O-rings for aviation maintenance and overhaul sourcing. Search by manufacturer part number or NSN. Listings are PartsPerk-owned observations for review — not live inventory or airworthiness approval. Use the manufacturer part number or NSN from the work card before guessing a family. Path Hardware → O-rings is a catalog placement signal, not interchange, stock, or price. Open a listed identity for image, specs, and RFQ context — or search the exact PN from this leaf.
Why this leaf exists
Unique context for O-rings, not a thin copy of the parent.
This leaf keeps O-rings-specific guidance so crawlers and buyers are not served duplicated department prose. Confirm finish, dash, pack, and applicability on the part page. Request sourcing carries quantity and document needs; this page does not invent availability.

Frequently asked questions
How do I choose an O-ring series?
Match the specification and dash size from the maintenance data (for example MS29513 vs MS29561). Compound and fluid compatibility are required on the RFQ.
How do I pick the correct part?
Start with the manufacturer part number from the illustrated parts catalog or maintenance manual. If an NSN is listed, search that next. Confirm finish, dash number, and engine or airframe applicability before opening an RFQ.
Are these listings in stock or certified?
No. Category pages show PartsPerk-owned observations for sourcing review. Stock, price, trace, and airworthiness stay off the page until a separate publication review.
Can fleet and shop orders be reviewed together?
Yes. Submit quantity, required documents, and need-by date through the sourcing desk. Volume review is human — these pages do not auto-discount.
PartsPerk catalog pages show PartsPerk-owned observations only. They are not live stock, not certification, and not OEM affiliation. Exact PN/NSN identity is for sourcing review; publication and sellability require separate approval.
