About Marco Rubber & Plastics, LLC
Marco Rubber & Plastics, LLC, a small business based in Seabrook, New Hampshire, manufactures and supplies high-precision sealing components—O-rings, gaskets, EPDM sponge tubing, and related elastomer products—to the U.S. Navy as a prime contractor under total small business set-asides, with 99% of its recent federal footprint concentrated in prime awards and minimal sub activity.
The company operates as a for-profit limited liability partnership with a subsidiary, Ipotec LLC, and competes predominantly under small business set-asides across its Navy work. Marco Rubber's capability portfolio centers on precision gasket and sealing device manufacturing (NAICS 326290, Gasket, Packing, and Sealing Device Manufacturing), with secondary exposure in adhesive manufacturing and synthetic rubber fabrication. Representative recent prime work includes a $60,577.50 total small business set-aside purchase order from Naval Sea Systems Command (NAVSEA) for O-rings for Durax TI equipment awarded March 27, 2026, a $64,700 total small business set-aside for O-rings for Dura-X tile gasket equipment awarded February 7, 2025, and a $58,820 total small business set-aside for O-rings for Durax TI equipment awarded April 27, 2024. All three contracts specify firm fixed-price delivery terms with performance at the company's Seabrook facility or Portsmouth, Virginia location.
Customer concentration is extreme: NAVSEA anchors 56 of 76 recent awards (92% of the prime footprint) worth $767 thousand combined potential value, with the Department of the Navy Naval Supply Systems Command placing 7 awards and representing the second-largest customer by award count but not appearing in the potential-value top-five. The vendor serves nine distinct federal agencies, but the top five agencies account for all measurable dollars. Place of performance spans Seabrook, New Hampshire (primary manufacturing), Portsmouth, Virginia, and shipboard and shore installations including Pearl Harbor, Hawaii for Navy equipment support.
Recent activity is episodic—one award in 2021, four in 2023, two in 2024, five in 2025, and two in 2026 year-to-date—reflecting the transactional, purchase-order-driven nature of Navy component procurement. Combined potential value across all 76 awards in the source data totals $793 thousand, but obligated dollars across all awards reach $1.2 million (154% of stated potential value), indicating that actual task orders and deliveries have exceeded ceiling values. The vendor maintains a single identified parent vehicle: Indefinite Delivery Contract N0010285C4156, which carried one task order. Sub activity is negligible—Marco Rubber took one subcontract award from Dynetics, Inc. on April 9, 2026 for procurement goods and services in support of a laser air monitoring system contract running through August 27, 2027. The vendor's federal contracting history dates to at least 2000 and demonstrates consistent low-dollar, high-frequency delivery of mission-critical sealing components to Navy shipbuilding, maintenance, and operational readiness operations.
