This is a pre-solicitation synopsis for the repair of four specific valves for Foreign Military Sales to Finland. The work is currently considered competitive only between the OEM, Parker Hannifin Corp, and one other approved source, though all responsible parties may submit capability statements. The government intends to negotiate with the prime contractor under sole-source authority, as complete repair data and drawings are not available. Any interested contractor must be a government-approved source or submit detailed technical data per the NAVSUP WSS Source Approval Brochure to be considered. Proposals must be submitted within 45 days of this synopsis’s publication, and the location for performance is not specified.
