Review on QILIPSU Waterproof Adjustable Locknut Diameter: Ultimate Protection and Flexibility for Any Application by Eric Kim

This is a great replacement for junction boxes. I use them to run a pipeline because of the price. Just remove the sleeve on the end and the 1/2" PVC will fit snugly. Apply some RTV to the threads before you do this and it will waterproof. It's no code, but it's a lot cheaper.
