Me and my off the wall questions I know 
I have a picture here though, I need to know what size of thread this is so I can locate an appropriate fitting to screw over top of it.
This is the piece that connects to the spraybar/intake for the 5/8" eheim installation set I & II. (Hose Coupling: 7444098)
Instead of connecting tubing to this, I want to find a PVC fitting of some sort that will allow me to connect rigid tubing instead, or clear PVC... in order to do that though I need to know this thread size lol.
