Heat Shrink Tubing with Adhesive Insulated Wire Wrap Marine Grade 3:1 Ratio Kits
11.99 USD
Free Dual-Wall Polyolefin Heat Shrinkable Tubing
Wall Type: DUAL-WALL (Inner wall of "hot melt adhesive" to encapsulate and protect your wires!)
Sized by: ID (Inner Diameter)
Shrink Ratio: 4 to 1
- This premium tubing has an inner wall of adhesive/glue which melts when heated to encapsulate your wire and protect it from the elements
Uncut tubing or longer lengths are almost always available upon request! Just contact us!
When choosing sizes, make sure you are thinking in terms of DIAMETER. Diameter is the measure of a round object, not flat. Larger sizes may be flat prior to usage, but they are still ALWAYS sized by ID (inner diameter). Refer to the chart/diagram in the additional photos for further of premium cross-linked polyolefin, a robust and versatile material with excellent properties and durability
4 to 1 shrink ratio; will shrink to ONE QUARTER of the nominal (named) diameter. For example, the 1 inch ID tube shrinks to an inner diameter of 1/4"
The named diameter is the size BEFORE shrinking. The diameter will shrink to ONE FOURTH of the named size.
Dual-wall adhesive-lined; when heated, the inner glue-lining will melt and seal your wires to protect them
If you don't need the "hot melt adhesive" then you can buy single-wall tubing for a much cheaper price. I posted links to single-wall tubing above 👆
The tubing is sized by ID (inner diameter). Diameter is the measure of a ROUND shape, not flat.
COSMETICS: The tubing has a quality matte finish, not a cheap slick/shiny appearance like PVC tubes! There is no text printed on ANY of this tubing!
RECOMMENDED EQUIPMENT:
"Heat gun", "task oven", or "tubing torch" to shrink the tubing at 90°C ~ 110°Celsius
Do not overheat the tubing, you can compromise it! Do not use tubing which has been overheated!
Work in a non-flammable and well-ventilated workspace
Always use safety gloves, protective eyewear, and a respiratory mask when heating not perform repairs of electrical/electronic components unless you are a qualified, experienced, and knowledgeable professional. Performing repairs can be very dangerous. Don't do something stupid! Seek professional assistance/advice!
The tubing, adhesive, and items you are working with can get very hot! Be careful not to burn yourself - avoid touching heated objects/materials!
Heat-resistant gloves, protective eyewear, and respiratory mask are all recommended. Work in a well-ventilated area and non-flammable workspace. Clear your surroundings to avoid accidents! This includes children and pets!
Read and obey all safety instructions for operation of the heat source you choose to utilize when heating the tubing. "Heat guns" or specialized "task ovens" are recommended. Do not exceed 110 degrees Celsius when shrinking the tubing to avoid burning/degrading the tubing! Hair driers do not get hot enough to shrink most tubes, however they may be useful for tiny sizes. Torch/flame is not recommended as you may burn/damage the tubing.
While heated, the tubing is in a softened state until it cools, and thus may be easily damaged. Avoid stretching the tubing until it cools and firms up.
USAGE INSTRUCTIONS:
Read safety guidelines
Prepare equipment and work area
Slide tubing over wire
Apply heat to tubing to reach 90°C to 110°Celsius
Allow tubing and wire to cool
HANDY TIP:
The tubing is sized by ID (inner diameter). If you only know the flat width of the tube size you need (measuring across a flattened tube), but aren't sure what ID you should choose, you can quickly approximate diameter by dividing by 1.6! For example: If you need a tube that is 3 inches wide when flattened, you would divide 3" by 1.6, which equals 1.875". That means you should order the 2" ID tube
