Burke Industries (Delaware) LLC

Burke Industries (Delaware) LLC, a subsidiary of Mannington Mills Inc. operating from San Jose, California, manufactures specialized rubber compounds and sealing materials for naval shipbuilding and vessel maintenance as a prime contractor on full-and-open procurements with no set-aside designations. The company competes exclusively in unrestricted markets and holds no SBA certifications.

Burke's federal footprint is highly concentrated in a single customer and product line. The Department of the Navy Naval Sea Systems Command accounts for the overwhelming majority of recent activity, with 39 awards carrying $3.3 million in combined potential value — representing 97% of Burke's total combined potential value across all federal work. Within that NAVSEA relationship, Burke is the sole-source provider of the proprietary NXA5126 rubber compound formulation to Navy shipbuilding and maintenance programs. Recent representative prime awards include a $237,524.80 purchase order (February 2026) for rubber compound with ultimate completion March 31, 2026; a $220,995.20 purchase order (August 2025) for rubber compounds, completed November 30, 2025; and a $189,190.08 delivery order (April 2024) for the NXA5126 compound. All of Burke's NAVSEA work flows through a larger Indefinite Delivery Contract valued at $896,261.76, with individual delivery orders historically ranging from approximately $21,000 to $189,000. Burke also holds secondary relationships with the Defense Logistics Agency, the Department of Justice Bureau of Prisons, and the Department of Navy Naval Supply Systems Command, but these represent a small fraction of dollars.

Burke's primary NAICS categories are Gasket, Packing, and Sealing Device Manufacturing (117 awards) and All Other Rubber Product Manufacturing (38 awards), reflecting its core capability in specialized elastomer formulations and marine sealants. Place of performance is consistently San Jose, California. The company maintains active subcontract relationships with Goodrich Corporation, supplying sonar dome rubber windows and Type 1 USN rubber products (two sub-awards recorded November 27, 2024).

Activity has declined over the past three years — one award in 2023, five in 2024, one in 2025, and one in 2026 — reflecting Burke's narrow, sole-source niche rather than portfolio expansion. Combined dollars obligated across all awards ($36.3 million) substantially exceed combined potential value ($4.1 million), indicating that many older awards have been fully invoiced. Burke's competitive position rests on proprietary material formulations and its established sole-source status with NAVSEA, not on vehicle access or broad market reach.
