Av DEC

What Av DEC does

Av-DEC, operating legally as Aviation Devices & Electronic Components, LLC, is a Fort Worth, Texas-based specialty materials manufacturer founded in 1997 by two aerospace engineers. The company designs and produces proprietary polyurethane and polyurea-based corrosion prevention products for the aviation industry, anchored by its HI-TAK product family. Core offerings include pre-cured die-cut gaskets (antenna, fuel access panel, panel, and connector gaskets), polyurethane rolled sealants (PRS) such as HT3935-7, TufSeal, StructureSeal, StretchSeal, and ThinSeal, two-component injectable and sprayable sealants, engineered sealing systems (Floorboard, TripleSeal, QuadSeal), Ox-Block corrosion inhibiting compounds (CIC), and custom-engineered NAVSEA-qualified gaskets for naval and military applications. The underlying technology relies on pre-cured polyurethane gels encapsulated around mesh carriers (aluminum, fiberglass, nylon, PTFE, polypropylene) to deliver environmental sealing, EMI protection, and lightning strike resistance qualified against MIL-B-5087B, MIL-STD-464, MIL-STD-1310H, CID A-A-59398A, 14 CFR Part 25 Appendix F, and ASTM B117 3000-hour Salt Fog standards.

Av-DEC sells directly to four primary enterprise segments: aerospace OEMs for production sealing, commercial airlines for fleet maintenance, MRO organizations for repair and overhaul, and military/defense organizations (including NAVSEA) for specialized applications. The company employs a field-based technical sales model with on-site customer support and engineering collaboration for custom gasket development, supplemented by participation in five major 2026 industry trade shows including MRO Europe in Amsterdam. Pricing is quote-based and not publicly disclosed; many SKUs are available under National Stock Numbers (NSNs) for U.S. military and government procurement, and the company is AS9100 and ISO 9001 certified. Products are deployed across approximately 5,000 aircraft and more than 1,000 custom antenna footprints globally, with founders retaining principal ownership and no external funding rounds or revenue figures disclosed.

Core offering

Av-DEC manufactures and sells proprietary polyurethane-based corrosion prevention sealants, gaskets, rolled sealants, injectable/sprayable sealants, and corrosion inhibiting coatings used by aerospace manufacturers, commercial airlines, MRO organizations, and military/NAVSEA customers. Products are designed for aircraft structures, antennas, panels, connectors, fuel access points, and floor/cargo areas, with an "Apply and Fly" pre-cured design that enables immediate return-to-service installation. The company also offers custom-engineered sealing solutions developed in direct collaboration with its technical sales and engineering teams.

Product overview

Av DEC is a provider of corrosion prevention solutions for aviation, offering a comprehensive portfolio of polyurethane and polyurea-based sealing products. The product lineup centers on HI-TAK brand gaskets (antenna, fuel access panel, panel, and connector gaskets), Polyurethane Rolled Sealants (PRS) including PRS HT3935-7, TufSeal, StructureSeal, StretchSeal, and ThinSeal, and injectable sealants (Self-Leveling Green, Self-Leveling Clear, Thixoflex series, TufStuff). Additional offerings include SpraySeal sprayable sealants, Sealing Systems (Floorboard, TripleSeal, QuadSeal), Ox-Block corrosion inhibiting compounds, Aircraft Kits, and NAVSEA gaskets for naval applications. The company follows an 'Apply and Fly' philosophy enabling real-time installation without cure time, and products are certified to AS9100 standards.
