Perfect for sealing coaxial cable connections to protect against signal loss. Suitable for all cable joints. Cassette silicone rubber has strong resistance to water, soil, or chemicals. Long-term reliability for all antenna cables. Self-adhesive and cost-effective. This product is mainly suitable for protecting the insulation of cables not exceeding 1KV in a working environment below 80 degrees, waterproof and moisture-proof sealing of electrical connections, and protection of intermediate joints and sheaths, etc. Features: Special rubber belt, high tensile strength, high elongation, good resilience, high pressure resistance, excellent airtightness, excellent weather resistance and aging resistance; strong corrosion resistance, non-absorbent, in water and high voltage resistance and volume resistivity hardly decrease in humid environment; the insulating layer is fused into one after packaging, and it will never fall off. The packaging is firm, neat and clean. Instructions: 1. When using, first remove dust and other impurities from the cable connector 2. Remove the release paper and stretch the tape to 1-2 times the original length, so that the sticky adhesive layer of the tape (i.e., the side with the release paper) faces the surface of the wound cable; with an overlapping winding rate of about 50%. It is recommended that the maximum stretching length should not exceed 4 times the original length of the tape. 3. The starting point and ending point of the winding should be 30-50mm beyond the edge of the joint 4. It is recommended to use PVC polyvinyl insulation tape when using waterproof tape Color: Black Shipped Quantity: 1 piece Size: 0.3mm*19mm*2.5m
