Detail of the closure on the low-pressure oxidizer turbopump inlet.

The black, hexagonal plug with the white center near the top is a desiccant indicator; the white label under it reads "Change Desiccant when <symbol> is pink" and "Do not remove plug."

The part number on the darker cover at center begins "RK395-1", but the remainder is unreadable.

The overall part number, visible just above the brown "Rockwell International Rocketdyne Division" sticker near the bottom, is "RK395-44112-001".

The white sticker at lower left reads "Do not destroy/Rockwell International."
