What the government is buying
The Naval Supply Systems Command (NAVSUP) Weapons Systems Support activity in Mechanicsburg is soliciting offers for DISK,RUPTURABLE — a metal engine part falling under Federal Supply Classification 4820 (Valves, Nonpowered). This is a small business unrestricted procurement, meaning any eligible entity may compete.
Rupturable disks are pressure-relief safety devices used in mechanical systems. When internal pressure exceeds a calibrated threshold, the disk bursts to release pressure and protect equipment from damage. These components are commonly found in fluid handling, propulsion, and industrial process systems aboard naval vessels and in shore-based support facilities.

Who can bid
This solicitation is unrestricted, meaning large businesses, small businesses, and non-traditional contractors all may submit offers. There is no small business or socioeconomic set-aside applied.
Eligible bidders must:
- Be registered in the System for Award Management (SAM.gov) with active status
- Hold any required North American Industry Classification System (NAICS) 332919 qualifications
- Meet any technical, quality, or security requirements specified in the full solicitation (see the solicitation)
Given the nature of defense supply work, prospective bidders should verify whether their manufacturing capabilities align with military specifications for rupturable disks, which may involve precise burst-pressure tolerances, materials traceability, and documentation standards.
How to put together a competitive bid
For metal valve and fitting manufacturing in defense supply:
Technical compliance: NAVSUP WSS typically requires conformance to military or aerospace standards. Obtain the full technical specifications from the solicitation to confirm burst-pressure ratings, materials (often corrosion-resistant alloys), dimensional tolerances, and testing protocols.
Quality systems: Be prepared to demonstrate an acceptable quality system — often ISO 9001 or AS9100 for aerospace/defense applications. The Navy may require specific source inspection or first article testing.
Past performance: If you have delivered similar items to DOD or commercial marine/industrial customers, document this thoroughly. NAVSUP WSS evaluates past performance for spares procurement.
Pricing strategy: Competitive pricing matters, but so does total evaluated price including any packaging, marking, and delivery requirements. Review Defense Logistics Agency (DLA) pricing history for comparable national stock numbers if available.
Deliveries: NAVSUP WSS spares contracts often involve multiple delivery orders over time or require rapid response for critical need. Clarify whether this is a one-time buy or requirements-type contract with estimated quantities (see the solicitation).
Special packaging/military shipment: Verify whether Military Standard 129 or 2073 packaging and labeling apply.
