The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting quotes for the procurement of five oxygen regulators (NSN: 015303498, PN: F241-2400-11). The items require government source approval prior to award, and interested vendors must submit a proposal along with the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online. These regulators are critical for aircraft operations, ensuring the safety and functionality of air conditioning, heating, and pressurizing systems. Proposals must be submitted via email to Christopher Campello by the specified due date, and any offers lacking the required source approval information will not be considered for award.
