Product Information
About
【Waterproof & Sealed Protection】 Dual-wall construction with inner heat-activated adhesive melts to form a complete waterproof barrier. Perfect for marine, automotive, and outdoor applications where moisture, salt, and dust resistance is critical. Exceeds standard single-wall tubing protection.
【3:1 High Shrink Ratio - Maximum Versatility】 Shrinks to 1/3 of its original diameter (1/2" to approx. 1/6"), allowing one size to fit a wider range of connections. Ideal for irregular shapes and large wire-to-connector transitions, providing a tighter seal than 2:1 alternatives.
【Marine & Industrial Grade Durability】 UV-resistant polyolefin outer layer withstands harsh environments (-40°C to 125°C). VW-1 flame retardant certified, resistant to chemicals, oil, and abrasion. Made from eco-friendly, non-toxic materials.
【Professional Results Made Easy】 Pre-applied adhesive requires no additional glue. Simply slide over connection and apply heat with a heat gun for a factory-quality seal in seconds. 50-foot roll provides ample length for multiple projects.
【Trusted Applications】 Reliable solution for boat wiring, automotive harnesses, RV electrical systems, outdoor lighting, industrial controls, and DIY projects. Provides strain relief, insulation, and corrosion protection all in one.
