Magnetic Seal LLC

Magnetic Seal LLC, a Warren, Rhode Island-based precision aerospace components manufacturer, supplies seals, O-rings, magnetic seal assemblies, and related sealed enclosures to the Defense Logistics Agency as a prime contractor (97% of awards) competing in full-and-open procurements with no set-aside designations. The company is a child entity of Ducommun Labarge Technologies, Inc., a for-profit manufacturer.

Magnetic Seal's customer base is heavily concentrated within the Defense Logistics Agency ecosystem. The top five customers by award count account for 68% of recent awards, dominated by DLA Land and Maritime (131 awards, $6.4 million combined potential value) and DLA Aviation (41 awards, $2.8 million). The Department of the Air Force, Department of the Army, and DLA Troop Support Construction and Equipment round out the active set. By dollar value, DLA Land and Maritime and DLA Aviation anchor 69% of combined potential value, with the broader DLA organization accounting for the vast majority of Magnetic Seal's federal revenue stream. Representative prime work includes a $1.45 million firm fixed-price purchase order from DLA Land and Maritime (March 18, 2025) for 716 plain encased seals (NSN 5330-01-274-4251), a $793,934 purchase order from DLA Aviation (August 26, 2025) for 300 units of seal replacement parts kits, and a $739,999 purchase order from DLA Aviation (October 27, 2025) for metallic non-aircraft seals.

Magnetic Seal holds three single-award Indefinite Delivery Contracts with DLA Land and Maritime: a $350,000 contract awarded January 15, 2026, for plain seals (effective through January 15, 2027); a $250,000 contract awarded September 12, 2025, for O-rings (effective through September 12, 2026); and a $250,000 contract awarded May 1, 2025, for plain encased seals (expired May 10, 2025). Work under these vehicles is classified under NAICS 339991 (Gasket, Packing, and Sealing Device Manufacturing) and PSC 53 (Hardware and Abrasives). Magnetic Seal's broader award portfolio spans 180 awards under the primary NAICS 339991, with secondary activity in pump manufacturing (48 awards) and aircraft parts manufacturing (47 awards). Delivery is consistently performed at Magnetic Seal's Warren, Rhode Island facility, with items distributed to DLA depots across continental United States and overseas consolidation points.

Activity shows modest recent volume — twelve awards in 2024, twenty-nine in 2025, and eleven through mid-2026 — with eleven awards (combined potential value $1.9 million) completing within the next twenty-four months and facing recompete exposure. The top parent vehicles are Indefinite Delivery Contract SPM7MX09D9014 (40 task orders, $735 thousand combined potential value), SPM48004D0751 (16 task orders, $294 thousand), and Basic Ordering Agreement F0960392G0054 (14 task orders).

In its subcontracting capacity, Magnetic Seal supplies aerospace components to Boeing, Rolls-Royce, Sikorsky Aircraft, Lockheed Martin, and Meggitt Defense Systems. Named sub work includes Apache helicopter airframe interiors and post-production support services under Boeing (multiple awards from June through May 2025), a compressor rotary magnetic seal shaft assembly under Meggitt Defense Systems (January 2025), and aircraft engine and gearbox assemblies under Rolls-Royce and Sikorsky (January and April 2024).

Magnetic Seal's footprint across the federal supply chain is characterized by high-frequency, modest-dollar-value purchase orders and delivery orders for source-controlled, military-specification sealing components distributed through DLA depots. The vendor competes exclusively in full-and-open procurement, with no history of set-aside participation, positioning it as a cost-competitive supplier within the defense industrial base's sealed-component ecosystem rather than a niche or sheltered-market player.
