What AP Services does
AP Services, operating as a brand within Curtiss-Wright Corporation's Nuclear Division, supplies fluid sealing technologies and services to commercial nuclear and fossil power plants, chemical and petrochemical facilities, the U.S. Department of Energy, the U.S. Department of Defense, OEMs, and general industrial customers. The portfolio centers on manufactured sealing components — mechanical packing, gaskets, textile products (weld cloth, fire blankets), specialty products (expansion joints, mechanical seals, o-rings), graphite pressure seals, and nuclear safety-related products — augmented by a branded sub-brand ecosystem: sealTECH™ for proprietary valve packing technology, sealPRO™ for valve-packing database software, sealID™ for product identification and tracking, and sealOE™ for OEM sealing solutions.
The company's core technical differentiation rests on proprietary valve packing technologies that claim the lowest leak rate and friction in the industry, manufacturing capability built around CNC-driven water jet cutters, 2D scanners, and packing braiders, and a Quality Assurance Program certified to 10CFR50 Appendix B, 10CFR21, and NQA-1 — the principal nuclear regulatory frameworks governing safety-related suppliers. Supporting services include on-site fluid sealing support, turn-key valve repack services, and warehouse evaluations, all delivered via an enterprise field-sales motion through Curtiss-Wright's sales infrastructure.
The revenue model is hardware sales of manufactured fluid sealing products with quote-based B2B pricing typical of industrial nuclear supply. The business is anchored in a regulatory moat (nuclear quality certifications) and a concentrated addressable buyer base (U.S. commercial utilities, federal nuclear sites). Recognitions include Utility Services Alliance and Constellation 'Supplier of the Year' awards and NEI TIP awards for packing and graphite pressure seal innovation. AP Services is headquartered in Middleburg Heights, Ohio, and operates with 101-250 employees as a wholly-owned operating unit of the publicly traded Curtiss-Wright Corporation (NYSE: CW).
