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.
