The Navy intends to solicit on a sole source basis with Vacco Industries (CAGE 99517) for the repair of three aircraft vent valves (NSN 7H-4820-014836369), with delivery to DLA Distribution Norfolk, VA. Vacco is the Original Equipment Manufacturer and the only known source, as the government lacks data or rights to purchase from other suppliers. Interested firms not already approved must submit a Source Approval Request, though the procurement will not be delayed for approval. The contract will have a one-year duration and is issued under emergency acquisition authority; this is not a small business set-aside. All responsible sources may submit a capability statement for consideration, but the government intends to negotiate with only this one responsible source.
