This document is a parts list containing nomenclature and National Stock Numbers (NSN) for components used in a complex mechanical and electrical assembly system. The list identifies 33 distinct parts with their corresponding part numbers and NSNs where applicable. The components span multiple functional categories including pressure sensing (Pressure Sensor -14.5-0psi, NSN 6685-01-671-0082), fluid control (Auto Ball Valves, Relief Valve, Mixing Valve Assembly, Vacuum Pump), electrical distribution (Contactor 150A, Fuses, Fuse Holder), power conversion (DC/DC Converter, Power Supply Assembly, Signal Converter), and structural elements (EMI Panels, Radiator/CAC Assembly, LC Output Filter). Hardware fasteners include 1/4-20 studs and nuts, while miscellaneous components encompass connectors, switches, potentiometers, and Viton O-rings in various sizes.

Approximately 64% of the listed parts have assigned NSNs, indicating standardized federal procurement items, while the remaining components lack NSN assignments. The parts appear to support an integrated system requiring both mechanical pressurization and vacuum capabilities alongside sophisticated electrical control and monitoring functions. This parts list likely serves as a bill of materials for a solicitation, contract specification, or technical requirement document for the procurement or manufacture of a specialized system.
