GORE® SKYFLEX® Aerospace Materials for Sealing and Surface Protection
Gore’s dry, lightweight aircraft sealants effectively protect many surfaces, simplify installation, increase throughput, improve safety and reduce lifecycle costs.
Reliable Sealing & Surface Protection
GORE® SKYFLEX® Aerospace Materials seal panels and protect surfaces from mechanical forces and harsh contaminants that can severely damage aircraft and helicopter structures. Unlike traditional curing materials, our tapes and gaskets don’t require any cure time, which reduces installation steps and simplifies the process.
Durable & Predictable Performance
Unlike low-temperature cure materials for aircraft, GORE SKYFLEX Aerospace Materials are manufactured with unique features that make them more durable against challenging environmental factors and aircraft conditions, including:
- chemically inert, non-hazardous materials
- temperature- and corrosion-resistant materials
- dry, lightweight, highly conformable materials
- available in a variety of material sets, forms and sizes
Our SKYFLEX tapes and gaskets provide many benefits that simplify aircraft assembly, increase availability and throughput, and reduce lifecycle costs, like:
- reliable, predictable sealing and surface protection and gap-filling
- proven resistance against wide temps, corrosion, abrasion, chemicals, fuels and more
- easier, quicker installation with fewer process steps and no cure time
- less replacements, rework and lifecycle costs with reusable seals
- no operator certification, training or special material handling required
- low environmental impact and improved safety with non-hazardous materials
As one of the industry’s foremost aerospace materials suppliers, we thoroughly test GORE SKYFLEX Aerospace Materials to meet many strict requirements, like SAE AMS3255™.
They’re routinely specified by leading aircraft OEMs because of their proven reliable performance for decades in a variety of secondary structures and removable applications, like:
- access panels (wing, fuel, LE/TE & dry bay)
- floorboards & structures (cargo seal & passenger area seal)
- engine cowlings
- external fuel tank sealer
- fairings
- fuel bladder cavities
- helicopter tail boom covers
- wing D-Noses
- lighting assemblies
Our PX1 Series is specifically designed for permanent load-bearing primary structures requiring robust sealing and corrosion protection while maintaining structural integrity, like:
- fuselage joints (ribs, stringers, longitudinal/orbital joints, brackets)
- joints where fasteners provide low strain and still require a seal
Our materials are approved for use on many fixed-wing and rotary-wing aircraft by OEMs like Airbus, Boeing, Bombardier, COMAC and Embraer. They’re also qualified under Technical Order (T.O.) approvals for the F-16, F-35 and V-22, among many other aircraft, spacecraft and eVTOL programs.
For Legacy Applications
| Gore’s Material Set | Purpose | Application Uses |
|---|---|---|
| 100 Series Tape | Environmental Sealing | Best for big gaps and/or low compressive forces, like access panels and floorboards. |
| 110 Series Tape | Environmental Sealing | Ideal for big gaps and/or very low compressive forces, like access panels and floorboards. |
| 200 Series Tape | Environmental Sealing | Great for sealing gaps over 1 mm (0.04”), like composite fay surfaces and floorboards. |
For New Applications
| Gore’s Material Set | Purpose | Application Uses |
|---|---|---|
| 500 Series Gasket | Environmental Sealing | Best for applications requiring gaskets over 482.6 mm (19”) or gaps over 1 mm (0.04”) protecting access panels and wing-to-body fairings. |
| 520 Series Gasket | Fuel Sealing Protection | Ideal for applications that require gaskets over 457.2 (18”) with continuous exposure to fuels or engine oils. |
| 700 Series Tape & Gasket | Environmental Sealing and Surface & Hydraulic/Engine Oil Protection | Great for sealing most environmental applications, like access panels and leading edge, as well as protecting structures from high vibration, repeated access, abrasion, chafing, oils and fluids. |
| 720 Series Tape & Gasket | Hydraulic/Engine Oil & Fuel Sealing Protection | Perfect for access panels and other fay surfaces exposed to hydraulic/engine oils and de-icing fluids, as well as protection against vibration, abrasion, corrosion, and chafing. |
| PX1 Series Tape & Gasket | Load Bearing & Corrosion Protection | Designed for interfay corrosion protection of load-bearing primary (permanent) aircraft structure applications. Perfect for fuselage structural joints. |

Technical Information
GORE SKYFLEX Aerospace Materials are non-hazardous, improving environmental and operator safety. Our tapes and gaskets comply with global environmental regulations set forth by the Canadian Environmental Protection Act (CEPA), the European Chemicals Agency (ECHA) and the U.S. Occupational Safety and Health Administration (OSHA).
Before using our types of aircraft sealant in your application, carefully review our recommended standard practices below to reduce exposure to decomposition by-products.
Wet process installation involves extra time-consuming and labor-intensive steps that can make it difficult to meet production targets, maintenance schedules and budgets. But applying aircraft sealant is much easier and faster using GORE SKYFLEX Aerospace Materials.
Our tapes and gaskets eliminate process steps because there’s no mixing, masking, curing or re-assembling panels. There’s also no special handling required, cleanup after installation or hazardous waste disposal. They’re reusable and compliant over multiple open/close cycles, meaning you can easily remove aircraft panels during inspection without replacing or reworking our materials — unlike an epoxy polysulfide sealant.
