Browse NSN Parts by Manufacturer
The manufacturer directory below provides an organized way to locate NSN parts manufacturers and associated components. Manufacturers are arranged alphabetically, including numeric entries and manufacturers from A through Z, allowing buyers to quickly narrow their search when the manufacturer is already known.
Select a manufacturer to access its available part-number catalog and associated NSN components.
Manufacturer-based searching can be particularly useful when your procurement documentation provides a manufacturer name but does not include a complete NSN. It can also help when you have an NSN or manufacturer part number and need to investigate the corresponding manufacturer information.
The directory can support searches involving:
NSN numbers
Manufacturer part numbers
Manufacturer names
CAGE Codes
NIINs
Federal Supply Class (FSC)
Component descriptions
Aerospace and defense part references
Existing procurement records
This approach helps reduce unnecessary searching across unrelated parts when a manufacturer is already identified in your requirement.
NSN Manufacturer Part Number Sourcing
A manufacturer part number (MPN) identifies a component according to the manufacturer's numbering system, while an NSN (National Stock Number) provides a standardized identification for an item of supply.
These identifiers can be used together when sourcing aerospace and defense components. A procurement requirement may begin with an MPN and require the corresponding NSN, or it may begin with an NSN and require manufacturer-specific part information.
A typical identification path may look like:
Manufacturer → Manufacturer Part Number → NSN → CAGE Code → RFQ
The reverse can also apply:
NSN → Manufacturer → Part Number → Procurement Request
Providing multiple identifiers gives the sourcing team more information to work with and can help distinguish the required item from similar components.
The manufacturer catalog is therefore useful for buyers who need to move between manufacturer information and standardized NSN identification during procurement.
NSN, Manufacturer Part Number & CAGE Code Identification
Accurate part identification is essential when sourcing aviation parts, aerospace components, military hardware, and defense supply items. Similar descriptions or closely related part numbers can represent different configurations, specifications, or supply records.
Each identifier provides a different piece of procurement information:
NSN: Provides the standardized identification used for an item of supply.
NIIN: Represents the identifying portion of an NSN.
Manufacturer Part Number: Provides the manufacturer's reference for a particular component.
CAGE Code: Identifies a commercial or government entity associated with a supply record.
FSC: Places the item within its Federal Supply Classification.
Part Description: Adds descriptive information that can assist with component identification.
When several of these references are available, they can be submitted together to create a more precise sourcing requirement.
What Is an NSN Manufacturer?
An NSN manufacturer is a manufacturer or identified supply entity associated with an item represented within the National Stock Number system. Manufacturer information can be used alongside an NSN, manufacturer part number, and CAGE Code to help identify and source a required component.
For procurement teams, manufacturer information is especially useful when a requirement originates from an existing part number, technical document, maintenance record, or established supply reference.
Aerospace & Defense Parts by Manufacturer
Manufacturer-based sourcing is particularly relevant to procurement requirements involving aerospace parts, aviation components, military parts, defense equipment, and electronic or mechanical components.
Instead of searching an unrestricted catalog, buyers can begin with a known manufacturer and move into the corresponding part listings.
This can be useful for sourcing:
Aircraft components
Aerospace hardware
Military components
Defense parts
Electrical and electronic components
Avionics-related parts
Bearings and mechanical components
Seals and gaskets
Fittings and connectors
Fasteners and hardware
Hydraulic and pneumatic components
Communication equipment
Ground support equipment
Other NSN-listed supply items
The exact availability and manufacturer association depend on the individual part record. For procurement purposes, the most effective approach is to provide the exact NSN or manufacturer part number whenever it is available.
NSN Parts for MRO & Defense Procurement
Maintenance, repair, and overhaul operations often require components that must be identified precisely before procurement. A buyer may receive a part number from maintenance documentation, an equipment record, a technical drawing, or an existing inventory system rather than a complete NSN.
The manufacturer catalog provides another route for researching those requirements.
For MRO procurement teams, manufacturer-based searching can help when:
The manufacturer is known but the NSN is not.
The manufacturer part number is available.
An NSN needs to be associated with manufacturer information.
Multiple parts from one manufacturer are required.
A legacy component must be investigated.
A replacement or difficult-to-source part requires additional identification.
This makes manufacturer information a practical part of the broader NSN sourcing process rather than simply a directory reference.
Hard-to-Find & Obsolete NSN Parts
Some aerospace and defense procurement requirements involve obsolete, discontinued, legacy, or hard-to-find NSN parts. These components may remain necessary because the aircraft, equipment, vehicle, or support platform they belong to is still operational.
A conventional commercial product search may not provide a useful result for these requirements. Manufacturer information, historical part numbers, NSNs, CAGE Codes, and other identification references can become more valuable when researching legacy components.
When submitting an RFQ for a difficult-to-source item, provide every identifier available, including:
NSN
Manufacturer part number
Manufacturer name
CAGE Code
Required quantity
Part condition
Required delivery timeframe
Certification or documentation requirements
Additional technical references
Even when you do not have every identifier, you can submit the information available for the requirement. A detailed RFQ gives the sourcing process a stronger starting point.
Search NSN Parts by Manufacturer or Part Number
Different procurement requirements call for different search approaches.
If you know the manufacturer, start with the manufacturer directory and select the applicable company to review associated part listings.
If you know the manufacturer part number, use that reference when requesting the component and include the manufacturer name when available.
If you know the NSN, provide the complete NSN because it offers a more precise item reference.
If you know the CAGE Code, include it with the manufacturer and part number information when submitting your requirement.
This gives buyers multiple ways to approach the same sourcing requirement:
Known Manufacturer: Manufacturer Directory → Manufacturer Catalog → Associated Parts → RFQ
Known Part Number: Part Number → Manufacturer Information → NSN Reference → RFQ
Known NSN: NSN → Associated Manufacturer → Part Information → RFQ
The appropriate route depends on the information available in your procurement documentation.
NSN Manufacturer Catalog for Procurement Teams
The manufacturer catalog is designed for buyers who need more than a general product search. It provides a structured way to investigate manufacturer-specific NSN parts and move toward a procurement request.
This can support:
Aerospace procurement
Defense procurement
Aviation MRO
Government supply requirements
Military logistics
Replacement-part sourcing
Legacy equipment support
Industrial NSN procurement
For buyers handling multiple requirements, manufacturer-based searching can also help organize research around a known supplier or manufacturer rather than treating every part as an isolated search.
When the exact part is identified, the next step is to submit an RFQ with the available procurement information.
Request a Quote for NSN Parts
Once you have identified the required manufacturer or component, submit an NSN parts RFQ with the information available for your requirement.
For the most precise sourcing request, include:
NSN / National Stock Number
Manufacturer part number
Manufacturer name
CAGE Code, if available
Quantity required
Part condition, when applicable
Required delivery date
Certification or documentation requirements
Any additional procurement notes
You do not necessarily need every identifier to begin a sourcing request. If your documentation only provides a manufacturer, part number, or NSN, submit those details and include any additional information that can help identify the required component.
For multiple-part requirements, provide the complete list of NSNs, part numbers, manufacturers, and quantities so the requirement can be evaluated as a whole.
Why Provide Multiple Part Identifiers?
Using more than one identifier can improve the clarity of an RFQ. An NSN establishes the standardized supply reference, while the manufacturer part number and manufacturer information provide additional context for the requested component.
A CAGE Code can provide another entity-level reference, while quantity and delivery requirements define the actual procurement need.
The more precise the information, the easier it is to understand exactly what the buyer is requesting.
