What State Seal Company does
State Seal Company is a U.S.-based, privately held manufacturer and distributor of standard and custom-engineered seals, gaskets, and converted products, founded in 1966 and headquartered in Chandler, Arizona, with a second facility in Fort Mill, South Carolina. The company operates across 14 vertical markets including aerospace, military, semiconductor, life sciences, automotive, chemical processing, fluid power, telecommunications, power generation, renewable energy, consumer products, general industrial, transportation/aftermarket, and small engine. Its offering spans 14 core product lines — gaskets, seals (O-rings, hydraulic, PTFE), die-cut parts, liquid-dispensed Form-In-Place gaskets, EMI/RFI shielding, fluid power seals, custom molded products, composite seals, high-temperature materials, thermal interface materials, vibration control, foams and filtration, sanitary seals, and tapes/adhesives — supported by certifications including AS9100D, IATF 16949, ISO 9001, and ISO 14001.
The company's core technology stack centers on three differentiated manufacturing methods: robotic Form-In-Place (FIP) liquid gasket dispense applied to flanges as small as .035 inches, CNC die-less knife cutting for rapid prototyping without hard tooling, and a converted CNC machine moving in X/Y/Z axes for high-precision bead placement. These capabilities allow production runs from 10 parts to 10 million parts, with quote-based pricing and no publicly disclosed price list. Distribution leverage is provided through authorized-fabricator relationships with tier-1 materials OEMs — Parker-Hannifin, Parker Chomerics, DuPont Kalrez, 3M, Wolverine, Interface Solutions, Rogers, Henkel (Berquist), Saint-Gobain, and Garlock.
The business model is sales-led, driven by technically trained inside and outside sales staff who provide product selection assistance, design and engineering support, and customer service. Lead generation relies on a 'Request a Quote' website funnel, supplemented by technical blog content and downloadable capability guides. The company serves only the U.S. market, has no disclosed parent, no external funding, no acquisitions, and no named end-customers in source materials; revenue and headcount trend data are not publicly disclosed.
