40FP-40ORF FLANGE CODE 61

Description & Features

Designed for 2-1/2 inch hydraulic line connections, the 40FP-40ORF Flange Code 61 is a male O-ring face flange fitting manufactured by Brennan Industries. It accommodates a 2-1/2-8 NPTF thread (Dimension G) and carries a flange size of 2-1/2, making it well-suited for high-pressure hydraulic circuits requiring reliable, leak-resistant face sealing. The O-ring face flange design minimizes the risk of leakage at connection points, a key advantage in demanding fluid power applications.

Dimensional references include a bolt hole drill size of 0.531 inches (K1) with a 1/2-13 thread (K2), and a pilot diameter ranging from 2.995 to 3.005 inches. Part of the Brennan 1927-61 series, this fitting is built to Code 61 flange standards, which are commonly specified for medium-pressure hydraulic systems. The male configuration suits direct mating with compatible Code 61 flange ports and manifolds.
