Ace Trading Nipple Parts and NSN Lookup

How to Verify a Part Before Quoting

A part number alone does not always identify one item, because the same number can be issued by more than one manufacturer. Pair every number with its manufacturer, and with the CAGE code where one is available, before comparing listings.

Government and aerospace requirements add a second identifier. An NSN has 13 digits: a 4-digit supply class followed by a 9-digit NIIN, and the first two NIIN digits show the codification bureau (00 and 01 are the United States).

Take 10819 and check it in this order:

• Prefix and body: confirm the series and the item within it in the manufacturer’s catalogue. A one-digit change normally means a different size or rating.

• Suffix: trailing characters often mark a revision, finish, material or pack size. The same body with a different ending is a different variant until the datasheet says otherwise.

• NSN: match all 13 digits. The first four give the supply class and the last nine identify the item.

• Dimensions: inch and metric values, tolerances, and thread or bore specifications must match the drawing separately from the number.

Sourcing Checklist for B2B Buyers

Quotes are faster and more accurate when the request carries complete details:

• Part number, NSN and manufacturer or CAGE code

• Required quantity and pack size

• Condition requirement, such as new, new surplus or overhauled

• Documentation needs, such as certificates of conformance or traceability records

• Delivery location, need-by date and any acceptable alternate part numbers

Browsing by Category and Subcategory

If the exact number is unknown, start from the function. Parts in this category are grouped by subcategory, such as Pipes Valves And Fittings, so you can narrow to a component family and then compare descriptions, sizes and materials in the parts catalog.
Use the table and the verification steps to shortlist items, then confirm every specification against your own drawing or datasheet. To compare other sources, return to the manufacturer directory.
