3M Scotch Super 33+ vinyl electrical tape .75in x 66ft — flame‑retardant, weather‑resistant insulation

Built for electricians, maintenance technicians, and DIYers who need a dependable insulating solution, this .75-inch by 66-foot roll combines conformability and weather resistance in a compact size. The tape stretches to follow uneven surfaces, resists flame spread and environmental exposure, and seals against moisture to protect electrical joints and splices. Included in this package is a handy bonus retractable pen from OfficeSupplyExpress for quick on-site labeling.

How does this tape hold up outdoors and in tough conditions?

The Scotch Super 33+ formulation resists UV degradation, rain, and temperature swings so outdoor splices remain insulated longer than ordinary tapes. It is flame-retardant and listed by UL for safety under electrical use conditions, making it suitable for exposed wiring and junctions.

• Vinyl backing resists sunlight and weathering
• Flame-retardant construction limits spread of fire
• UL-listed for electrical use and reliability
• Maintains adhesion in temperature extremes

Will this tape conform to awkward shapes and odd wiring bundles?

Yes — the tape stretches and molds around irregular shapes, creating a tight, moisture-resistant wrap that reduces gaps and improves mechanical protection. Its elasticity lets it form a consistent seal over splices, connectors, and bundled cables.

• High conformability for uneven surfaces
• Elastic recovery helps maintain tight wraps
• Useful on round, flat, and irregular cables
• Reduces need for multiple overlapping layers

How much tape is on the roll and is it convenient for field work?

This roll measures .75 inches wide and 66 feet long — compact enough to carry in a tool bag while providing enough length for many repairs and installations. The narrower width is ideal for precise wrapping on small harnesses, conduit, and control wiring, and the included retractable pen makes labeling quick and neat.

• .75-inch width for targeted application
• 66-foot length covers multiple jobs per roll
• Compact size fits pockets and pouches easily
• Bonus retractable pen for on-site marking

What types of electrical work is this best suited for?

This tape is well suited for general-purpose electrical insulation, splicing, and color-coding. Use it for indoor control wiring, outdoor service connections, appliance repairs, or bundling and identifying cables in panels and junction boxes.

• Splice and joint insulation for low- and medium-voltage wiring
• Weatherproofing outdoor connections and terminals
• Color-coding and identifying wire groups (black roll pictured)
• Temporary or long-term mechanical protection for cable assemblies

Who is this for: Professionals and home technicians who prioritize durable, weather-resistant electrical insulation in a compact package. If you need a trusted tape for field service calls, panel work, or outdoor wiring tasks, this 3M Scotch Super 33+ roll provides professional-grade performance with the convenience of portability and a bonus pen for quick marking.
