Inner thermoplastic adhesive flows under heat and bonds to insulation, creating a 360° waterproof seal. Essential for bilge wiring, solar runs, and outdoor joints.
Same black, every spool, every lot. Tracked and documented. Available in 9 colors for OEM and custom-label programs.
Rated for continuous high-temp service. Fully shrinks at 120°C — no need to overheat and risk charring surrounding insulation.
