Hydraulic Filter Housing Repair & Overhaul

About the Hydraulic Filter Housing

A hydraulic filter housing is a pressure-containing manifold body in the hydraulic system that holds the filter element and provides the porting, bypass, and indication features needed to keep system fluid clean. Hydraulic fluid is routed through the housing and filter media to remove particulate contamination, protecting pumps, valves, and actuators, while an integral bypass and differential-pressure indicator manage clogged-element conditions. Typical degradation includes thread and sealing-surface wear, O-ring groove damage and external or internal leakage, corrosion and pitting of bores, cracking from pressure cycling and vibration, and worn or sticking bypass valve and indicator mechanisms. These conditions drive disassembly, inspection of bores and threads, seal replacement, proof and leak testing, and overhaul to restore pressure integrity.

Our Hydraulic Filter Housing Repair Capability

QTC repairs and overhauls hydraulic filter housing components to the original manufacturer's specifications under our FAA and EASA Part 145 approvals. Our engineers — including former OEM hydraulics specialists — perform teardown, inspection, cleaning, component replacement, functional and leak testing, and certification, and develop repairs for rejected and beyond-economic-repair (BER) hardware.
