The Texas Army National Guard intends to make a firm-fixed-price sole-source award for a carbon-fiber full composite pressure vessel (bottle only, Part B47437-1) compatible with Eaton’s Phantom Parachutist Oxygen System. Interested parties that believe they can meet the requirement and are authorized to distribute the item must identify themselves and provide clear and convincing evidence of their capability. Any information received will be used solely to determine whether to conduct a competitive procurement, and the decision not to compete is solely within the government’s discretion.
