Visit the Store Who We Are Wirefy is a small USA-owned and operated business. We offer top-quality electrical connectors, crimping tools, heat shrink tubing and electrical wires at reasonable prices. Wirefy empowers electricians and DIY lovers to make professional electrical connections through quality products and education. We've got you covered on your wiring project. We craft electrical connectors from thick, pure copper for strong crimps and max current flow. Tin coating protects against corrosion. Our terminals are fitting everyones needs. Our crimping tools come with high-precision crimping dies designed specifically for every terminal type. Our tools ensure consistent, effortless and rock-solid crimps. Go for 3:1 or 4:1 shrink ratio. This ensures a tighter seal. Make sure it has adhesive lining for protection against dust and water. ? Improved temperature resistance, tear and abrasion resistance and long-term performance. When heat is applied, adhesive comes out and seals the connection, creating a resistant insulation. Recovers to 1/3 of its diameter, and makes a tight seal. No air gaps between the wire and tubing. Our heat shrink tubing comes in kits as well as rolls. We offer a great variety of sizes and colors. Use with battery lugs in automotive projects. Make safe and secure connections in seconds. Seal your quick disconnect connections to make them resistant in motorcycle and other projects. Repair your charger and ensure long-term performance in seconds. Easy to use for everyone. Make resistant insulation on your ropes, shoelace ends and mountaineering gear. 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. 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 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. 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). 50 FT 180 PCS 190 PCS 3:1 3:1 4:1 3/32" - 2" 3/32" - 3/4" 1/4" - 3/4"

Key Features

• ✅ 3:1 SHRINK RATIO - Recovers to 1/3 of its original diameter, and makes a tight seal. Eliminates the problem of 2:1 tubing not shrinking tight enough.
• ✅ GLUE INSIDE - When heat is applied, adhesive comes out and seals the connection, creating resistant and long-lasting insulation.
• ✅ VARIETY OF SIZES - We have included larger diameter heat shrink tubing ranging from 1/8" to 1". Shrink tubing is precut to 1.75 inches.
• ✅ EASY TO USE - Simply slide heat shrink tube over your connection point and apply heat. Professional connections made in seconds.
• ✅ DUAL WALL TUBING - Outer wall provides abrasion resistance. Inner wall creates resistant seal and strain relief.
