Heat Shrink Tubing Kit – 568 Pc 4:1 Adhesive Marine Grade Assortment

-- THIS PRODUCT CONTAINS 568 SHRINK TUBES PER PACK --

This 568-piece heat shrink tubing kit delivers premium-grade protection and insulation for electrical and mechanical applications. Featuring a 4:1 shrink ratio, each tube can shrink to one-quarter its original diameter, ensuring a snug, secure fit on wires, terminals, and components. The internal adhesive lining melts during shrinkage to form a moisture-resistant, vibration-proof, and airtight seal.

Pre-cut to a uniform 2.2" length and sorted into seven commonly used diameters (ranging from 3/32" to 3/4"), these marine-grade sleeves are ideal for professional and DIY applications. The polyolefin outer layer offers excellent flame retardance, abrasion resistance, and high-temperature tolerance—making this a go-to solution for automotive wiring, marine installations, electronics, and more.
