The Defense Logistics Agency is conducting market research for the new manufacture of a Regulator and Hose (NSN 3655-01-517-0290, P/N KT-4856-1 & KT-4856-3), with an estimated requirement of 5 to 10 units. There is currently one approved source, The Entwistle Company LLC. This is a sources sought notice only, and there is no solicitation or associated budget information at this time. The government will use responses to determine if the requirement can be set aside for small businesses or if it will be full and open competition, potentially leading to multiple awards. Capability statements should address the ability to perform all manufacturing, supply chain, and logistics activities under a performance-based contract.
