DLA Aviation is conducting sources-sought market research to assess interest and capability for manufacturing NSN 2840-01-443-4245, a metallic aircraft gas turbine engineering seal, under NAICS 488190. The approved source is Stein Seal Company (CAGE 03673), part number SSCY12795; other contractors would need an approved Source Approval Request, and DLA does not possess complete technical data. Prospective sources should demonstrate capability for new manufacture, including component production, inspection, testing, preservation/packaging, shipping, and possible supply-chain/logistics support. The estimated requirement is a 2-year LTC base period with no options, and unit prices will be established at contract award. Based on responses, the effort may be set aside for small businesses or procured through full and open competition, with multiple awards possible.
