Waterproof your connections & fittings against moisture and corrosion with Coax Seal Connector Sealing Tape. Coax Seal makes a waterproof seal on any connections for Security Cameras, WiFi, Satellite, Ham Radio, power connections and coax of all kinds. Forms and seals around odd-shaped and difficult fittings. Stays flexible at any temperature for years, yet allows for quick disconnection when needed. Simply wrap any connection, then mold the Coax Seal around it to force out air and create a smooth surface that won't hold moisture. Effective at temperatures from -30 to +180F (-35 to +82C). Adheres to polyvinyl and vinyl outer coax jackets better than anything out there!
