The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 41 units of a valve assembly identified by NSN 1H-4820-015272249-X3. This procurement is critical as the government does not possess the data or rights necessary to purchase or contract repair of this part from alternative sources, making it essential to source from a single supplier under FAR 6.302-1. The valve assembly plays a vital role in various defense applications, and the government intends to solicit and negotiate exclusively with one source, although all responsible parties may express their interest and capability within 45 days of this notice. Interested vendors should contact Amber C. Long at (717) 605-4657 or via email at AMBER.LONG@NAVY.MIL for further details.
