🔧 2:1 Black Polyolefin Heat Shrink Tubing – 30ft (10M) , Choose Your Size

Professional-grade heat shrink tubing, sold by the spool. Each order gets you a full 30 feet (10 meters) of continuous black polyolefin tubing in your selected diameter — from precision 1mm electronics work up to heavy 12mm cable bundling. Select the exact size you need from the dropdown above.

Why buy a full 30ft spool? Most "sample packs" give you a few inches of each size — barely enough for one job. Our 30ft spools give you real working length for multiple splices, production runs, or keeping on hand in your service van. Cut only what you need, save the rest for the next job.

Pick a supplied ID roughly 20–30% larger than the object you're covering (wire + connector + insulation).
After heating, the tubing shrinks to ~50% for a tight, professional seal.
When in doubt, size up — you can always double-layer for extra thickness and strain relief.

⚡ Key Advantages

30ft continuous length — no joints, no short off-cuts, enough for dozens of splices per spool.
Flexible after shrinking — stays pliable, resists abrasion and solvents.
Clean professional finish — black color, tight recovery, no messy electrical tape.
Fast application — heat gun, hot air tool, or lighter in a pinch.
UV resistant — black formulation holds up to light exposure.

🛠️ Typical Applications

Electrical: Wire splice insulation, terminal protection, harness bundling
Automotive: Trailer wiring, sensor leads, under-hood repairs
Marine: Electronics cable protection, corrosion prevention
DIY & Hobby: Cable repair, RC builds, drone wiring, headphone fixes
Service / Production: Production line wire management, field service vans, workshop stock

⚠️ Important Notes

This is single-wall polyolefin — for waterproof sealing, use adhesive-lined (dual-wall) heat shrink.
Not for continuous immersion or high-pressure environments.
California Prop 65 warning applies — see listing images for details.
Each spool is a single continuous length — no splices, no pieced-together sections.
