Is that SKAREEF, Jason's old tank?
Looking great!
FYI....Sch 80 bulkheads require lager holes than sch 40. I do agree with using sch 80 over 40, better quality
O ring is on the wet side.
Dry no lube on gasket.
Disagree....
Gasket goes on the opposite side as the plastic nut. For most applications it will be on the wet side, but for some it could be the dry side, ie - glass-holes overflow.
Also, I always use just a slight amount of lube on the gasket. Too much is a bad thing, but just enough will keep the gasket from binding.
