Heat Activated Adhesive RESISTANT CONNECTIONS When heat is applied, adhesive comes out and seals the connection, creating a resistant insulation. Secure Seal TIGHTER WIRE GRIP Recovers to 1/3 of its diameter, and makes a tight seal. No air gaps between the wire and tubing. Large Variety of Options PICK THE TUBING YOU NEED Our heat shrink tubing comes in kits as well as rolls. We offer a great variety of sizes and colors. VERSATILE HEAT SHRINK TUBING BATTERY CABLES Use with battery lugs in automotive projects. Make safe and secure connections in seconds. SEALING CONNECTIONS Seal your quick disconnect connections to make them resistant in motorcycle and other projects. DAMAGED CHARGERS Repair your charger and ensure long-term performance in seconds. Easy to use for everyone. ROPE ENDS Make resistant insulation on your ropes, shoelace ends and mountaineering gear. Super Versatile Heat Shrink Tubing Are you looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief? Wirefy heat shrink tubing is an easy to use solution that can be used in automotive, hobby RC, and home electrical wiring projects. When heat is applied, this wire shrink wrap tubing will recover to a 1/3 of its original diameter. Its high recovery ratio makes it possible to repair most damaged cable jackets without removing connectors. Therefore, 3:1 shrink ratio tubing can be used in significantly more applications compared to 2:1 shrink ratio tubing. Additionally, 3:1 heat-shrink tubing shrinks around wires and terminals more tightly, eliminating any air gaps. Heat Activated Adhesive Lining This is a resistant shrink tubing with the 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 any gaps between the wire and the tubing, which makes the connection resistant. For best results we recommend using a heat gun. Dual Wall Shrink Tubing Dual wall heat shrink tubing provides better rigidity and abrasion resistance. Dual wall tubing design has the increased ability to stand up to wear and tear. This wire heat shrink tubing is perfect for everyone. This industrial grade heat shrinkable tubing is compliant with all relevant electrical standards such as: SGS, RoHS, Reach, and ISO9001. Our Collection of Heat Shrink Tubing Wirefy assorted heat shrink tubing comes in kits as well as 50 Ft rolls. We offer a great variety of sizes (3/32” to 2”) and colors (black, red, white, blue, clear).
