Av-DEC

Av-DEC makes corrosion prevention products for aircraft. The company says it has worked on aviation corrosion problems since 1997. Its website describes its work as the science that stops corrosion. Its products serve aerospace manufacturers, air carriers and maintainers.

Av-DEC makes HI-TAK gaskets. They are die cut from polyurethane sealant, which the company says is non-hazardous and gives a long-term environmental seal. The gaskets come pre-cured, contain no VOCs or silicone, and use an Apply and Fly design. They are available with conductive or non-conductive mesh. Types include antenna, fuel access panel, panel, connector and custom gaskets.

The company also makes rolled sealants, known as PRS, which it describes as a pre-cured polyurethane tape sealant. Its injectable sealants allow repair long after the first application, and they include self-leveling and Thixoflex versions. SpraySeal sprayable sealants bring the same sealant technology to a spray form. Its sealing systems include a floorboard sealing system, a dual wrap connector, HI-TAK TripleSeal and HI-TAK QuadSeal.

Av-DEC also offers Ox-Block corrosion inhibiting compounds and aircraft kits. The kits are combinations of polyurethane sealing materials for cold application on existing electrical connectors and harnesses. The company also makes conductive gaskets for naval and marine applications, which help prevent corrosion and reduce EMI.

The website lists a training center with installation documents and videos, and technical articles on topics such as corrosion basics, causes of corrosion, dissimilar metals and corrosion inspection. Av-DEC has commercial and military technical sales teams that help customers choose a product or work on a custom solution.

The company says it works with customers on custom solutions and new products. Its interactive airplane product selector helps users find the right product. The site also lists military approvals and a flammability test.

Trade shows listed on the site include MRO Europe in Amsterdam from October 27 to 29, 2026, the AAAA Joseph P Cribbons Aviation Product Symposium in Huntsville, Alabama in November 2026, and MRO Middle East in February 2027.
