Description
The S2485-2 is a genuine Textron Aviation valve drain — a flow-control element for a fluid or pneumatic system. It is fitted to the Citation X, Skyhawk, Skylane, and Stationair. It carries an export classification of ECCN 9A991, weighs 0.01 lbs, and measures 0.8 (L) x 0.58 (W) x 0.5 (H) in.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S2485-2 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Cessna Citation, Skyhawk, Skylane, and Stationair aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Because it handles pressurized fluid or air, a component like this is specified precisely for its service — the right part keeps the system sound. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. Cessna's Citation line, launched with the Model 500 in the early 1970s, grew into the best-selling business-jet family in the world, spanning today from the light M2 to the super-midsize Longitude.
