trying to swap out a flange and i keep seeing “12FORB-12ORF” on the old one, is this the same Code 61 style?

What size pipe does this flange fit? Just want to make sure I'm getting the right one for my setup.
Answer by: Customer Support on Sep 8, 2025, 6:47 AM
This flange is designed to fit a 3/4 inch pipe.
Question by: Bobby B on May 18, 2025, 9:04 PM
what's the thread spec on this flange and does the pipe size match up to 3/4 inch line?
Answer by: Customer Support on May 20, 2025, 6:43 AM
The G thread on this one is 1 1/16-12, and yes, the pipe size is 3/4 inch. It's part of Brennan's 1929-61 series built for Code 61 flange connections. The K2 thread for the bolt holes is 3/8-16, with a K1 drill size of 0.406. So if you're working with 3/4 inch hydraulic line and need a Code 61 fit, the thread and size specs line up for that application.
