DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA LAND.DLA LAND COLUMBUS.DLA LAND AND MARITIME · Response deadline: Thu, 15 Oct 2026
What the government is buying
The Defense Logistics Agency (DLA) Land and Maritime is seeking a small business to supply seals, plain—a category of mechanical sealing components used in equipment maintenance and repair. This falls under DLA's routine procurement of spare parts and supply items that support military readiness. Plain seals are typically non-spring-energized, static sealing devices made from elastomeric or polymer materials, used to prevent leakage between mating surfaces in machinery, vehicles, and industrial equipment.
The NAICS code 339991 classifies this as "Gasket, Packing, and Sealing Device Manufacturing," which includes the production of:
- Molded rubber seals and O-rings
- Mechanical seals for rotating equipment
- Compression packings and gaskets
- Other fabricated sealing products
This is standard sustainment procurement for DLA Land and Maritime, which manages the supply chain for land and maritime weapon systems. The agency's Columbus, Ohio, facility handles contracting for this class of industrial items. The specific part number, material specification, dimensions, and performance requirements for this seal see the solicitation for complete technical details.

Who can bid
This opportunity is reserved entirely for small businesses under the Small Business Set Aside — Total designation. Your business must:
- Meet the NAICS 339991 size standard: To qualify as small, you must have no more than 1,000 employees (the SBA size standard for this industry)
- Be registered in SAM.gov and current in your representations and certifications
- Appear in DSBS (Dynamic Small Business Search) if you want contracting officers to find your capabilities profile
- If you are a manufacturer, you generally must be the source that "makes" the item or performs its "substantial transformation" to count as a small business manufacturer under nonmanufacturer rule exceptions; otherwise, you may need to comply with nonmanufacturer requirements
DLA Land and Maritime frequently sources these items from small manufacturers or qualified distributors. If you do not manufacture seals yourself, review whether this solicitation qualifies for the nonmanufacturer rule or requires brand-name justification.
How to put together a competitive bid
Technical compliance: DLA supply contracts for seals typically reference military or commercial specifications (such as AMS, MIL-PRF, or ASTM standards for materials and dimensions). Request the full specification sheets through the solicitation to confirm your product meets exact material, hardness, temperature, and pressure ratings.
Pricing structure: DLA awards these types of contracts on a firm fixed-price basis with possible multi-year or option-year structures. Check whether this is a one-time buy or requirements-type contract. Review DLA's historical pricing for similar NSNs through tools like FPDS or DLA's Customer Interaction Center if you have access.
Quality certifications: Be prepared to demonstrate:
- ISO 9001 certification (common expectation)
- Material test reports or certificates of conformance
- Traceability documentation for rubber/elastomer compounds
- Shelf-life and storage condition data if applicable
Past performance: DLA evaluates past performance rigorously. If you have prior DLA or DoD seal/sealing device contracts, highlight delivery timeliness and quality acceptance rates. If new to DLA, emphasize commercial experience and any comparable federal agency work.
QTDP and expedited delivery: Confirm whether quick turnaround or stocking agreements are expected; DLA often values supply chain reliability over lowest price for sustainment items.
