What the government is buying
The Department of the Navy, through NAVSUP Weapon Systems Support in Mechanicsburg, is soliciting offers for O-rings. This is a requirements-based procurement for a mechanical sealing component commonly used in fluid systems across naval platforms and weapon systems.
O-rings are toroidal mechanical gaskets designed to sit in a groove and be compressed during assembly between two or more parts, creating a seal at the interface. In defense applications, O-rings must typically meet stringent material specifications, dimensional tolerances, and performance standards due to extreme operating conditions including pressure differentials, temperature variations, and exposure to fuels, lubricants, or corrosive environments. The classification code 5331 (Hardware and Abrasives) and NAICS 336310 (Motor Vehicle Gasoline Engine and Engine Parts Manufacturing) indicate this is categorized as a hardware/component supply item, though the actual application context for these O-rings would be detailed in the solicitation's specifications.
Potential suppliers should note that naval aviation, surface ship, and submarine applications often require O-rings manufactured to military or aerospace material specifications (such as MIL-SPEC grades) with traceability documentation, material certifications, and conformance testing—see the solicitation for exact technical requirements, quantities, and delivery schedules.

Who can bid
This is a full and open competition with no small business set-aside, meaning businesses of any size may submit offers. Both large manufacturers and small businesses may compete.
Small businesses in NAICS 336310 (with applicable size standards) may still participate and should evaluate whether they can meet any potential small business subcontracting goals the awardee might face, or whether they might participate as subcontractors to prime bidders.
Given the specialized nature of defense-grade O-rings, potential bidders should realistically assess:
- Capability to manufacture or procure material to required specifications
- Quality management systems (often AS9100 or ISO 9001 in this sector)
- Past performance references for similar defense or aerospace supply
- Capacity for documentation and traceability requirements typical of NAVSUP procurements
How to put together a competitive bid
For this type of hardware supply contract, focus your proposal on demonstrating reliability and compliance:
Technical response: Address every material specification, dimensional, and performance requirement exactly as stated. Navy supply contracts typically use pass/fail or rated criteria for technical acceptability—omit no mandatory requirements.
Quality assurance: Detail your inspection processes, lot acceptance testing capabilities, and certificate of conformance procedures. NAVSUP WSS places heavy emphasis on quality system documentation and defect-free delivery history.
Pricing: Research historical pricing for comparable NSN or specification-grade O-rings. Full and open competition means pricing against established defense suppliers; ensure your overhead structure supports competitive pricing while maintaining quality compliance costs.
Past performance: Prepare references from similar federal or commercial contracts involving elastomeric seals, gaskets, or precision hardware. NAVSUP evaluates past performance rigorously—document on-time delivery rates, quality acceptance rates, and any corrective actions taken.
Delivery and packaging: Propose realistic lead times with buffer for material certification and testing. Understand military packaging requirements (MIL-STD-2073) if applicable—see the solicitation.
