The FAAC 499449 Mid Flange is a genuine replacement flange component designed for the FAAC 422 hydraulic swing gate operator series. It is part of the interface or coupling group inside the cylinder assembly that connects or supports the moving internal elements. Manufactured to the same high standards as all FAAC spare parts, the 499449 Mid Flange ensures precision alignment, structural integrity, and long service life.
Compatible with several 422 models (e.g. CBAC, SB, CBC, CBCS, etc.), this Mid Flange is essential to maintain proper hydraulic function, seal integrity, and smooth motion of the piston/cylinder assembly. Without a properly functioning mid flange, hydraulic leaks or misalignment can reduce performance, increase wear, or cause failure. The FAAC 499449 is built with durable materials, precise machining, and meets the tolerances defined by FAAC.
This is a genuine FAAC spare part, manufactured to original factory specifications.
Material and machining tolerances match FAAC’s standards to ensure safety and reliable hydraulic performance.
Prior to installation, ensure the operator is powered off and hydraulic system depressurized to avoid injury.
Only trained or qualified technicians should replace internal flange components.
Disconnect power to the FAAC 422 operator and ensure hydraulic pressure is relieved according to manufacturer instructions.
Remove any cover plates or components necessary to access the existing mid flange inside the cylinder (refer to FAAC 422 manual).
Remove seals or O-rings around the existing mid flange carefully. Inspect and clean mating surfaces to remove debris or damage.
Position new FLANGE 499449 in place, ensuring proper alignment and that mating surfaces are flat and clean.
Install all seals / O-rings new (if applicable), tighten bolts or fasteners to the torque specifications provided by FAAC.
Reassemble any removed parts (covers, frenzied bolts), refill or re-charge hydraulic oil if required, check for leaks.
Test the gate operator through full cycle (open / close) to ensure smooth motion and that there are no abnormal sounds, leakage, or misalignment.
Always use FAAC-approved spare parts to maintain warranty and ensure compatibility.
Replace any worn or damaged O-rings, seals at the same time as replacing the mid flange to prevent leaks.
Inspect hydraulic fluid condition; if contaminated or degraded, consider replacing fluid.
Apply thread sealant / torque values as per FAAC specs to avoid over-tightening or under-tightening.
After replacement, perform a few manual and powered cycles to check performance under load.
