F4 Tape

Military Grade Silicone Tape F4 Tape, manufactured to US Military Specifications, is rugged, versatile, and used by the US Armed Forces in BDAR Kits. Waterproof and airtight, it fuses underwater, resists fuels, oils, and solvents, and tolerates temperatures up to 500°F. F4 Tape never gets sticky or gummy and is unaffected by Mil-Spec corrosion inhibitors like ACF-50. It has a triangular cross-section with center guideline, making it easy to apply with a consistent thickness.
