Quick Bulkhead Question

[Ereefic]

Need to order some bulkheads, just wanna make sure I order them correctly.

When it says 'threaded x slip', which side of the BH is which? I need the inside tank part to be threaded and the outside (where the nut goes) to be slip. Please help me understand. :)

FWIW, I haven't seen bulkheads with slip on the flange side and thread on the nut side. You should be fine. Even if it is reversed, you can just turn the bulkhead around and still get a good seal. Bulkheads work with either the flange inside or outside the tank. They just require that you put the gasket on the flanged side, NOT the nut side. Water travels through the threads. Don't make this common mistake.
