The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking to procure five units of the industrial fluid heater, identified by NSN 7R-4420-016670121-RQ, on a sole source basis from IPT (CAGE: 4KV02). This procurement is critical as the heater is essential for operational support, and the government does not possess the necessary data or rights to source this part from alternative manufacturers. Interested vendors must note that a Source Approval Request (SAR) is required for those not already approved to manufacture this item, and the procurement timeline will not be extended for SAR approvals. For further inquiries, interested parties can contact Michael J. Brown at (215) 697-3765 or via email at MICHAEL.J.BROWN43@NAVY.MIL.
