This document is a Sole Source Justification (Commercial Only - One Source/Brand Name Justification) submitted by NAVSUP Fleet Logistics Centers in accordance with FAR 12.102(a).

The justification supports a sole source procurement for repair parts for the No. 2 Main Diesel Engine No. 1 FW Cooler, specifically one High Temp Fresh Water Cooler Plate Pack (Accu-therm Plate Pack), Part Number 749901. Competition is restricted to Paul Mueller Company (CAGE Code 1V224), a large business concern classified as the Original Equipment Manufacturer (OEM). The manufacturer point of contact is Alan Winter at 417-575-9202, awinter@paulmueller.com. The basis for restricting competition to a single source is that Paul Mueller Company is the OEM and retains proprietary rights and technical knowledge required to support Main Diesel Engine No. 2, which is classified as a critical safety item per COMSCINST 4490.1C NSC N7. The justification states that only qualified sources can produce and service these critical safety items, and only authorized field service technicians have access to necessary technical data. The document notes that improperly installed or deficient parts could cause system failure and equipment loss at sea, and that no known alternate manufacturer exists for compatible replacement parts. The contracting officer has certified that the statements and information provided are complete and correct and represent the minimum government requirement.
