what thread size is this plug, and will it fit a standard -06 JIC flared fitting?

Question by: Troy H on Apr 24, 2025, 6:11 PM

The thread on this plug is 9/16-18, which matches the -06 JIC flared fitting standard. It's made to seat securely in that fitting and keep contaminants out while the connection isn't in use. Polyethylene gives it enough flexibility to install and pull off without much fuss, so swapping it in and out during maintenance or storage is straightforward.
