The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 20 units of a pressure gauge (NSN 1H-6685-003246003-X5) under a presolicitation notice. The procurement is set aside for small businesses, as indicated by the Total Small Business Set-Aside (FAR 19.5), and the contract will be negotiated with only one source due to the government's inability to reverse engineer the part or obtain the necessary data from additional sources. This equipment is critical for measuring and controlling pressure, temperature, and humidity, which are essential functions in various defense applications. Interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of the notice, with proposals being considered for the procurement process. For further inquiries, Amber C. Long can be contacted at (717) 605-4657 or via email at AMBER.C.LONG3.CIV@US.NAVY.MIL.
