350-4-0180 – Textron Aviation Cessna Aircraft OEM Hose Assembly

Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 350-4-0180 is a genuine OEM, flight-critical, high-pressure flexible brake hose assembly, engineered for the landing gear systems of the Cessna Citation 500 series of business jets. This is not a generic hose; it is a precision-fabricated assembly designed to convey hydraulic fluid from the rigid airframe plumbing to the brake caliper under immense pressure. Featuring a durable Teflon (PTFE) inner tube, reinforced with a stainless steel braid, and terminated with permanent, factory-swaged fittings, the 350-4-0180 is built to withstand extreme pressures and the constant flexing of landing gear operations, ensuring the highest level of safety and braking reliability.

Key Features

• High-Pressure Capability: Engineered to operate reliably in a high-pressure aircraft hydraulic system. Its multi-layer construction provides an exceptional safety margin against bursting or leakage, which is essential for the brake system.
• Teflon (PTFE) Inner Tube: Features a seamless, smoothbore inner tube made from Polytetrafluoroethylene (PTFE). This material is chemically inert and impervious to all aviation hydraulic fluids (including Skydrol), and is non-aging, meaning it will not dry out or crack over time like a rubber hose.
• Corrosion-Resistant Steel Braid: A single or double braid of high-tensile, 300-series Corrosion Resistant Steel (CRES) wire is woven over the PTFE tube. This reinforcement provides the burst strength and protects the inner tube from abrasion and damage in the harsh wheel well environment.
• Vibration & Flex Resistance: As a flexible hose, it is designed to absorb the movements and vibrations of the landing gear during taxi, takeoff, landing, and retraction/extension cycles without fatiguing or failing.
• Genuine Textron OEM Part: As a genuine factory component, it guarantees the correct length, fitting type and orientation, and pressure rating required for a specific, certified application on the Citation 500 series. This ensures a perfect, stress-free installation.

• Primary Aircraft Models:
  • Cessna Citation 500
  • Cessna Citation I (501)

Applications

The 350-4-0180 is a flight-critical component with a singular, vital application:

• Brake System Hydraulic Line: Serves as the flexible connection that transmits high-pressure hydraulic fluid to the brake caliper, allowing the brake to function while accommodating the full range of motion of the landing gear.
• Mandatory Replacement Item: Hydraulic hoses are life-limited components and must be replaced after a specified number of years or flight hours, regardless of their apparent condition, to ensure safety.

Why Choose 350-4-0180?

A ruptured brake hose during landing or a high-speed taxi can lead to a complete loss of braking on one side, resulting in a serious directional control emergency. The Textron Aviation 350-4-0180 is the certified, factory-tested component designed to prevent this. Using a genuine OEM hose is the only way to ensure the part is fabricated using the correct materials and, most importantly, that the end fittings have been swaged with factory-calibrated equipment and pressure-tested to guarantee their integrity. For the flight-critical brake system, there is no substitute for a genuine OEM hose assembly.

The 350-4-0180 hose assembly is a critical component designed to handle both high static pressure and dynamic flexing. The smoothbore PTFE inner tube offers an extremely low coefficient of friction, ensuring efficient hydraulic power transmission with minimal pressure loss. The CRES braid is woven at a precise angle to provide maximum strength against hoop stress (the outward force from internal pressure) while still allowing the hose to be flexible. The factory-swaged end fittings are the most critical element; they create a 360-degree compression seal onto the hose, forming a connection that is typically stronger than the hose itself and is designed to be leak-proof and permanent for the entire service life of the assembly.

Note: This is a flight-critical and life-limited component. Installation must be performed by a certified A&P mechanic in strict accordance with the current Textron Aviation maintenance manual. The hose must be routed to avoid chafing and must not be twisted or bent tighter than its specified minimum bend radius. The end fittings must be torqued to the correct value.
