TUBE ASSEMBLY-HYDR SYSTEM PRESSURE (P/N 390-521256-0009) - As Removed

The 390-521256-0009 is a hydraulic system pressure tube assembly that routes pressurized fluid between the hydraulic pump and pressure manifold in aircraft hydraulic circuits. Constructed from aerospace-grade metal tubing with AN/MS flare fittings, it maintains system pressure and flow integrity under operating conditions. Installation requires approved flare fittings and proper torque per the aircraft maintenance manual.

Verify compatibility with the aircraft's illustrated parts catalog before installation.

What is the TUBE ASSEMBLY-HYDR SYSTEM PRESSURE (P/N 390-521256-0009)?

The 390-521256-0009 is a hydraulic system pressure tube assembly that routes pressurized fluid between the hydraulic pump and pressure manifold in aircraft hydraulic circuits. Constructed from aerospace-grade metal tubing with AN/MS flare fittings, it maintains system pressure and flow integrity under operating conditions.

What hydraulic fluid type is the 390-521256-0009 compatible with?

Hydraulic component compatibility depends on the aircraft system design. Common aviation hydraulic fluids include MIL-PRF-5606 (mineral-based), MIL-PRF-83282 (synthetic), and Skydrol (phosphate ester). Verify the TUBE ASSEMBLY-HYDR SYSTEM PRESSURE against your aircraft maintenance manual for fluid compatibility.
