W.L. Gore, Elkton, MD, has introduced the GORE™ SKYFLEX® Aircraft Fuel Sealant that resists UV and aging and is designed for temperature applications up to 356 °F (180°C). The fuel sealant is a reusable, non-curing, non-hazardous, form-in-place sealant that provides protection against corrosion, water ingress, fuels, and other environmental influences including oils. It provides fuel sealability, is resistant to leakage, and requires less compression to seal than traditional sealants. It also offers controllable panel flushness.

GORE™ SKYFLEX® Aircraft Sealant is a PTFE-based sealant and unlike rubber gaskets, PTFE does not age or become hard and brittle. The sealant has been approved for use with 1F-16C-2- 00GV-00-1 and LMAME002. It also meets the following specifications: ASTM-D-792 density requirements; AMS3255 low temperature flexibility; ASTM-F-152 method C tensile strength; ABR5-0127 shrinkage; PM0110-1A load to seal; and PM0110/B reusability. The fuel sealant is available in various standard size sheets and tapes. Nominal thickness of both sheets and tapes are 0.4mm, 0.6mm, 0.8mm, 1.0mm, and 1.2mm. Standard sheet sizes range from 6 × 12" to 18 × 36". Die cut gaskets are available upon request. Tapes are available in widths of 0.5", 0.75", 1.0", 2.0", 3.0", 4.0", and 5.0"
