The FAAC 390422 Flex Hose 750 is a high-quality hydraulic hose designed specifically for FAAC 750 in-ground swing gate operators. This hose provides a flexible hydraulic connection between the pump-motor unit and the drive mechanism, allowing for adaptable installation layouts and minimizing stress on rigid piping. At 10 meters (˜?33 ft) in length and with an outside diameter of 5/16? (˜ 8 mm), it supports sufficient reach while maintaining dependable hydraulic performance. Constructed to meet FAAC’s standards, the hose is rated for the pressures typical in gate hydraulics and is made to resist wear, environmental exposure, and repeated motion. It’s an essential replacement or spare part for FAAC 750 installations, or when modifying the layout of existing systems.
Use this hose when installing or servicing FAAC 750 hydraulic swing gate operators to ensure proper flexible fluid routing.
Replace rigid sections or old hoses that show signs of cracking, leaks, or stiffness to prevent hydraulic failure.
Ensure the hose is routed so that there are smooth bends (no sharp kinks), avoiding abrasion, pinch points, or contact with sharp edges.
Make sure hose fittings are tightened to correct torque to avoid leaks. Use proper hydraulic seals or O-rings as needed.
Periodically inspect the hose for wear, rubbing, or external damage (sunlight, chemicals, etc.) especially where exposed.
When customizing gate installations (different layout, longer travel, etc.), this hose length gives flexibility; ensure no excessively long unsupported runs that could lead to pressure losses or flutter.
Preparation
Confirm compatibility: this hose is for FAAC 750 in-ground hydraulic swing operators.
Ensure you have correct fittings on both ends (pump side and drive unit side), clean and free from debris.
Routing the Hose
Plan the path from pump unit to drive unit: allow slack for motion, ensure bend radii are gentle (avoid sharp corners).
Secure the hose with clamps or brackets to avoid vibration or rubbing against structural elements.
Connection
Connect the hose ends to the hydraulic fittings, ensuring correct orientation and use of correct seals.
Tighten per manufacturer-recommended torque. Check for any hose twist or tension that may cause strain.
Bleeding / Priming
Once connected, bleed air out of the hydraulic system if required so that fluid flows smoothly.
Operate the gate through a few open/close cycles and observe for leaks or irregular behavior.
Testing
Check for leaks at all connection points under normal operation.
Confirm that the gate moves smoothly without jerks or dragging (which could signal hose restrictions or internal damage).
Monitor pressure if available (or feel for consistent hydraulic force) to ensure hose is delivering fluid properly.
Maintenance
Regular visual inspections (every few months or with annual maintenance): check for external damage or wear.
Replace ASAP if leaks, swelling, stiffening or other signs of deterioration are found.
Keep hydraulic fluid clean; contamination by foreign particles can damage hose inner lining or fittings.
Hydraulic systems are under high pressure. Always depressurize before disconnecting or servicing hose fittings.
Use protective eyewear and gloves when working with hydraulic fluid; fluid under pressure can cause injury if sprayed.
Ensure the hose does not rub against sharp or hot surfaces; abrasion can lead to leaks which can result in fluid loss or hydraulic system failure.
Avoid exposure to sunlight or harsh environmental chemicals which may degrade hose covering (unless hose is rated for UV / chemical exposure).
Replace any hose that shows signs of cracking, swelling, stiffening, blistering, or leakage — don’t wait for catastrophic failure.
Make sure hydraulic fluid used in the system is correct type and meets FAAC’s specifications; wrong fluid can degrade performance or damage components.
Ensure connections are properly sealed to avoid fluid leaks, which may pose slipping hazards or environmental contamination.
