The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure 25 units of a pressure relief valve, identified by NSN 7H-4820-015991823-PP. The procurement is based on a sole-source justification under FAR 6.302-1, indicating that the government intends to negotiate with only one source due to the unavailability of data or rights necessary for competitive procurement. These valves are critical components used in various defense applications, and the government has determined that it is uneconomical to reverse engineer or purchase the data for alternative sourcing. Interested parties are encouraged to express their interest and capabilities within 45 days of this notice, and they can contact Alison E. Harper at (717) 605-4443 or via email at ALISON.E.HARPER.CIV@US.NAVY.MIL for further information.
