Seal Master Corp

Seal Master Corp, a small business manufacturer based in Kent, Ohio, delivers custom-engineered, fabric-reinforced inflatable seals and nonmetallic sealing components to the Department of Defense as a prime contractor across a diverse portfolio of indefinite delivery contracts with the Defense Logistics Agency. The company operates primarily in full-and-open competition without set-aside designations on most task orders, though several underlying IDVs carry Total Small Business set-aside status; across its recent award footprint, about 72% of awards are distributed among three DLA divisions (Land and Maritime, Aviation, and Troop Support Hardware), with the remainder spanning naval and air force supply commands.

Seal Master's capability portfolio centers on precision-manufactured seals and seal assemblies for military vehicles, aircraft, vessels, and equipment. Representative work includes a $216,148.80 delivery order from DLA Land and Maritime for seal assemblies (awarded September 2024), a $463,372 purchase order from DLA Aviation for inflatable seals to DLA Distribution San Diego (June 2025), and a $306,491.61 purchase order from DLA Land and Maritime for seal assemblies under a Total Small Business set-aside (January 2022). The company also delivered a $40,316.60 replacement seal for NASA's Shared Services Center (March 2023), demonstrating occasional work outside DoD.

Customer concentration is heavily DLA-dominated. DLA Land and Maritime (64 awards, $7 million combined potential value) and DLA Aviation (50 awards, $7.2 million) together account for 72% of awards by count and 98% of combined potential value across the portfolio. DLA Troop Support Hardware (32 awards, $3.2 million), the Department of the Navy Naval Supply Systems Command (10 awards, $2.9 million), and the Department of the Air Force (22 awards, $37 thousand) comprise the remaining tracked customer base. The top five customers cover 98% of combined potential value. Seal Master holds single-award indefinite delivery contracts directly with DLA Land and Maritime: a $2,906,115.68 IDC for seal assemblies through August 2028 (awarded August 2023, no set-aside), a $250,000 IDC for inflatable seals (June 2025, Total Small Business set-aside), and a $250,000 IDC for windshield seals (December 2024, Total Small Business set-aside). Task orders flow primarily through these vehicles; the largest parent vehicle tracked in the portfolio is IDC SPE7LX23D0105 with 23 task orders valued at $1.3 million combined, followed by SPE4A720D0098 (9 task orders, $465 thousand) and SPE4A715D0291 (8 task orders, $362 thousand).

Activity has grown steadily — 12 awards in 2022 climbing to 25 in 2024 — before moderating to 19 in 2025 and 2 year-to-date in 2026. Three awards totaling $563 thousand face completion within the next twenty-four months, presenting modest recompete exposure. The vendor's recent award footprint spans 247 total prime and sub awards with $20.9 million in combined potential value; 86% of that value is obligated. Seal Master also subcontracts on specialized defense projects: a $X inflatable hatch seal sub to Beyond New Horizons LLC (April 2025) for Test Operations and Sustainment work, and a subcontract to Electric Boat Corporation (June 2023). The vendor's core NAICS footprint is Gasket, Packing, and Sealing Device Manufacturing (110 awards), with secondary exposure in Other Aircraft Parts and Auxiliary Equipment Manufacturing (48 awards). Seal Master has been registered in SAM.gov since 2001 and holds no identified parent contract vehicles such as GWACs or governmentwide BPAs; its federal work flows entirely through direct DLA indefinite delivery contracts and spot purchases.
