How thick is heat shrink tubing?
As heat shrinkable tubing is reduced in diameter, the wall thickness increases proportionally. To illustrate, heat shrinkable tubing specified as having a 1/2″ ID with a 0.025″ wall thickness is supplied with an internal diameter of no less than 0.500″ and a wall thickness of 0.012″.

What can I use instead of heat shrink tubing?
What are Some Alternative Solutions to Heat Shrink Tubing?
- Tape wrapping – Wrapping bundles of wires using tape to create a wire harness.
- Dip coating – Dipping components into a liquid compound that will adhere and solidify creating a layer of protection on the dipped items.
Can I use electrical tape instead of heat shrink tubing?
Electrical Tape. Heat Shrink Tubing Vs. A common misconception when determining the ideal method for wire bundling or insulation is that heat shrink tubing and electrical tape are virtually interchangeable for any application. …
What size heat shrink should I buy?
In general, it is recommended that the supplied inner diameter of the heat shrink tubing and the size of the object to be protected should not exceed a 40% ratio to allow for effective coverage.
How is heat shrink size measured?
To begin, flatten out the heat shrink. Measure the width of the flattened piece with a set of calipers, if you have one, and multiply that figure by 2. Divide this figure by 3.1416 (pi) and the result will be the diameter of your heat shrink tubing.
Is heat shrink waterproof?
Polyolefin Tubing is a variety of heat shrink tubing that is highly resistant to flame, highly flexible and has excellent chemical, physical and electrical properties. Dual Wall Polyolefin Tubing provides a permanent, waterproof environmental seal and meets military specifications.
Can I use a hair dryer for heat shrink tubing?
A hair dryer would not be able to produce enough heat to melt the solder and shrink the tubing. We recommend using a heat gun with these Wirefy heat shrink solder & seal connectors.
Is heat shrink necessary?
When used as a protective covering, heat shrink provides protection from abrasion, cutting, scuffing, and low impact situations. It’s able to be used with virtually any design of conductor. Heat shrink can also be used to create cable entry seals providing protection from the surrounding environment.
How strong is heat shrink?
Heat Shrink Wrap Typically it has a shrink ratio of 3:1 and provides a firm a seal resistant to moisture, chemicals and fungal contamination.
How much does heat shrink reduce?
It should be noted that heat shrink tubing also shrinks longitudinally by 5 – 7% when it is heated. Therefore, adjustments should be made when selecting the length.
What is heat shrink tubing and how is it used?
Heat-shrink tubing (or, commonly, heat shrink or heatshrink) is a shrinkable plastic tube used to insulate wires , providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical work.
How do you heat shrink tubing?
Steps Select the right tool for the size of the heat shrink tubing you want to expand. To stretch larger tubing, use a combination of two pliers to expand the tubing as shown in this illustration. Insert the tweezers or pliers into the tubing as far as possible. Pull the pliers apart slowly to open up the ends.
What size heat shrink?
Heat shrink tubing is available in three main types: single wall with a shrink ratio of 2 to 1, dual wall with a shrink ratio of 3 to 1, and Heavy Duty with a 3 to 1 shrink ratio. All of our tubing is made from durable polyolefin . Single wall heat shrink is our most popular tubing. It is available in sizes from 1/16 inch to 2 inches in diameter.
What is dual wall heat shrink?
Dual Wall Heat Shrink Tubing With Adhesive is excellent for protecting, insulating, and sealing electrical connections. Made from durable polyolefin which is flame retardant, flexible, an excellent insulator, and resistant to abrasion. Dual wall heat shrink has an thicker outer wall than standard heat shrink and also has a shrink ratio of 3 to 1.
