Attachment 4 - Brand Name Justification.pdf

This document is a Single Source Justification (Simplified Acquisition) for the acquisition of a Trailer Mounted Liquid Oxygen Tank Air Purging Unit. The procurement is for the Air Force, specifically for the FY25 437 MXS Purge Cart, with a Purchase Request Number F1M2X5044A001. The specific equipment is a Trailer Mounted Liquid Oxygen (LOX) Air Purging Unit, PIN# 791070-003, NSN: 3655-01-561-4006, intended primarily for purging liquid oxygen storage and transfer tanks for the JB Charleston fleet of C-17 aircraft.

Market research identified three vendors capable of fulfilling the requirement, but only one manufacturer is listed in the Defense Logistics Agency FED LOG system as an approved supplier. The procurement is limited to a 100% small business set-aside, with the solicitation to be posted on SAM.gov. The Technical Order 37C2-8-25-3 restricts the procurement to a specific air purging unit (GSU-62M) manufactured by Pacific Consolidated Industries. The Contracting Officer has determined that only a single source is reasonably available, with the justification document dated April 2021 and the contracting officer's determination signed on 20-Mar-2025.
