NSNs, item names and Federal Supply Class descriptions come from the Defense Logistics Agency's public Federal Logistics Information System data (PUB LOG, October 27, 2026 release). We show an NSN only when the government record lists our part number under the same manufacturer (CAGE code). Confirm the NSN and part number on your solicitation before you order.
