43--SEAL ASSEMBLY,SHAFT,SP

DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA MARITIME.DLA MARITIME COLUMBUS.DLA WEAPONS SUPPORT · Response deadline: Mon, 26 Oct 2026

What the government is buying

DLA Maritime is procuring seal assembly components for shaft applications—mechanical seals used in rotating equipment on naval vessels and marine systems. These parts fall under the broader category of fluid power equipment and related manufacturing (NAICS 333996). Seal assemblies for shafts are critical maintenance items in ship propulsion systems, pump systems, and other rotating machinery where preventing leakage around a rotating shaft is essential.

This is a DLA Weapons Support acquisition through the Maritime Columbus office, meaning the procurement supports weapons systems and their associated marine platforms. The specific item designation "SEAL ASSEMBLY,SHAFT,SP" suggests a specialized or specific-application seal rather than a generic commercial component, though see the solicitation for exact technical specifications, applicable military specifications, and qualification requirements.

Key facts

Who can bid

This solicitation is full and open competition with no set-aside program specified, meaning all responsible sources may submit offers regardless of business size or socioeconomic status. However, given the NAICS code 333996 and typical DLA Maritime requirements, prospective bidders should expect:

• Manufacturers with demonstrated capability to produce or supply precision mechanical seals to military specifications
• Small businesses in the fluid power or sealing technology sector, provided they can meet technical and quality requirements
• Potential for small business participation, though without a set-aside, large businesses compete on equal footing

Firms should verify their SAM.gov registration is active and that they hold any required NATO Commercial and Government Entity (NCAGE) codes or contracts for DLA supply. Prior experience with defense supply chains, MIL-STD quality systems, and shipboard equipment is advantageous.

How to put together a competitive bid

For mechanical seal assemblies in DLA maritime applications, focus on these elements:

Technical compliance: Obtain and review all referenced military specifications (likely including dimensional, material, and performance standards). Seal assemblies for shaft applications on naval vessels must withstand corrosive marine environments, pressure differentials, and extended operating cycles. See the solicitation for exact specification sheets.

Traceability and quality certification: DLA typically requires certified material test reports, source inspection, and adherence to ISO 9001 or AS9100 quality systems. Document your manufacturing process controls and testing capabilities.

Past performance: Highlight contracts for similar seal assemblies, especially to DLA, Navy, or Coast Guard. Include delivery performance data and any quality awards.

Pricing strategy: Research historical pricing for comparable NSN items through DLA's public pricing tools. Factor in certification costs, potential first article testing requirements, and packaging for military shipment (likely MIL-STD-2073).

Packaging and marking: DLA Maritime has strict packaging requirements for corrosion-critical items. Include these costs in your proposal.

Small business considerations: Without a set-aside, emphasize any Small Business Innovation Research (SBIR) technology, manufacturing competitiveness, or subcontracting partnerships that strengthen your offer.
