Question by: Steve H on Feb 27, 2026, 9:29 PM
what exactly is this flange used for, like what kind of setup would it go on?
Answer by: Customer Support on Mar 1, 2026, 6:39 AM
SAE 4-bolt flanges are used to connect hydraulic hoses or lines to pumps, motors, valves, and other hydraulic components. The 4-bolt pattern locks the connection down tight and handles the pressure that standard threaded fittings sometimes can't. It's a real common configuration on mobile equipment and industrial hydraulic systems where you need a solid, leak-resistant joint that won't back off under vibration.

Will this flange work for a standard SAE 4-bolt connection?

It's designed to fit any standard SAE 4-bolt pattern. Just make sure the size matches your requirements.
