Midland Industries FF12FSAE Flat Face Sae O-ring Coupler

Product Description

The MIDLAND INDUSTRIES FF12FSAE is a flat face SAE O-ring hydraulic quick disconnect coupler designed for high-pressure fluid transfer in mobile and industrial hydraulic systems. The coupler features a 1/2-inch body with a 1/2-inch female O-ring boss (ORB) port on the secondary connection. Constructed from steel with a zinc-plated finish for corrosion resistance, it is rated to a maximum operating pressure of 4000 psi and handles temperatures from -65 to 250 degrees F. Licensed hydraulic technicians and fluid power specialists install this fitting in demanding hydraulic circuits where leak-free, flat face coupling is required.

The FF12FSAE is suited for residential, commercial, and agricultural hydraulic equipment where SAE O-ring boss thread interfaces are standard. The flat face design minimizes fluid spillage and air inclusion during connect and disconnect cycles, making it appropriate for environmentally sensitive work sites and precision fluid power applications. It fits within the SAE flush face ISO quick disconnect category and is well suited for mobile equipment, skid steer attachments, loader hydraulics, and similar service environments.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Relieve all hydraulic system pressure and depressurize the circuit completely before removing or installing any coupler. Inspect O-ring seals for damage prior to assembly and ensure mating surfaces are clean and free of debris. Torque connections in accordance with the system designer specifications and applicable industry standards for SAE hydraulic fittings.
