PVC comes in extremely helpful with projects. Making a water tight seal between and securing it into place can be problematic. It will thread onto the standard 3/4" threading for PVC pipe. This is slightly different than what you can purchase at a store- it will thread all the way down despite the taper; hence, it requires a ruber washer for a water tight seal. I have used this on two different projects and it has worked great. I used it to rebuild the drainage system for an AC and then for an automatic watering system for plants outside. Worked great for both parts. Simply apply a rubber washer.

This is a 3D Printed PVC Nut that I made using the thread generator from openscad. A very important feature when comparing it to something you buy at the store- it is able to thread all the way down. I have used it on a couple of projects now and thought it might be helpful. I have used it for A/c drain pan and Automatic plant waterring system. It worked well for both.
