trying to hook a pipe thread port up to a JIC hose end, is this the right adapter?

Answer by: Customer Support on Aug 2, 2025, 6:08 AM

For connecting a 1/2-14 male NPT to a 3/4-16 male JIC 37 degree flare, this straight bulkhead adapter matches those two thread ends.

got a panel i need to run a fitting through, does this one come with the locknut already, or is that something i'd have to track down separate?

Answer by: Customer Support on Mar 2, 2026, 6:02 AM

The locknut is included with this adapter. That bulkhead setup needs it to clamp securely against the panel, so Brennan builds it right into the assembly. You won't need to source anything extra to get a solid, stable mount.

got a hose end with a 3/4-16 jic on it and my port is 1/2 npt. is this the right straight bulkhead piece to tie those together

Answer by: Customer Support on Jul 30, 2025, 6:39 AM

For tying those two thread types together through a panel, this adapter matches a 1/2-14 male NPT on one side and a 3/4-16 male JIC 37 degree flare on the other, in a straight bulkhead style.
