The 390-521237-0005 is a hydraulic return tube assembly that routes low-pressure fluid from aircraft actuators and manifolds back to the reservoir. This aluminum tube carries return flow through the filtration circuit for storage and system cooling. Installed in the return plumbing between working components and the reservoir, it completes the hydraulic cycle on general aviation and corporate aircraft.
Installation follows aircraft maintenance manual specifications and FAA AC 43.13-1B guidance. Superceded by 390-521237-0011.

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 ASSY HYDRAULIC RETURN against your aircraft maintenance manual for fluid compatibility.
Overhauled and repaired hydraulic components are pressure-tested per manufacturer specifications and include 8130-3 documentation. The TUBE ASSY HYDRAULIC RETURN is available in: As Removed. Contact us for test documentation on your selected condition.
