The A-8574 is premium Nitto self-amalgamating butyl rubber tape, designed to provide long-lasting electrical insulation, moisture sealing, and environmental protection for RF connectors, coaxial cable terminations, and electrical joints. Measuring 20mm wide × 0.76mm thick × 10 metres long, this self-bonding tape forms a seamless waterproof barrier without the need for adhesive, making it an essential accessory for professional communications installations.
Ideal for sealing N-type, 7/16″ DIN, UHF (PL259), BNC, TNC, SMA, and other RF connector interfaces, the A-8574 protects against water ingress, dust, corrosion, and contamination that can degrade RF performance and shorten equipment life. It is equally suited to cable splicing, electrical insulation, and weatherproofing applications across telecommunications, broadcast, defence, emergency services, mining, marine, transport, and industrial infrastructure.

For maximum environmental protection, ZCG Scalar recommends overwrapping the completed butyl rubber layer with a UV-stabilised PVC insulation tape, extending beyond both ends of the amalgamating tape to create a durable, weather-resistant outer seal suitable for prolonged outdoor exposure.
Whether installing a 4WD UHF radio, marine antenna, cellular system, microwave link, or high-power broadcast transmission line, correctly sealing every external RF termination is essential for maintaining low insertion loss, preventing corrosion, and maximising long-term system reliability.
Combining self-fusing insulation, excellent waterproofing performance, and trusted Nitto quality, the A-8574 from ZCG Scalar is an essential installation accessory for protecting professional RF and electrical systems in harsh outdoor environments.
