508Pcs Black Heat Shrinkable Tube Set, Solder Seal Wire Connectors, Waterproof Solder Wire Connectors Heat-shrink Butt Connectors Wire Terminal for Marine, Watercraft, Electronics, Vehicles

Product 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, the adhesive comes out and seals the connection, creating waterproof and long-lasting insulation.
VARIETY OF SIZES: We have included 7 most commonly used diameters ranging from 2.0mm to 13.0mm.
EASY TO USE: Simply slide the heat shrink tube over your connection point and apply heat. Professional connections made in seconds.
DUAL WALL TUBING: Outer wall provides abrasion resistance. The inner wall creates a waterproof seal and strain relief.

Q1: What is the shrinkage ratio of this heat shrink tubing, and why is it beneficial?
A1: This heat shrink tubing has a 3:1 shrink ratio, meaning it recovers to one-third of its original diameter. This ensures a tight seal, eliminating issues that may arise with 2:1 tubing not shrinking tightly enough.

Q2: How does the adhesive inside the tubing work?
A2: The tubing contains glue inside that activates when heat is applied. As the tubing shrinks, the adhesive comes out, sealing the connection to create waterproof and long-lasting insulation.

Q3: What sizes are included in this heat shrink tubing kit?
A3: The kit includes 7 commonly used diameters, ranging from 2.0mm to 13.0mm, catering to a wide range of applications.

Q4: How easy is it to use this heat shrink tubing?
A4: It is very easy to use. Simply slide the heat shrink tube over your connection point and apply heat. This creates professional connections in seconds.

Q5: What materials and properties does this heat shrink tubing have?
A5: The tubing is made from polyolefin material, providing both abrasion resistance and a waterproof seal. It has a minimum shrinkage temperature of +70℃ and a full shrinkage temperature of up to +110℃. It can operate in temperatures ranging from -55℃ to +125℃, has a tensile strength of 10.4 Mpa, and a dielectric strength of 15 kV/mm. The tubing is flame retardant, UL approved, and manufactured to ISO9001 specifications.
