Trying to match up parts here, is this lock nut the one that goes with a 10 JIC bulkhead fitting?

Question by: Hugh M on Dec 15, 2025, 6:22 AM

For a 10 JIC bulkhead setup, this nut matches the common 7/8-14 SAE J514 male JIC 37 degree flare thread and it is sized for tube OD 5/8.

what tube size does this bulkhead lock nut work with?

Question by: Connie B on Oct 11, 2025, 5:41 PM

Built around a 5/8 inch tube OD, this nut pairs with 10 JIC fittings using a male SAE 37 degree flare thread. The thread size is 7/8-14, which follows the SAE J514 standard. If your line is running 5/8 tube and you need to secure a bulkhead connection, this is the right size.

What's the deal with that Prop 65 warning for California residents? Just trying to figure out what that's about.

Question by: Dwight B on Mar 2, 2026, 1:28 PM

The Prop 65 warning is there to inform California residents about potential exposure to chemicals that the state has identified as causing cancer or reproductive harm. It's a standard notification, but it's always a good idea to check the specific details if you have concerns.
