Heat Shrinkable Tubes/Heat Shrink Sleeves
HEAT SHRINK FLAME RETARDANT TUBING
Heat Shrink Flame Retardant Tube is a high-quality tubing made from cross-linked material.
These tubes serve as waterproof seals for cable terminations and joints, providing corrosion protection, environmental sealing, and mechanical protection for pipes and connections. Additionally, they are used for insulating underground and aerial connections in CATV plants, CCTV systems, and control cable splicing joints.
Technical Qualification Report : QR 1014
