About the company
Kirkhill, Inc., a wholly-owned subsidiary of TransDigm Group Incorporated, manufactures specialty nonmetallic seals, elastomeric gaskets, and aerospace defense components as a prime contractor (88% of recent awards) on full-and-open federal procurements with no socioeconomic set-asides, competing on technical capability and delivery performance. The company is based in Brea, California, and operates under primary NAICS 339991 (Gasket, Packing, and Sealing Device Manufacturing) with a 100+ year manufacturing history in high-performance elastomer products for military and commercial aviation.
Kirkhill's customer base shows extreme concentration in the Defense Logistics Agency. DLA Land and Maritime and DLA Aviation together represent 413 of 470 recent awards (88% of award count) and $19.8 million of the $20 million combined potential value (99%). Within that concentration, DLA Land and Maritime leads with 254 awards valued at $11.4 million, while DLA Aviation accounts for 159 awards at $8.4 million. The remaining customers—NASA Marshall Space Flight Center (24 awards), DLA Troop Support Construction and Equipment (13 awards), and the Navy (7 awards)—account for only 3% of potential value. Kirkhill's award activity has grown steadily: 81 awards in 2022, 85 in 2023, 119 in 2024, and 107 in 2025, with 48 awards through August 2026. Nine awards totaling $341 thousand face completion within the next twenty-four months.
Kirkhill's recent work consists entirely of purchase orders and delivery orders placed against single-award indefinite delivery contracts with DLA. The vendor holds five active IDCs with DLA Land and Maritime, each ceiling-valued between $250,000 and $350,000 through 2027, procuring plain seals, structural seals, nonmetallic seals, aircraft component boots, and related elastomeric items under firm fixed-price commercial-item terms. Representative recent prime awards include a $349,997 purchase order for 823 nonmetallic seal units (March 2026), a $188,160 delivery order for aircraft air conditioning duct assemblies (December 2025), a $170,957 purchase order for aircraft component boots (February 2026), and a $156,449 purchase order for aircraft air diffusers (January 2025), all with DLA Aviation or DLA Land and Maritime and all performed in Brea, California.
In its subcontractor role, Kirkhill supplies elastomeric components and aircraft seals to The Boeing Company under programs including the C-17 Globemaster III sustainment, F-15EX aircraft, P-8A maritime patrol aircraft, and CH-47F cargo helicopter long-lead procurement. The company also subcontracts to ATK Launch Systems LLC on the Space Launch System booster production contract for synthetic rubber manufacturing. Boeing sub-awards dominate Kirkhill's subcontract footprint, representing the bulk of the 55 sub-awards in the recent portfolio.
Kirkhill does not compete in set-aside categories. All recent awards carry full-and-open designations with no 8(a), HUBZone, SDVOSB, or WOSB restrictions. The company's competitive position rests on source-control approvals, established supplier status within DLA's vendor base, and delivery performance on specialized, military-specification elastomeric components. The vendor's parent, TransDigm Group Incorporated, is a for-profit manufacturer of aerospace and defense goods with active federal contracting and grant award participation across multiple subsidiaries.
