12MP-12MJ BULKHEAD STRAIGHT

Description & Features

Manufactured from straight steel, the 12Mp-12Mj Bulkhead Straight is a dual-thread hydraulic fitting designed to connect Male Nptf and Male JIC SAE 37-Degree Flare lines through a panel or bulkhead wall. Thread B1 is a 3/4-14 Male Nptf connection conforming to SAE J476, while Thread B2 is a 1-1/16-12 Male JIC SAE 37-Degree Flare conforming to SAE J514, making this fitting suited for mixed-thread hydraulic assemblies where both Nptf and JIC connections are required at a single transition point.

Part of the Brennan Industries 2706 Series, this fitting has an overall length of 2.920 mm and is subject to California Proposition 65 requirements. It is a practical solution for routing hydraulic lines through enclosures, frames, or mounting surfaces while maintaining secure, leak-resistant thread engagement on both ends.

Question by: Kirk H on Sep 4, 2025, 1:46 PM

So this fitting's got two different kinds of threads, right? NPT and JIC? Just want to be sure I'm reading that right.

Answer by: Customer Support on Sep 5, 2025, 9:42 PM

Correct. This bulkhead fitting uses a 3/4-14 Male NPTF connection on one side and a 1-1/16-12 Male JIC SAE 37-Degree Flare on the other, so you can connect different types of hydraulic lines.

got a bulkhead deal going through a panel, is this one the style that’s NPTF on one side and JIC 37 on the other?

For a mixed-thread pass-through, this fitting gives you a 3/4-14 male NPTF on the B1 side (SAE J476) and a 1-1/16-12 male JIC 37 degree flare on the B2 side (SAE J514), so you can transition NPTF to JIC through a bulkhead or panel.

fitting goes through a bulkhead panel, right? just want to make sure one end handles NPTF and the other end is JIC before i order a handful of these

Answer by: Customer Support on Jul 15, 2025, 4:31 PM

Correct on both counts. One end is a 3/4-14 Male NPTF thread built to SAE J476, and the other end is a 1-1/16-12 Male JIC SAE 37-Degree Flare conforming to SAE J514. The whole point of this fitting is to bridge those two thread types at a single pass-through point in a panel or frame, so you're not having to add extra adapters on either side of the wall.
