The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support Mechanics, is seeking to procure 14 units of a 6-inch valve assembly (NSN 7H-4820-016519554) under a presolicitation notice. The procurement is intended for a specific part that the government plans to negotiate with only one source, as it has been determined that acquiring the necessary data or rights for competitive procurement is uneconomical. This valve assembly is crucial for various defense applications, and the government emphasizes that interested parties must include their CAGE code in any solicitation requests. For further inquiries, interested vendors can contact Joshua Eshleman at (717) 605-6055 or via email at joshua.j.eshleman@navy.mil. Quotes must be submitted prior to the award date for consideration, and the government retains discretion over whether to pursue competitive procurement based on the responses received.
