Organize Your Electric Circuit With the Best Heat Shrink Tubing

Last updated: 28 Feb 2023
Using electrical cable ties and tape can help with organizing your electrical wires and overall system. However, these two methods are not able to stand in comparison to heat shrink tubing. Not only is this product a versatile plastic coating that electricians and similar professionals can readily apply on cables and components for various uses, but it also aids in covering and organizing wire. Also, the adhesive in the heat shrink tubing is intended to melt uniformly and create a watertight finish. Using heat shrink to insulate wires is quite simple, but it is vital to determine a few tips to prevent unwanted errors. There are so many options that you might spend hours visiting from site to site and comparing them. We reviewed and compiled a list of the quality heat shrink tubings of 2023 to assist in selecting the most effective for you.

Finding Quality Heat Shrink Tubing: A Buyer's Guide

Selecting the ideal heat shrink tubing depends on your requirements. You must choose marine-grade tubing with water-resistant characteristics to install tubing in a water pump connection or watercraft. For electrical repairs on an RV, durable tubing that can endure prolonged vibration is ideal. They are available in many colors and sizes, facilitating circuit labeling. Also, some tubings have a length of up to four feet. Before selecting a suitable one, you must consider several variables. So let’s examine the factors to consider when selecting heat shrink tubing that allows you to build custom lengths that precisely meet your demands.

  • 1 How To Pick the Right Heat Shrink Tubing
  • 2 How To Use Heat Shrink Tubing

How To Pick the Right Heat Shrink Tubing

Diameter and length of the tube

You need to ask yourself, “Are the sizes of the heat shrink tubes sufficient to cover the terminals?” When you acquire this tubing to secure your wiring, you must ascertain the length of the terminals you need.

Shrinkage ratio

The next factor to consider is whether the shrink wrap diameter corresponds to the wire diameter you need to cover and whether it is flexible enough to allow me to bend the wire after installation. The market has three shrink ratios: 2:1, 3:1, and 4:1.

It is safe to select the 3:1, which shrinks to around one-third of its original size and can accommodate various wire dimensions. Although it is thinner than tubing with a 4:1 shrink ratio, it retains considerable flexibility to aid installation.

Pieces and hues by size

Does the box have sufficient pieces and colors to meet your needs? Consider this when working on several installations, especially when you need to name the connections. Occasionally, color is less significant when the circuit you are working on is already completely delineated. 

Specifications, including temperature

The next factor is to consider whether the product provides the safety features necessary for your installation and is suitable for interior and exterior use or exclusively for interior structures. When installing in exposed regions, you must pick tubes with several safety characteristics, such as oil-proofing, waterproofing, corrosion resistance, and more. Heat shrink tubings help protect electrical systems; thus, if they are not rated to survive the environment the wires are in, this could lead to future problems.

How To Use Heat Shrink Tubing

  • Begin by selecting the optimum size and shrink ratio for the tubing. Keep in mind that it must be across both its width and length. Before it is shrunk, it must cover the cable or components comfortably to provide a snug fit afterward.
  • If the size of the components it covers changes after application, check that the tubing has appropriate expandability by measuring its diameter after shrinking to its diameter before shrinking. Check the tube’s suggested heating temperature to prevent an uneven application or melt.
  • Using standard scissors, cut an appropriate length of tubing and lay or slide it over the points. Then you can easily heat shrink wrap. This may get accomplished with a heat shrink oven or a heat gun. The latter are specialized equipment for more precise and sophisticated heat application.
  • To reduce the risk of burns while using a gun, circulate the heat back and forth through the tubing and avoid becoming stationary. Continue until you securely wrap the item.

People Also Asked

Q: Can I cut a heat shrink tubing?

A: Yes. Most of the time, all you need to get an exact length of tubing is a pair of scissors and a ruler. For thicker tubing, you might need pliers or wire cutters. Do not try to cut the tubing in half lengthwise, as this will weaken it, making it less resistant to water, and could cause it to tear. Also, be sure to wear protective gloves while cutting to avoid injuries.

Q: Can I replace heat shrink tubing with electrical tape?

A: In some cases, this might work, but the electrical tape isn't as strong as heat shrink tubing and is more likely to lose its stickiness over time. So, you might have to check the electrical tape often to ensure it stays strong. Electrical tape is easy to use and doesn't take long to put on, but it doesn't protect as well against moisture, corrosion, or wear, so it's not a great option for places that are hard on things. Also, if you have pets they are able to chew more easily through the electrical tape in comparison to heat shrink tubing.

Q: How can I remove heat shrink tubing?

A: Locating the end of the heat-shrinkable tubing is the initial step. Using a blade, remove the tubing while maintaining the wire free from the electronic circuit. Then, grasp this with a thin plier; needle tip pliers are ideal — and slowly pull away from the attachment. Ideally, this should be an easy process.
