Heat Resistant Electrical Insulating Tape 9–25mm | Wiring Loom

Heat Resistant Electrical Insulating Tape for Car Wiring & Cable Harness Protection

Keep your vehicle's wiring neat, protected, and performing at its best with this professional-grade Electrical Insulating Harness Tape. Available in four widths — 9mm, 15mm, 19mm, and 25mm — this versatile tape is engineered to wrap, bundle, and protect cable looms, wiring harnesses, and electrical runs in automotive, marine, and DIY electrical applications.

Why Choose This Harness Tape?

• Heat Resistant: Withstands elevated temperatures commonly found in engine bays and under-dash environments, maintaining its integrity where standard tapes fail.
• Waterproof & Moisture Resistant: Creates a reliable barrier against water ingress, humidity, and fluid exposure to keep connections dry and secure.
• Excellent Electrical Insulation: High dielectric strength ensures cables remain safely insulated, reducing the risk of shorts or electrical faults.
• Flexible & Conformable: Wraps tightly and smoothly around cables, conduits, and harnesses of varying diameters without cracking or losing adhesion.
• Four Width Options: Choose 9mm for tight runs and connectors, 15mm for standard bundles, 19mm for mid-size looms, or 25mm for large harnesses and trunk cables.
• Strong Adhesive Bond: Stays in place in demanding environments — vibration, heat, and movement won't cause it to unravel or peel.
• Clean, Professional Finish: Leaves wiring looking tidy and factory-fresh — ideal for restorations, custom builds, and everyday repairs.
