NSN 1680-012011689, cylinder assembly, r.

The Defense Logistics Agency (DLA) Aviation has issued a Pre-Solicitation Notice for NSN 1680-012011689, a Cylinder Assembly, R component. This sources sought notice is being used solely for market research purposes to identify whether additional companies are capable of manufacturing or legitimately obtaining this item. The government has explicitly stated that this is not a solicitation, not a request for offer, and does not constitute a commitment to award a contract; responses are purely voluntary and the government will not pay for preparation costs. The primary objective is to determine alternative sources beyond the current manufacturer, with the understanding that any responses received do not create obligations for the government. The response deadline is November 28, 2025, at 8:00 AM Eastern Standard Time, providing respondents with a brief four-day window to submit information regarding their manufacturing or supply capabilities.

No set-aside designation has been applied to this procurement. The item is currently manufactured by Real-Time Laboratories, LLC under part number 2082-1 05F and is used in connection with the KC-135 aircraft platform. This is classified as a source-controlled item, which means that DLA cannot independently approve alternative sources; companies interested in qualifying their products for future acquisitions must directly contact the Design Control Activity specified on the source control drawing. No contract award value, budget range, or specific quantity requirements have been disclosed in this notice, as the market research phase precedes any formal solicitation activities.
