SSJ - Monel K500_Redacted.pdf

This is a Single Source Justification (Simplified Acquisition) document for the procurement of Monel K-500 tubing by the Air Force Test Center/AFTC/PZRB at Edwards AFB. The requirement is for high-pressure, oxygen-compatible tubing for use in the oxygen systems of the Multiscale Rocket Engine Test (MRET) Facility, with specific requirements including UNS N05500 alloy, twelve 12-ft stock lengths (approximately 144 ft total), 2-inch outside diameter, and 0.5-inch wall thickness.

The document justifies sole-source procurement from Metal Suppliers Online after extensive market research including an RFI on SAM.gov, outreach to 30 potential vendors through ThomasNet, and communications with commercial counterparts. The previous supplier, All Metal Sales Inc., is no longer viable due to extended lead times. Multiple other vendors were contacted but unable to meet requirements, including Michlin Metals, Continental Steel, and several others. The contract action was documented on February 4, 2025, and demonstrates compliance with FAR 13.106-1(b)(1) for single-source justification. The estimated contract cost is redacted in the document.
