#8 MJ X #2 MP ST.

Ask A Question

Description & Features

A straight steel hydraulic adapter from Brennan Industries, this fitting connects a #8 Male JIC (SAE 37-degree flare, 3/4-16 thread) to a #2 Male NPTF (1/8-27 thread) in a compact inline configuration. The JIC end conforms to SAE J514 and the NPTF end to SAE J476, making it a reliable choice for joining SAE flare lines to tapered pipe thread ports in hydraulic systems and fluid power circuits.

Rated to 6,000 PSI maximum dynamic pressure, the #8 MJ x #2 MP St. is suited for high-pressure hydraulic applications where a size-reduction straight adapter is needed between mismatched thread types. Constructed from straight steel, it offers durability in demanding industrial environments. California residents should note this product is subject to Proposition 65 requirements.

trying to hook a #8 JIC hose end up to a 1/8-27 NPTF port, is that what this adapter does?
Answer by: Customer Support on Dec 12, 2025, 11:09 AM
For tying those two thread styles together, it steps from a #8 Male JIC 37 degree flare with 3/4-16 threads over to a #2 Male NPTF with 1/8-27 threads, in a straight inline adapter.

what's the pressure rating on this fitting, and is it gonna hold up in a high-cycle hydraulic system?
Answer by: Customer Support on Jan 12, 2026, 7:37 AM
Rated at 6,000 PSI maximum dynamic pressure, it holds its own in demanding hydraulic circuits. Straight steel construction keeps it durable under repeated pressure cycles, so it's a solid pick for active industrial systems where pressure doesn't let up.
