The outside threads of a bulkhead do not match plumbing threads. It is only there for the nut to screw on. I do know some fittings in the electrical department may fit them, but all plumbing should be connected to the internal portion of the bulkheads.

When designing a system, you three possible bulkhead choices:

1) Slip / Slip
2) Female Pipe Threads / Slip
3) Slip / Female Pipe Threads

My preference is #2 in most cases, and #1 as a back up. I never use #3.
