DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA LAND.DLA LAND COLUMBUS.DLA WEAPONS SUPPORT · Response deadline: Tue, 27 Oct 2026
What the government is buying
The Defense Logistics Agency (DLA)—specifically DLA Land, Weapons Support—is seeking to procure nonmetallic round seals. This is a routine supply procurement through DLA's standard catalog buying process for maintenance, repair, and operations (MRO) items that support military weapon systems and equipment.
Nonmetallic round seals are common consumable items used in fluid sealing applications where metal seals would be unsuitable due to chemical compatibility, temperature, or flexibility requirements. These parts typically serve as gaskets, O-rings, or specialized sealing components for military vehicles, weapons platforms, and support equipment. DLA Land manages the supply chain for ground-weapon systems and related materiel for all military branches.
As a "Combined Synopsis/Solicitation," this notice serves as both the announcement of the requirement and the formal solicitation document—vendors can respond directly to this posting without waiting for a separate solicitation release.

Who can bid
This procurement is unrestricted—no small-business set-aside applies. Any responsible offeror, including large businesses, small businesses, and nontraditional defense contractors, may submit a bid. Small-business competition will be against all other qualified sources.
Under NAICS 339991 (Gasket, Packing, and Sealing Device Manufacturing), the standard Small Business Administration size threshold applies. Manufacturers and suppliers of rubber, plastic, composite, or other nonmetallic sealing products should evaluate their product lines against the specific seal characteristics required. Distributors may also participate if they can meet DLA's sourcing and qualification requirements.
DLA Land typically awards these types of requirements to suppliers already holding qualifying contracts or capable of meeting technical and quality specifications for military-grade components. First-time DLA vendors should verify their SAM.gov registration is active and that they understand DLA's supplier requirements.
How to put together a competitive bid
Understand DLA's buying mechanism. This is likely a catalog/part-number buy against DLA's Technical Data or a manufacturer-specific National Stock Number (NSN). Verify whether your firm can supply the exact item or an approved alternate.
Compete on price and delivery. With no set-aside restricting competition, cost and schedule typically drive award decisions for standard hardware items. Review your pricing against historical DLA purchases for similar seals if available.
Confirm technical compliance. Nonmetallic seals for defense applications often require material certifications, conformance to military specifications (such as MIL-SPEC rubber compounds), and lot-traceability documentation. See the solicitation for exact material, dimensional, and performance requirements.
Check packaging and marking requirements. DLA has strict military packaging standards (MIL-STD-2073) that can affect your delivered price.
Evaluate your supply chain. Can you reliably source the base material and manufacture or deliver within DLA's required timeframe? Lead times for specialty elastomers can be lengthy.
Consider DLA's Continuous Support terms. Many DLA procurements include options for additional quantities or follow-on years; factor this into your pricing strategy if applicable.
