Got a 5/8 tube line running through a panel and need a bulkhead fitting locked down tight, this the right locknut for that?

Question by: Harold T on Dec 6, 2025, 6:13 PM

For a 5/8 inch OD tube with a face seal bulkhead setup, yeah this is the one. The FS0306-10 is built specifically around that tube size, runs a 1-14 thread, and carries a hex of 1.312 inches so you've got solid wrench engagement when you're torquing it down. The 0.41 inch width keeps it compact enough for most panel installations without eating up a lot of real estate around the fitting.

trying to swap out a bulkhead locknut i’ve got, what thread and tube size is this one made for?

It uses a 1-14 thread and it’s matched to a 5/8 inch tube outer diameter.
