Product Details
✓Excellent Shrink Ratio – Unshrunk diameter: 3/16 in (4.8 mm); shrinks down to 1/16 in (1.6 mm). The 3:1 shrink ratio ensures a snug fit, outperforming standard 2:1 heat shrink tubing for a more secure connection
✓Secure & Waterproof Seal – Features a dual-wall design with adhesive lining. When heated, the shrink tubing inner glue melts and adheres tightly to the surface, creating a waterproof, durable, and long-lasting insulation layer. Note: The reel may display 33ft due to a packaging mislabel. The actual tubing length is 50 ft as listed
✓High-Quality Material – Heat Shrink Tubing made from premium polyolefin, this tubing is tough, flexible, and resistant to wear, corrosion, and aging. It provides strong insulation and won’t easily crack or break
✓Safe & Eco-Friendly – RoHS compliant, free from heavy metals and hazardous substances. Non-toxic and environmentally friendly—safe for both your body and the environment
✓Note: To ensure you order the correct size of heat shrink tubing, please confirm the exact diameter you need before purchasing. 3/16 in (4.8 mm) refers to the diameter of the round tubing before shrinking
✓Versatile Applications – Heat Shrink Tube ideal for electrical wiring, marine projects, solder joint protection, corrosion prevention, and component insulation. Also great for headphone or charging cable repairs
