Sealing Specialists & Service Co

Sealing Specialists & Service Co, a small business based in Glenshaw, Pennsylvania, manufactures and supplies gaskets, O-rings, preformed packing materials, rubber sheets, and sealing compounds to the federal government as a prime contractor operating entirely under Total Small Business set-asides. The company competes exclusively in set-aside categories, with 100% of its recent prime awards designated for small business participation, and operates without identified subcontractors across its federal portfolio.

Sealing Specialists' customer base is almost entirely concentrated with the Naval Supply Systems Command, which accounts for 1,318 of 1,331 total awards and $112.6 million of the $112.7 million combined potential value—a 99.9% concentration. The company holds two foundational indefinite delivery vehicles with NAVSUP: a $28 million multiple-award Blanket Purchase Agreement covering Federal Supply Classes 5330 and 5331 (gaskets, O-rings, packing materials, rubber sheets, and sealing compounds) awarded June 6, 2023, and expiring April 3, 2026; and a $40 million single-award BPA for whole body valves and valve piece parts under FSC 4820 in support of RADCON requirements, awarded December 15, 2022, and running through December 14, 2027. The company issues task orders against these vehicles at firm fixed-price terms, with recent calls ranging from under $500 to $119,440.23 and typical six-month completion windows. Representative prime work includes a $119,440.23 gasket purchase order awarded October 18, 2023; a $87,433.03 O-ring BPA call from March 1, 2024; a $49,009.04 gasket BPA call awarded December 5, 2024; and a $36,678.72 packing material BPA call awarded March 24, 2025, all under NAVSUP and designated Total Small Business set-asides.

Activity has contracted in recent years, declining from 91 awards in 2022 to 49 awards in 2026, representing a five-year decline of 46%. Thirty awards with a combined potential value of $450 thousand face ultimate completion within the next twenty-four months, creating near-term recompete exposure. The company's award portfolio concentrates in NAICS 325991 (Gasket, Packing, and Sealing Device Manufacturing), which represents 958 of the total 1,331 awards. Product-line concentration reflects this focus: 982 awards are classified under PSC code 5330 (Packing and Gasket Materials), 144 under O-Ring procurement, and 69 under Rubber Fabricated Materials. Sealing Specialists has held federal contractor status since at least 1991 and has established itself as NAVSUP's incumbent supplier for mission-critical sealing components supporting naval logistics, maintenance, and fleet operational readiness across the Navy and Marine Corps' global supply chain.
