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.
