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

Answer by: Customer Support on Dec 8, 2025, 6:33 AM

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.
