TUBE ASM (P/N 643616) - New Surplus

Part 643616 is a rigid tube assembly for aircraft hydraulic system plumbing. This component routes hydraulic fluid through the airframe structure, carrying return or supply flow between system components. Manufactured to aerospace tubing standards, the assembly features precision-formed bends and flared or flareless fittings for secure connections.

Used in Textron Aviation aircraft hydraulic line runs where rigid routing maintains system integrity and prevents vibration-induced fatigue. Installation requires torque specification verification per aircraft maintenance manual and FAA AC 43.13-1B acceptable practices.

What is the TUBE ASM (P/N 643616)?
