The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure six units of a differential gauge, identified by NSN 1H-6685-014429036-X5. The procurement is intended for supplies that will be delivered to two locations: DLA Distribution in New Cumberland, PA, and DLA Distribution San Joaquin in Tracy, CA. These gauges are critical for measuring and controlling pressure, temperature, and humidity, which are essential for various military applications. Interested vendors should note that the government intends to solicit and negotiate with only one source under FAR 6.302-1, and all proposals must be submitted within 45 days of this notice. For further inquiries, interested parties can contact Jason A. Piechowicz at (717) 605-3515 or via email at JASON.PIECHOWICZ@NAVY.MIL.
