This Sources Sought market research seeks additional manufacturing sources, other than current approved source Alfa Laval Inc., for NSN items on the attached spreadsheet. Prospective alternate sources must provide drawings, specifications, and other data sufficient to show their product is equal to the approved item across design, materials, performance, function, interchangeability, inspection/testing, and other characteristics. DLA Weapons Support is considering a future solicitation and award of an Indefinite Quantity Contract/Long-Term Contract potentially lasting 3 to 5 years; active NSNs would be priced at initial award, while inactive NSNs would be included but unpriced until demand materializes and price is determined fair and reasonable. Interested sources able to manufacture one or more listed items should provide company name, location, and points of contact directly to Kristina.Wolf@dla.mil, and if commercial, documentation supporting commerciality.
