The Army Contracting Command – Redstone Arsenal, supporting Letterkenny Munitions Center, is conducting market research to identify sources capable of supplying military-grade sealing compounds PR 1664D, PR-2414, and PR-2414T. The anticipated acquisition is a single firm-fixed-price contract with a 5-year duration, requiring about 50 kits of each part number annually (250 kits per part over five years). These compounds are based on PPG Aerospace specifications, and because the Government lacks complete competitive technical data packages, non-OEM alternatives must demonstrate exact fit, form, function, chemical compatibility, and rain erosion/RAM performance equivalence. Delivery will be to Letterkenny Munitions Center, Building 3315, Chambersburg, PA 17201, with receiving hours 0700–1500 EST Monday through Thursday and shipments requiring COA/COC documentation and depot safety/security compliance. Interested businesses should provide a capability statement covering OEM/authorized-distributor status, quality certifications, past performance, manufacturing and shelf-life capacity, and non-binding ROM pricing.
