Ask A Question

Description & Features

Designed for converting between NPT pipe thread and JIC 37° flare connections in a single inline fitting, this Steel Adapter, 1/4-18 Male NPT Branch To 1/2-20 Male JIC 37 deg Flare Run, Tee from Brennan Industries routes a smaller-diameter NPT branch off a larger JIC flare run. The tee configuration accepts a 1/4-18 male NPT branch connection alongside dual 1/2-20 male JIC 37° flare run ports, making it well suited for hydraulic circuits that require a branch tap at differing thread standards.

Manufactured in steel, the fitting measures 1.09 inches on the A dimension and 1.05 inches on the B dimension, with a tube O.D. of 0.31 inches. The male JIC 37° flare ends provide leak-resistant seating characteristic of SAE flare-style fittings, while the male NPT branch delivers a reliable threaded connection for compatible hydraulic line components.

Question by: Jimmy M on Jun 18, 2025, 10:30 AM
trying to replace a tee i got stamped 05MJ-05MJ-04MP. is that the same thing as this part
Answer by: Customer Support on Jun 19, 2025, 8:14 PM
Match the thread callouts and it lines up. This tee is a 05MJ-05MJ-04MP configuration, with 1/2-20 male JIC 37 degree flare on the run ends and a 1/4-18 male NPT branch.

So this is a tee fitting, right? Just want to make sure it'll work with my setup.

Correct, this is a tee fitting designed with a 1/4-18 Male NPT branch and a 1/2-20 Male JIC 37 deg Flare run. It adapts pipe to 37° flare connections.
