Sealing Specialists & Service Co

Sealing Specialists & Service Co, a Glenshaw, Pennsylvania–based small business, manufactures and supplies gaskets, O-rings, preformed packing materials, rubber sheets, and specialized sealing compounds to the Department of the Navy as a prime contractor across two large blanket purchase agreements running through 2026 and 2027. The vendor competes under Total Small Business set-asides on virtually all recent task orders and operates without identified subcontractors.

The company's federal footprint is heavily concentrated in naval supply: the Naval Supply Systems Command accounts for 1,287 of 1,300 awards and $112.1 million of $112.2 million in combined potential value—effectively 100% customer and dollar concentration. The remaining activity consists of four small Defense Logistics Agency awards and one Department of Energy award. Sealing Specialists has served this customer base since at least 2002 and has maintained its relationship through a structured BPA posture that enables rapid procurement of mission-critical sealing components for Navy and Marine Corps logistics and maintenance programs.

The vendor holds two core IDV vehicles with Naval Supply Systems Command: a $28 million multiple-award Blanket Purchase Agreement (N0010413A7013 through successors) covering Federal Supply Classes 5330 and 5331—gaskets, O-rings, packing materials, rubber sheets, and sealing compounds—with 345 task orders, and a $40 million single-award BPA (awarded December 15, 2022, running through December 14, 2027) for whole body valves and valve piece parts under Federal Supply Class 4820 in support of RADCON requirements. Recent call activity against the FSC 5330/5331 vehicle has included orders ranging from under $500 to $119,440.23, with individual calls consistently designated Total Small Business set-asides and firm fixed-price structures. Task order completion windows typically run six months from award. The second BPA, while established for valve components, has generated calls for O-rings and related sealing products; recent calls valued at $3,222.40 and $5,007.36 reflect ongoing demand.

Award activity has declined year over year, from 91 awards in 2022 to 18 through April 2026—a signal of maturation in the customer relationship or consolidation of order patterns. Combined obligated dollars total $9.6 million against $112.2 million in potential value, indicating that most awards represent ceiling values or multi-year task order vehicles not yet fully invoiced. Twelve awards with combined potential value of $272 thousand reach ultimate completion within the next twenty-four months and represent recompete exposure for the vendor.

Capability concentration reflects the vendor's narrow specialization: 938 awards fall under NAICS 325991 (Gasket, Packing, and Sealing Device Manufacturing), 114 under miscellaneous machinery manufacturing, and 45 under rubber product manufacturing. PSC coding shows 962 awards for packing and gasket materials, 141 for O-rings, and 68 for rubber fabricated materials. This deep focus on a single customer's sealing-products portfolio, combined with the Total Small Business set-aside posture across the prime footprint, positions Sealing Specialists as a specialized supplier with limited pipeline diversification but established incumbent status on the Navy's critical supply chain for gaskets and sealing components.
