PACKING ASSEMBLY

DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA AVIATION.DLA AVIATION PHILADELPHIA.DLA AVIATION AT PHILADELPHIA, PA · Response deadline: Mon, 09 Nov 2026

What the government is buying

This is a packing assembly procurement from DLA Aviation at Philadelphia, PA. NAICS code 339991 covers "Gasket, Packing, and Sealing Device Manufacturing," which includes mechanical packing and sealing materials used in aircraft and other defense systems. Packing assemblies are critical components that prevent leaks around moving parts like rods, pistons, and rotating shafts in hydraulic, fuel, and pneumatic systems common to military aviation platforms.

Given the classification code 5330 (which corresponds to packing and gasket materials in federal supply classification), this likely involves specialized fiber, rubber, or composite packing materials manufactured to military specifications for durability under extreme temperatures, pressures, and chemical exposures. These components must meet stringent aerospace standards for reliability and safety.

Key facts

Who can bid

This solicitation is full and open competition with no small business set-aside. Any responsible offeror—including large manufacturers, nontraditional defense contractors, and small businesses—may submit a bid.

Small businesses in NAICS 339991 remain eligible to compete. DLA's Supplier Qualification Program typically requires registration in the Procurement Integrated Enterprise Environment (PIEE) and compliance with quality standards such as AS9100 or ISO 9001 for aviation products. Prospective bidders should verify their SAM.gov registration is active and their CAGE code is current.

Manufacturers with experience supplying to original equipment manufacturers (OEMs) in aerospace, automotive sealing, or industrial fluid systems may find this opportunity accessible. Companies holding existing defense contracts for similar FSC 5330 items may have advantage in meeting technical and first-article inspection requirements.

How to put together a competitive bid

Understand the technical requirements thoroughly. Packing assemblies for DLA Aviation typically require conformance to military specifications (such as MIL-P- or MIL-DTL standards), specific material compositions, dimensional tolerances, and performance testing. See the solicitation for the exact specification and any approved sources or qualification requirements.

Evaluate manufacturing capacity. Determine whether you will produce in-house or subcontract specialized elements. DLA may require first article testing or source inspection; factor these costs and lead times into your pricing.

Assess your supply chain. Raw materials for aerospace-grade packing—such as PTFE, graphite, aramid fibers, or specialty elastomers—have seen price volatility and availability constraints. Secure Quotes from qualified suppliers before finalizing your bid.

Review past procurement data. Search SAM.gov for historical awards under FSC 5330 by DLA Aviation Philadelphia to understand pricing benchmarks and incumbent performance. This open competition means no preference for prior contractors, but understanding market rates strengthens your position.

Prepare a complete proposal. DLA solicitations typically require technical proposals, past performance references, and complete pricing. Missing certifications or representations can disqualify otherwise competitive offers.
