keep the shape on a 90 degree It works great with hard pipe or copper pipe.
