I would like some suggestions. I need to thread a 2" elbow. To get the clearance I need, I would need to tightened the elbow to end of its thread. That is not going to happen so I thought about cutting the threaded pipe to the length I need. I am concerned that I cannot screw on my elbow if I do that. Another alternative is to put alot of adhesive to the threaded pipe and glue it to a slip joint elbow. Which method will yield the most successful result?
