HI-TAK^® Fuel Access Panel Gaskets

Polyurethane Fuel Tank Access Panel Gasket and for Optimal Environmental Sealing, Repairs, and Maintenance of Avionic Assemblies.

Av-DEC offers highly durable, polyurethane fuel access panel gasket systems for aircraft repairs and sealing applications. These gaskets are die cut with diverse profiles and configurations to effectively protect tank access doors and other assemblies from corrosion. Customers can choose to use Av-DEC range of fuel access gasket systems to efficiently seal aircraft assemblies and structures from the effects of natural elements. The gasket systems ensure the tight tolerances and dimensions required for optimal aircraft functions are maintained. The HI-TAK fuel tank access panel gasket systems meet Federal Aviation Administration (FAA) airworthiness standards. They employ an "Apply and Fly™" application procedure which is perfect for real-time repairs and maintenance activities.

Av-DEC polyurethane fuel tank access panel gaskets integrate the use of polyurethane sealants to provide an environmental seal. The instant benefits with every application are:

• Effective protection of components against wear and tear from constant use.
• An effective environmental seal that protects wing skin, tanks, panels, and door surfaces from high-stress environments.
• Effective sealing of voids, fastener holes, and surface imperfections from corrosive agents such as moisture, oil, debris, and aviation fuel.
• "Apply and Fly" approach that eliminates long cure times and the downtime they produce.
• Indefinite shelf-life when stored according to specified recommendations and protected from UV exposure, resulting in no wasted inventory.

Polyurethane-Driven Resistance to Natural Elements

Av-DEC HI-TAK fuel tank access panel gasket systems utilize a polyurethane sealant which allows the gasket system to remain flexible under diverse environmental conditions. The gaskets will function optimally under fluctuating temperatures from -65°C to 135°C (-85°F to 275°F). You can also count on its impermeability to moisture under fluctuating temperatures and pressure. Some of the advantages to gain from the flexible and cohesive Av-DEC fuel tank access panel gaskets include:

• It retains its optimal dimensions after contracting or expanding due to natural elements which keeps corrosion out in any condition.
• Lightning Strike Protection. The gasket systems are built with aluminum meshes that provide conductive pathways for lightning strikes, therefore helping to protect assemblies from excessive electrical surges.
• Enhanced Environmental Protection. It protects tank access doors and assembly surfaces from moisture, humidity, and oxidation which reduces costly replacements.

Enhanced Resistance to the Effects of Wear and Tear

Abrasions, cracking, looseness, and cuts affect the structural integrity of aviation components such as tank access doors, wing skins, and hardware surfaces. Users can apply the die-cut polyurethane fuel tank access panel gasket systems to protect structures from such wear and tear caused by constant use. The benefits to gain by enhancing the resistance profile of aircraft components include:

• Reduces Fretting. It reduces fretting or wear when applied on wing skins and door surfaces.
• Excessive Vibration Resistance. The gasket systems protect avionic components from the deforming effects of excessive aircraft vibrations.
• Eliminates Residual Corrosion. Av-DEC gasket systems are non-hazardous and do not leave residues behind. This eliminates the possibility of debris and solvents acting as corrosive agents.

Av-DEC Polyurethane Gels Compliment HI-TAK Fuel Tank Access Panel Gaskets for Maximum Protection

It is recommended that fuel-resistant polyurethane gel sealants be used to achieve complete protection. The polyurethane gel is non-hazardous and does not contain volatile organic compounds (VOC). The polyurethane gel is applied on open surfaces and works with the gasket to completely seal off moisture and liquids from surfaces. Users gain multiple benefits by applying Av-DEC polyurethane gels, including:

• Real-time Void Fills. The gel flows under compression and fills up voids, fastener holes, and bores which eliminates surface imperfections.
• Complete Sealing Action. The polyurethane gel seals off surfaces around avionics assemblies from the environment which increases the assembly's lifespan.
• Eliminates Moisture Build-up. The gel secures fastening systems and assemblies from the moisture build-up that occurs during constant aircraft operation. This eliminates corrosion, cracking, and leakage.

Precise Gasket Configurations Built for Specific Applications:

• Gaskets that seal the outer surface of fasteners and components.
• Gaskets with pinholes to accommodate fasteners and pins.
• Gaskets with aluminum meshes for electrical conductivity.

If sealing requirements are unique, Av-DEC experienced technicians can custom-build gasket system configurations to meet users" specific needs.
