530 – High Performance Self-Fusing Silicone Sealing Tape for Coax Cables & Electrical Repairs – 30 mil Thick 1.5 in x 15 ft – Black (Black)

E/FUSING 530 by Midsun is a premium-grade self-fusing silicone tape engineered for coaxial cable sealing, electrical insulation, and emergency repairs in the toughest environments. This non-adhesive, self-bonding tape bonds only to itself—forming an airtight, watertight, and UV-resistant barrier that won’t crack, peel, or leave sticky residue. Unlike traditional vinyl or butyl tapes, E/FUSING 530 remains stable at extreme temperatures from -65°F to 500°F, making it perfect for both indoor and outdoor use. Our heavy-duty 30 mil thickness delivers superior abrasion resistance and insulation while easily conforming to uneven, sharp, or rugged surfaces; ideal for RF connectors, antenna terminations, and weather-exposed coaxial cable junctions. At 1.5" wide, it wraps faster and cleaner with fewer seams, saving time and reducing installation fatigue.

• Proudly Made in the USA: Manufactured and tested in the United States using high-grade silicone. Trusted by professionals in the electric utility and telecom industries.
• Seal Coaxial Cable & Electrical Connectors from Moisture, Dust & Corrosion: Provides a long- lasting, weatherproof barrier for RF connectors, antenna terminations, and coax cable splices in outdoor or harsh environments.
• No Adhesive,Self-Fusing Silicone Tape Bonds to Itself: Leaves zero sticky mess behind; tape forms a permanent fusion bond without glue or residue, easy to apply and remove.
• Waterproof, UV-Resistant, Chemical & High Temp Tolerant: Performs in extreme temperatures from -65°F to +500°F and resists saltwater, oil, ozone, and most chemicals.
• Flexible: Apply with Tension for Secure Fusion and stretches up to 3x its length during installation. Watch the application demo in the photo gallery to see it in action.
• Built Tough for Industrial & Utility Applications: 30 mil thick and 1.5 inches wide for maximum insulation, abrasion resistance, and faster wrap coverage with fewer seams.
