If leakage is the only problem, you could do what I did. It seems to work very well. I used muffler band clamps to seal the joints. These are thin, wide stainless steel bands (maybe 2" or 3" wide) with grade 8 bolts at the end. You placed them around the pipe at the joint and then tighten the clamp. The steel cold forms around the joint making a very strong and sealed joint. Clamp force is spread and radial so there is no pipe deformation. Only issue is that you need eight clamps and they are almost $10 each.
