The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is seeking proposals for the procurement of 40 units of a flight-critical brake valve, specifically NSN 7R-2530-014183264-V2, with reference number 901-380-041-107. The procurement requires that the item be sourced from approved suppliers as specified by the Government, due to the lack of available technical data for alternative sources, which necessitates Government source approval prior to contract award. This valve is essential for vehicular brake systems, and interested vendors must submit comprehensive documentation for source approval along with their proposals, as offers lacking the required data will not be considered. For further inquiries, Rachel Raucheisen can be contacted at (215) 737-7063 or via email at RACHEL.RAUCHEISEN@DLA.MIL.
