Manufacturing Lancaster, NY 201–500 employees Founded 1963 Privately Held

Sealing Devices manufactures gaskets, o-rings, EMI shielding, and custom molded rubber components for aerospace, industrial, and transportation OEMs. The company runs a legacy enterprise stack (Oracle ERP, SAP, NetSuite) with no active tech modernization—a pattern typical of capital-intensive manufacturers—while its pain-point list (estimating accuracy, labeling standardization, quality nonconformance tracking) suggests operational bottlenecks in order-to-cash and quality workflows that drive active hiring in manufacturing and operations roles.
