This contract is for the procurement of two check valve parts kits, identified by NSN 4820007582943 and Emerson Automation Solutions part numbers S90066, 300450, and 300410. Each kit must include one clapper assembly, one cover o-ring, and one clapper seal, with material MIL-B-24480 being acceptable. This is designated as a critical application item. The delivery is set for FOB Origin with a required delivery date of July 23, 2027, and a delivery window of 161 days. The agreement mandates strict adherence to DLA packaging requirements and MIL-STD-2073-1 for kit preservation. It explicitly prohibits the use of Class I ozone-depleting chemicals and the intentional addition of mercury or mercury-containing compounds, except where functionally required by specific systems. Because the manufacturing of this item may require specialized casting or forging tooling that the government may not possess, contractors are advised to utilize the DLA Casting and Forging Assistance Request process for sourcing.
