The Department of Defense, through the Defense Logistics Agency (DLA) Land and Maritime, is seeking sources for a "Parts Kit, Seal Replacement" with National Stock Number (NSN) 2590-01-685-1150. The procurement aims to identify manufacturers capable of producing these components, as the current approved source is limited to Defense Maritime Solutions, Inc., due to the unavailability of competitive data and the impracticality of reverse engineering. This parts kit is critical for maintaining operational readiness in vehicular applications, and the DLA is soliciting responses from potential suppliers to gather information that will inform the solicitation process. Interested parties should contact Contract Specialist Travis Grafton at travis.grafton@dla.mil, and are encouraged to submit their qualifications and any relevant sourcing information by the specified response date.
