PACKING, PREFORMED
DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSUP.NAVSUP WEAPON SYSTEMS SUPPORT.NAVSUP WSS MECHANICSBURG.NAVSUP WEAPON SYSTEMS SUPPORT MECH · Response deadline: Thu, 05 Nov 2026
What the government is buying
NAVSUP Weapon Systems Support Mechanicsburg is procuring preformed packing materials for defense logistics support. Preformed packing—commonly gaskets, O-rings, seals, and shaped compression elements—serves critical functions in naval weapon systems and support equipment by preventing leakage, maintaining pressure integrity, and protecting components from environmental contamination.
The NAICS code 336310 corresponds to "Motor Vehicle Gasoline Engine and Engine Parts Manufacturing," though this classification is sometimes applied more broadly to precision-manufactured sealing components and engine-related parts in federal procurement. The classification code 5331 further specifies packing and gasket materials. This type of procurement typically supports maintenance, repair, and overhaul operations across Navy weapon systems, where exact-fit preformed packing reduces installation time and improves reliability compared to field-cut alternatives.

Who can bid
This solicitation is open to all responsible sources; no small-business set-aside applies. Any manufacturer or distributor capable of meeting the technical, quality assurance, and delivery requirements may compete. Given the NAICS classification, typical bidders include:
- Manufacturers of rubber, polymer, composite, or metal-reinforced packing and sealing products
- Specialty distributors holding authorized dealer relationships with qualified manufacturers
- Value-added resellers capable of custom fabrication, kitting, or military-specification compliance testing
Bidders should verify their SAM.gov registration is active and complete, with current Representations and Certifications. Because this supports weapon systems, all offerors must meet applicable defense contractor requirements including DFARS clauses, which may include source validation, traceability documentation, and counterfeit parts prevention protocols.
How to put together a competitive bid
For preformed packing procurement, consider these practical steps:
Technical compliance: Carefully review material specifications—likely including military standards such as MIL-PRF or AS specifications for elastomer compounds, temperature ratings, and compression set requirements. Preformed packing demands dimensional precision; verify your manufacturing process can hold stated tolerances.
Quality systems: NAVSUP WSS typically requires AS9100 or ISO 9001 certification for aerospace and defense components. If you are a distributor rather than manufacturer, secure a current manufacturer authorization letter and flow down all quality requirements.
Past performance: Prepare relevant citations for similar defense packing or seal contracts, especially those involving MIL-spec compliance, lot traceability, or Defense Logistics Agency transactions.
Pricing strategy: Full-and-open competition means experienced large manufacturers may bid. Small businesses should emphasize flexibility, reduced minimum order quantities, or value-added services such as consolidated kitting for specific end-items. Analyze historical prices through FPDS or SAM.gov contract data if available.
Delivery and packaging: Military packaging requirements (MIL-STD-2073) often apply. Factor in preservation, unitization, and marking costs.
