About GORE SKYFLEX Aerospace Materials

Relied on by the military for years, GORE SKYFLEX Aerospace Materials are available in form-in-place (FIP) tapes or die-cut gaskets. Gore constructed these solutions by including proprietary material, expanded polytetrafluoroethylene (ePTFE). This makes them resistant to fuels, oils and hydraulic fluids, as well as corrosion. They also have a low environmental impact and deliver benefits such as the following:

No Mess or Curing Required

Gore’s materials are dry, lightweight sealants that remain flexible and compliant over multiple open/close cycles. They do not require any curing on panels, fairings or floorboards, easing installation across F-16 applications. Once the material is applied and the panels are fitted, the aircraft is fully operational.

Durable Protection against Aerospace Conditions

These single-component materials provide superior defense against extreme temperatures, fluids and other environmental hazards, outlasting alternatives and leading to decreased maintenance downtime and reduced manufacturing cycles.

Approved Applications for F-16 Aircraft

Gore’s aerospace materials are tested and pre-qualified to meet the high standards of the United States Air Force and handle even the most volatile aerospace conditions during vital missions. They are approved for use in the following F-16 technical orders (TOs):

  • TO 1-1-691: Aircraft Weapons System Cleaning and Corrosion Control
  • 1F-16C-2-00GV-00-1: General Vehicle Organizational Maintenance
  • 1F-16CJ-4-28: IPB Fuel Systems
  • 6J14-2-39-2: 370-Gallon External Fuel Tank

Specifically, GORE® SKYFLEX® Aerospace Tapes, Series 100 and 110, should be used on panels that require environmental sealing. This material may be used as an alternate to AMS-3276 or AMS-3277 (formerly MIL-S-83430) when installing new access door or panel sealing. Meanwhile, GORE SKYFLEX Aerospace Tapes, 720 Series, also known as SKYFLEX “OP” Environmental Sealant Tape (Fuel/ Hydraulic Areas) is a non-hazardous and reusable alternative to FIP polysulfide sealant.

Further, GORE® SKYFLEX® Aerospace Gaskets, 720 Series, is intended for use on fuel system panels, as well as on non-fuel system panels.

Ensuring Inspections to Determine Need for Repairs and Replacements

Inspect the sealant whenever the panel is removed, as well as prior to reinstallation and reuse. Note that if it has been damaged, its sealing ability may be degraded, requiring repair or replacement as specified in the appropriate technical manual and Gore’s resources.

NOTE: If damaged, GORE SKYFLEX Aerospace Gaskets, 720 Series, in fuel system panels should be replaced in their entirety. If GORE SKYFLEX Aerospace Tapes, 720 Series, are damaged in non-fuel system panels, refer to the appropriate inspection and repair criteria.
