• 3:1 SHRINK RATIO: 3:1 heat shrink ratio and will shrink to the original 1/3,and makes a tight seal. Eliminates the problem of 2:1 tubing not shrinking tight enough.Package: 1 pcs black 5/8 inch(15mm) heat shrink tubing roll, total length: 5 feet
• GOOD TIGHTNESS:Glue inside,When heat is applied, adhesive comes out and seals the connection.Dual wall adhesive heat shrink tube has the advantages of good electrical insulation, good sealing and high temperature resistance.
• DUAL WALL TUBING - Provides enhanced protection from wear and tear. The outer wall provides abrasion resistance. The inner wall creates a waterproof seal and strain relief
• EASY TO USE:Slide the heat shrink tube over your connection point and apply heat. Make professional insulated connections in seconds.
• WIDELY USE - Our heat shrink tubing are widely used in wire connection, rust prevention and corrosion protection of solder joints, protection and insulation processing of wire end, wiring harness and electronic components, and audio and electrical DIY. Fitness equipment parts and steel structure surface protection and so on.

Heat Activated Adhesive Lining

This is a waterproof shrink tubing with an internal adhesive layer. When heat is applied, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When cooled down, it forms a rigid seal. Heat-activated glue strongly adheres to wires, terminals, or any other surfaces. When adhesive flows, it pushes the air out and fills gaps between the wire and the tubing, making the connection waterproof. For best results, we recommend using a heat gun.

Dual Wall Shrink Tubing

Dual wall marine grade heat shrink tubing provides better rigidity and abrasion resistance. Dual wall tubing design has the increased ability to withstand wear and tear. This wire heat shrink tubing is flame retardant.
