Description & Features

Forged from steel, the 12MJ-12MJ-12FJS Tee Forg is a branch tee fitting designed for hydraulic line configurations requiring a three-port junction with mixed JIC connection types. All three ports share a common 1-1/16-12 thread size and conform to SAE J514, with two Male JIC SAE 37-degree flare ports and one Female JIC swivel 37-degree flare port, making it well-suited for inline branching where a swivel connection is needed at the branch outlet.

Steel forging construction provides consistent wall integrity and dimensional stability across the fitting body. Part of the Brennan Industries 6600-FG series, this tee carries a California Proposition 65 warning as noted for applicable buyers.

Question by: Merle F on Dec 23, 2025, 8:32 PM
Will this here tee fitting work if I need a swivel connection on just one of the outlets?
Answer by: Customer Support on Dec 25, 2025, 5:36 PM
Absolutely, this tee fitting has two male JIC ports and one female JIC swivel port, all with the same 1-1/16-12 thread size. That female swivel is what you're looking for when you need a rotating connection.
