There are a lot of features to keep in mind while buying. However, here are some basic features to look out for. These simple steps will guarantee the best automotive wire connectors.

 The buyer’s guide will be of great help, especially for beginners. 

  • It should be resistant to water:

The correct automotive wire connectors will always be waterproof. Now, this might seem simple, but not all products offer this feature. A waterproof wire will not only last longer, but it will protect the cables.

Generally, it should protect the wire from any damaging environmental aspects.

  • It should be easy to use:

Generally, using wire connectors is a simple process. Even beginners can use it after reading the manual.

It will require a wire, a connector, a crimper, and a heat gun. It does not require any other complicated steps.

Thus, always go for automotive wire connectors that are easy to use. Why choose sophisticated over easy?

  • It should be copper plated:

Copper is the best conductor of electricity. Thus, look for wire connectors that use copper.

It not only protects from short circuits but ensures that the crimp is tight around the wires. Plus, it is resistant to corrosion.

  • It should have wire gauge imprints:

Automotive wire connectors consist of an assortment of various sizes. It makes identifying a specific size difficult.

Thus, always buy wire connectors that have gauge imprints on it. The print mentions the size of the connector, which makes it easy for users to differentiate. Plus, it is also available in various colors. It makes it easy to separate and distinguish the different types.

  • Always compare the price of products:

Many have the concept that the most expensive is the best. However, a costly automotive wire connector does not mean that it is the best. Many fair priced wire connectors give the same or even better result than expensive ones.

Thus, always compare the price of products before buying. Do not always settle for the expensive one.

With the basics of what an automotive wire connector is and how to buy one covered. Below are some of the best automotive wire connectors.

Frequently Asked Questions Section

Is Polyolefin Tubes a better choice than other products in the market?

Heat shrink tubings are tubes that shrink when heated. It needs to be heated because the heat activates the adhesive material inside the tube. What it does is the adhesive material secures the cable. Thus, the heat shrink tube and wire become joins to become one.

Polyolefin is a flame retardant material. It is known for its electrical and physical properties.

The Polyolefin tube is also UL recognized.

Sometimes, it is known as Automotive Heat Shrink Tubing for its extensive use in automotive applications. Please, note that heat shrink tubes are available in different styles.

Thus, Polyolefin shrink tubes are a popular choice in comparison to other products.

Is crimping needed to use a solder seal connector?

Solder seal connectors are a different type of connector. It does not need crimping, unlike most heat shrink connectors.

The process requires the user to slide the wire into the connector. Then, join the wires by twisting it. A unique feature of a solder seal is the tube is entirely transparent. Thus, it allows the user to position the cable right in the middle of the solder ring.

Then by using a heat gun, heat the tube. What this does is melt the solder ring and join the wires. Plus, activate the adhesive that will slowly shrink, making the seal waterproof and dustproof.

Those are the only steps required for a solder seal connector.

What standards to check while choosing automotive wire connectors?

There are a lot of standards to check while deciding for a product. These standards are essential because it ensures that every automotive wire is of high quality and safety. Some of the standards and certifications to look out for include:

  • Underwriters Laboratories (UL)
  • The CE mark.
  • The Restriction of Hazardous Substances Directive (RoHS) Certification.
  • The CSA registered mark.

Thus, checking these standards and certifications act as a precautionary measure. It ensures that every product the user buys is of the highest quality.

What difference does the heat shrink ratio make? Can I use any heat shrink tube without considering the shrink ratio?

Most manufacturers mention the heat shrink ratio in the description. The ratio states the size of the heat shrink tube before and after it is shrunk.

Some of the most common heat shrink ratios consist of:

  • 4:1 – The heat shrink connector will be four times the size of its shrunken form.
  • 3:1- The heat shrink tube will reduce to one-third of the original size once heated.
  • 2:1- The original size will be twice as large as its shrunken form.

For instance, imagine trying to put a thick wire into a 2:1 shrink ratio heat tube. The cable will not fit inside the connector.

Are the automotive wire connectors waterproof?

Yes, the wire connectors are waterproof. It is so because of automobiles’ exposure to liquids; thus, the wire connectors have to be waterproof.
