Bulkhead - ebb and flow

This is an 3/4 inch PVC to 5/8 inch vinyl tubing bulk head. threading is short due to it being used on an indoor aquaponic system storage tote grow bed. The Gasket was made using a tube of silicon caulk and some paper. There are two different nuts you can use depending on if you plan to use 5/8ths inch vinyl or 3/4 inch pvc. The threading needs to be printed at a .1 mm layer height so that it is as smooth as possible but you can print the rest at .2 mm no problem.I'm currently employing multiple bulkheads in my system for the siphone as well as a DIY overflow I made.
