On the S-3D, the turbopumps were mounted on the missile frame, forward of the engine's gimbal bearing, which meant that the high-pressure ducts had to allow for the movement of the engine; to this end, each of the propellant high-pressure ducts incorporated two of these braided-covered bellows sections to provide the required flexibility.

This particular section is located on the LOX high-pressure duct, just upstream of the main LOX valve.
