GORE GSC21-95035-010 (1.4-Inch-Roll)

GORE™ SKYFLEX™ Aerospace Materials

Overview

GORE™ SKYFLEX™ Aerospace Materials are a portfolio of engineered expanded polytetrafluoroethylene (ePTFE) tapes and gaskets developed to provide reliable sealing, abrasion protection, corrosion prevention and gap filling for aerospace faying surfaces. Proven in service for more than 20 years, these lightweight, non-curing materials are specified by leading civil and military aircraft OEMs and provide a reusable alternative to traditional form-in-place (FIP) sealants. Designed for demanding aerospace environments, SKYFLEX™ materials maintain performance after repeated opening and closing cycles while resisting fuels, hydraulic fluids, vibration, UV exposure and harsh operating conditions.

Why This Product is Chosen for AOG / MRO

• Eliminates curing time compared with traditional form-in-place sealants
• Reusable sealing materials withstand multiple access panel removal cycles
• Excellent protection against abrasion, corrosion and environmental contamination
• Highly conformable material compensates for manufacturing tolerances and uneven gaps
• Reduces maintenance labour, aircraft downtime and life-cycle costs
• Lightweight construction supports aircraft weight reduction initiatives

Practical Suggestions for Your Team (AOG Mindset)

• Select the appropriate SKYFLEX™ series according to fluid exposure, gap size and compression requirements
• Use 520 or 720 Series where long-term jet fuel sealing performance is required
• Choose 730 Series for applications exposed to SKYDROL®, turbine oils or aggressive aviation fluids
• Use reusable tape systems on frequently opened access panels to reduce maintenance time
• Specify custom gasket dimensions where production tolerances require tailored sealing solutions
• Store adhesive-backed materials within the recommended shelf life to maintain installation performance
