Description
The S2319-21 is a genuine Textron Aviation grommet that seals a joint or opening against air, fluid, or contamination. It is applicable to the Caravan or Grand Caravan EX, Citation CJ1 or CJ1+, and Skyhawk. It carries an export classification of ECCN EAR99, weighs 0.01 lbs, and measures 0.63 (L) x 0.63 (W) x 0.2 (H) in.
Because the S2319-21 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Across the Cessna Caravan, Citation, and Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Sealing components are sized and compounded for the fluids, temperatures, and pressures they contain, so the exact specified part maintains a tight joint. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
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. Cessna's single-engine Caravan turboprop, in production since 1984, is one of the most widely used utility aircraft in the world.
