Description
The S2485-1 is a genuine Textron Aviation valve drain — a flow-control element for a fluid or pneumatic system. It is fitted to the Skyhawk and Skylane. It carries an export classification of ECCN 9A991.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the S2485-1 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Parts like this are shared across the Cessna Skyhawk and Skylane aircraft, reflecting how much structure and hardware these models have in common.
Fluid- and air-system components are rated for specific pressures, media, and fittings, so the correct part is essential to a safe, leak-free system. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Built by Textron Aviation, whose Cessna line was founded in Wichita, Kansas in 1927 and joined Textron in 1992, this part carries one of general aviation's most storied names. The Cessna 172 Skyhawk is the most-produced aircraft in history, with more than 44,000 built since 1956, and remains in production under Textron Aviation.
