The Department of the Air Force, through the 4th Contracting Squadron, intends to sole-source a contract for one Fuel Oil Heat Exchanger Flush Kit, Part Number HF11 AF F 15, to Hot Flush LLC under RFO 5.101. This specialized equipment is required for in-place cleaning of fuel/oil heat exchangers on F-15 aircraft to prevent overheating, avoid premature component failure, and minimize downtime, thereby enhancing aircraft operational availability. The system must be portable for flight line or shop use, operate using a solvent-free thermal oil system at 185°F to 195°F, deliver a flow rate of 4 to 80 GPM with regulated pressure not exceeding 80 PSI, and include a 4 to 100-gallon reservoir, 120 PSI air purge, automated reversing flow, and a multi-stage filtration system with 28-micron reusable, 10-micron disposable, and 50-micron reservoir filters. It must feature digital gauges for temperature, pressure, and flow, quick-connect fittings, an air hose with nozzle, and critical safety mechanisms including auto-timers, a dirty-filter shutoff sensor, and an Emergency Stop function. The sole-source determination is based on market research and official confirmation from the F-15 System Program Office that only this specific part number is authorized for use on the F-15 weapon system, with prior configuration coordination mandatory. The government is inviting potential offerors to submit evidence demonstrating that competitive procurement would be advantageous, cost-effective, timely, and not detrimental to mission readiness, though no solicitation exists and responses will not trigger a competitive bid process.
