United Seal & Rubber Company, Inc.

United Seal & Rubber Company, Inc., doing business as United Seal & Rubber Co Inc., is a minority-owned, small disadvantaged, veteran-owned, and Hispanic American-owned manufacturer of elastomer and sealing components based in Atlanta, Georgia, that operates as a prime contractor (98% of recent awards) and subcontractor supplying gaskets, seals, o-rings, and specialized nonmetallic components to the Department of Defense and Defense Logistics Agency. The company competes predominantly in full-and-open procurements, though it holds small-business set-aside designations on select awards, and manufactures goods across NAICS 338910 (Gasket, Packing, and Sealing Device Manufacturing) and related industrial categories, with PSC concentration in packing and gasket materials (Miscellaneous Electrical and Electronic Components and Packing and Gasket Materials codes).

United Seal & Rubber's customer footprint centers on Defense Logistics Agency entities, which account for 78% of recent award count and 88% of combined potential value. Defense Logistics Agency Land and Maritime leads with 133 awards valued at $1.1 million combined potential value, followed by Defense Logistics Agency Troop Support Hardware (63 awards, $223 thousand), and Defense Logistics Agency Aviation (20 awards, $1.3 million). Naval Sea Systems Command and Naval Information Warfare Systems Command round out the top tier with 15 and 8 awards respectively. Work is performed at the company's Dunwoody, Georgia location and Portsmouth, Virginia, with distributed delivery to military depots across the continental United States and overseas locations.

Recent representative prime awards include a $11.97 million firm fixed-price purchase order from Naval Sea Systems Command in December 2024 for gasket sheets (total small business set-aside), a $37 thousand DLA Land and Maritime order in January 2024 for packing with retainer (NSN 8510383017), and a $14.37 thousand Naval Information Warfare Systems Command purchase order in October 2024 for gasket sheets (total small business set-aside). In December 2025, the company secured a single-award Indefinite Delivery Contract with DLA Land and Maritime valued at $350 thousand through December 2026 for Shielding Gasket components (NSN 5999011827326), structured as an automated IDC with guaranteed minimum quantity of 13 units against initial order of 91 units and estimated four orders per year.

Activity has been volatile — fourteen awards in 2022, declining to five in 2023 and recovering to nine in 2024, with seven awarded through the first five months of 2025. The company's combined potential value across all recent awards stands at $3.2 million against $8.3 million in obligated dollars, indicating mature contract performance and draw-down against prior-year awards. The top parent vehicles are legacy Indefinite Delivery Contracts under Army and Navy platforms: DAAH0189D0145 and DAAH0189D0052 (Army), N0016406D8981 (Navy), and SP093505D5X08 (DLA).

United Seal & Rubber operates as a subcontractor to Lockheed Martin Corporation on defense primes, supplying EMI/environmental closeout materials and gasket seals for F-35 aircraft long-lead-item procurement and Hellfire and JAGM missile production (multiple sub-awards dated August 2024 and earlier). The company has a long contracting history with the federal government — the source data spans from 1988 to present — positioning it as an established supplier of precision-engineered elastomer components to defense logistics and naval shipboard applications.
