53--O-RING
DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA LAND.DLA LAND COLUMBUS.DLA WEAPONS SUPPORT · Response deadline: Thu, 12 Nov 2026
What the government is buying
The Defense Logistics Agency (DLA) is seeking to procure O-rings, a common type of mechanical seal used in fluid or gas systems. O-rings are torus-shaped elastomer gaskets designed to sit in a groove and be compressed between two parts to create a seal at the interface. They are standard components in aerospace, military, and industrial applications where preventing leaks is critical.
NAICS code 339991 covers "Gasket, Packing, and Sealing Device Manufacturing," which includes O-rings made from various elastomeric materials such as nitrile, fluorocarbon, silicone, or ethylene propylene. In DLA's supply system, these items typically fall under Federal Supply Class 5330 (Packing and Gasket Materials) or 5331 (O-Ring), though the notice uses classification code 53.
This is a Combined Synopsis/Solicitation, meaning DLA is simultaneously announcing its intent to buy and inviting offers. These notices are common for DLA's long-term contracts and stock replenishment of standard industrial items.

Who can bid
This solicitation is full and open competition with no set-aside designation, meaning all responsible sources—including small and large businesses—may submit offers. There is no preference for small business, HUBZone, 8(a), service-disabled veteran-owned, or women-owned small business concerns.
To bid, your firm must:
- Be registered in the System for Award Management (SAM.gov) with active registration through the contract performance period
- Have the applicable NAICS code (339991) in your SAM profile
- Meet any size standard requirements if claiming small business status for other purposes
- Be capable of manufacturing or supplying O-rings to DLA's technical and quality specifications
Manufacturers of sealing devices, distributors with established supply chains for mil-spec O-rings, and precision elastomer component suppliers are typical bidders for this type of DLA requirement.
How to put together a competitive bid
For an unrestricted DLA nuts-and-bolts procurement like this, price and delivery are typically the primary evaluation factors. Consider these elements:
Technical compliance: See the solicitation for the exact size, material specification (likely an SAE Aerospace Standard or military specification such as AS568, MIL-PRF-, or MS-), hardness (durometer), and temperature rating. DLA often cites specific part numbers or National Stock Numbers (NSNs). Submitting non-conforming product is a common reason for rejection.
Quality certifications: DLA supply contracts frequently require ISO 9001:2015 or AS9100 quality management system certification. See the solicitation for specific Quality Assurance Provisions and any required first article testing or source inspection.
Past performance: DLA may evaluate your record on prior government contracts for similar items, including delivery timeliness and quality acceptance rates.
Pricing strategy: Research DLA's historical pricing for comparable NSNs through tools like FPDS or DLA's Internet Bid Bond System (DIBBS) to understand market rates. Factor in material costs for specialized elastomers, which fluctuate with petrochemical markets.
Packaging and marking: DLA has strict military packaging requirements (MIL-STD-2073 or commercial equivalents). Non-compliant packaging can result in rejection at receipt.
Small business subcontracting: If you are a large business, you will need a small business subcontracting plan.
