Sealing Specialists and Service

What Sealing Specialists and Service does

Sealing Specialists and Service Co. is a privately held, founder-owned industrial business headquartered in Glenshaw, Pennsylvania (Pittsburgh metro), founded on October 1, 1976 by current CEO and owner Tony Urso. The company operates three integrated service lines: (1) custom manufacturing using CNC laser cutting (4000W Prima system with 5'x10' shuttle table), 50,000 PSI OMAX waterjet cutting, HAAS lathe with DMH software, and digital knife cutting for gaskets; (2) in-house repair and rebuild services for seals, pumps, and hydraulic cylinders (including cylinders up to 1500mm/60in bore and 22m/72ft stroke); and (3) authorized distribution of industrial seals, o-rings, and gaskets sourced from leading brands including Parker, Flowserve, Garlock, Grainger, Loctite, Royal Purple, Hallite, Greene Tweed, and T-Lon.

The company is ISO 9001:2015 certified and operates with 25 trained employees from its Glenshaw facility, with an additional 22,000 square foot facility expansion underway. It serves industrial manufacturers, municipalities (water supply and wastewater treatment), utilities, natural gas suppliers, water treatment companies, and the steel industry across the United States and Canada. Core products include hydraulic and pneumatic seals, o-rings in imperial and metric sizes, custom gaskets, and a broad range of precision-cut parts (brackets, shims, dog-bones, grommets, diaphragms, expansion joints).

Revenue is generated through quote-based, sales-led pricing across all three service lines, with distribution and custom manufacturing driving transactional volume and repair services providing higher-margin professional services revenue. The GTM motion is direct — phone (412-487-8282), toll-free (1-866-487-8283), and email ([email protected]) — supplemented by an SEO-optimized website. There are no public revenue disclosures, no institutional or private equity backing, and no app, API, or digital product offerings.
