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.

This cap fits a -16 JIC size, which corresponds to a 1-5/16-12 thread size. It's made to protect those flared fittings.

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

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

Answer by: Customer Support on Mar 14, 2026, 9:33 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.
