Purchasing Sphere is a leading distributor of NSN parts, aviation parts, IT hardware parts, and more. Owned and operated by ASAP Semiconductor, we have access to an unparalleled inventory of more than two billion new and obsolete aircraft parts and components. Our website offers a broad range of parametric search measures that allow customers to efficiently browse our selection of aircraft parts through a variety of filters, such as Federal Supply Group and Class, National Stock Number, CAGE Code, manufacturer, part family, part number, and more. To further ease the procurement process, we also provide a comprehensive military part cross-reference list. Additionally, as we are an AS9120B, ISO 9001:2015, and FAA 0056B accredited company, as well as the only independent distributor with a no China sourcing policy, we can ensure that each part we sell is fully traceable or comes directly from a reputable manufacturer.
