got a -16 JIC flare fitting here, is this cap the right thread for it?

Question by: Keith K on Jun 13, 2025, 11:53 AM

For a -16 JIC flared fitting, the thread called out on this cap is 1-5/16-12, so it matches the -16 JIC thread size noted for the cap.

what size fitting does this cap go on exactly, the 1-5/16-12 thread or something different?

Question by: Scott F on Mar 12, 2026, 11:52 AM

Same thread, no difference. The cap is sized for 1-5/16-12 threads, which is the standard designation for a -16 JIC flared fitting. If your fitting is marked -16 JIC or carries that same thread spec, this cap will thread right onto it.

That's what they're made for. The G-27 cap carries a 1-5/16-12 thread and is sized specifically for -16 JIC flared fittings, so you'll get a proper threaded engagement on the fitting end. Good call on confirming before buying in quantity.
