What the government is buying
The Defense Logistics Agency (DLA) Aviation at Philadelphia is soliciting for metallic aircraft seals. This is a supply contract for aerospace hardware that supports DLA's mission of providing logistics support to military aviation programs. Aircraft seals are critical components used in turbine engines, airframes, and other aviation systems to prevent fluid and air leakage under extreme operating conditions. Metallic seals differ from elastomeric seals in their ability to withstand higher temperatures and pressures, making them essential for hot-section engine applications and other demanding aerospace environments.
DLA Aviation serves as the primary supplier of aviation spare parts to all U.S. military services, so this requirement likely supports ongoing sustainment of military aircraft fleets. Metallic aircraft seals are typically precision-manufactured components requiring specialized alloys, tight dimensional tolerances, and compliance with rigorous aerospace quality standards.

The NAICS code 336412 corresponds to Aircraft Engine and Engine Parts Manufacturing. While this classification primarily covers engine manufacturing, it also applies to manufacturers of engine components including seals. Businesses in this NAICS may also produce non-engine aerospace components.
Who can bid
This solicitation is open competition with no small business set-aside, meaning businesses of all sizes may bid. Both large manufacturers and small businesses certified in NAICS 336412 are eligible.
Small businesses should assess whether they can meet DLA's typical requirements for this commodity area, which often include:
- Quality management system certification (commonly AS9100 or ISO 9001 for aerospace)
- Experience with military or commercial aerospace specifications
- Approved manufacturing sources or eligibility for source approval
If your business qualifies as small under the 1,500-employee size standard for NAICS 336412, you may still benefit from subcontracting opportunities with prime bidders even if direct competition with larger firms is challenging.
How to put together a competitive bid
For metallic aircraft seal competitions, focus on these elements:
Technical compliance: Verify your product meets the specific material, dimensional, and performance specifications referenced in the solicitation. DLA typically cites military specifications (MIL-SPECs) or industry standards. Obtain exact specification numbers and revision levels from the solicitation.
Past performance: Document any prior government or commercial aerospace seal contracts. DLA evaluates delivery performance and quality history through systems like the Contractor Performance Assessment Reporting System (CPARS).
Pricing strategy: Analyze historical pricing for similar National Stock Number (NSN) items through DLA's tools or Federal Procurement Data System. Metallic seals can vary significantly based on alloy content and manufacturing complexity.
Quality assurance: Confirm your facility can accommodate any required source inspection or first article testing. Some aerospace components require government or designated agency inspection before acceptance.
Packaging and marking: DLA has strict military packaging requirements that differ from commercial standards. Factor MIL-STD-2073 or applicable packaging instructions into your proposal.
