The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure six units of a differential pressure gauge (NSN 1H-6685-016260399-X5). This procurement is critical as the gauge is used for measuring and controlling pressure, temperature, and humidity, which are essential for various military applications. The government intends to solicit and negotiate with only one source due to the proprietary nature of the data required for this part, and interested parties have 45 days to express their interest or submit proposals. For further inquiries, potential vendors can contact Jason A. Piechowicz at (717) 605-3515 or via email at JASON.PIECHOWICZ@NAVY.MIL.
