Best Crimping Tool For Heat Shrink Connectors

Disclaimer: All claims are strictly my personal opinion. As an Amazon Associate, I may earn from qualifying purchases.

A heat shrink involves creating a protective layer around wires, terminals or splices, and connections. A heat shrink is made of a substance that will shrink when heated to make a secure seal.

This process is not that easy to control with conventional tools like pliers and ratcheting crimpers. We need to use a proper crimping tool that will help make the job done efficiently.

These crimping tools also help to melt or fuse the heat shrink material.

Over the years, I’ve tried several crimpers, and none have met my expectations. A loose connection would cause erratic connections, or a total disconnect, as the connections would not be sealed properly.

Those with crimping capabilities that are more effective and of better quality are available. In addition, some are designed more ergonomically for better productivity.

See at Amazon!

Features at a glance
  • Suitable for wire sizes ranging from AWG 10 to AWG 22
  • Three crimping cavities are available
  • A 1-year warranty covers the product


If you’re looking for an all-rounder wire crimper, consider Haistronica, one of the smaller and relatively new brands for wire crimpers.

Wire crimpers from Haisstronica are quite comparable to other options in its class that are cost-effective. This wire crimper offers three crimping cavities in all.

In addition, these three crimping cavities provide decent compatibility between AWG 10 and AWG 22. Aside from the warranty, this wire crimper has a great build quality and comes with a one-year warranty.

Although solidly constructed, the heavyweight means the device cannot be easily taken with you.

A professional device like this one makes it simple to forge various types of heat shrink connections. Those shells with indentation can be crimped securely. The wire is firmly grasped by it.

Red, blue, and yellow color coding is used with each crimper tool. As a result, it is easier to identify.

Its shape makes it suitable for crimping the heat shrink terminals’ electrical connection, and it provides sufficient clearance to leave the heat shrink sleeves intact.

The crimper is also made out of thick steel and is very rigid, and doesn’t stretch in any way. With good surface finishing, the anvils were forged. This is the best and cheapest tool to crimp insulated terminals.

What we Like!
  • Sturdy construction and great styling
  • Multi-wire support
  • The crimping cavities are very easy to use
Things to Consider!
  • A bit heavier

2. Electroplated Steel Wire Crimper Tool for Heavy Duty

Features at a glance

  • Customer service that you can count on


Professional electricians should take it. Crimping electrical wires using this tool is possible. The wires can be forks, rings, sleeves, or butt connectors.

The material can be used to insulate Heat Shrink Terminals or for semi-insulated splices. In addition, by ratcheting, crimping can be performed faster and more efficiently.

The design of this Crimper tool makes it both practical and functional, making it a mechanic’s dream tool. Mechanics servicing automobiles, marines, avionics, and electrical appliances should have this tool.

Our favorite part about this product is its packaging; it’s packaged in a box that could also be used as a storage container. A crimping tool that ratchets completely closed for complete crimping.

In addition to supporting the three most common sizes of splicing and terminating hardware, the tool also accommodates other sizes.

This crimper also features a release lever that enables you to easily open a partially crimped piece of hardware without fully having to close the handles; this is a useful feature if you need to restart the crimp.

There is no spacer between the metal parts of the crimping die, unlike other common crimping tools.

By avoiding piercing the insulation on connectors, the crimp is much better. When finished, the connection is tight and professional looking. It takes more pressure compared to other ratcheting crimpers.

In addition, we appreciate the fact that the tool can be adjusted. Therefore, we highly recommend this tool; it is of excellent quality and will last you a long time.

What we Like!
  • An electroplated steel with a nickel finish
  • Ratcheting mechanism

Features at a glance
  • Total Crimping Range: AWG 10-20
  • The terminal is never damaged while being crimped
  • It is suitable for nearly all types of heat shrink connectors


Years ago, I would have loved to have these. Crimps are consistent every time. Additionally, the ratcheting function is convenient. This is a great tool when using heat-shrink wire connectors (such as those from Ticonn). This product is also ideal for use in auto & car stereos. Stabilizing and weatherproofing the connections is one of their best features.

The designers’ design this small tool to be used even with one hand and in a restricted space. Several jaws hold the solderless connectors firmly and lock them in place.

The quality of this product is very high. You won’t have to worry about this tool rusting. Besides the excellent coatings, the crimpers are well greased and very well assembled. The flat crimp that you get from these does not have a dimple.

With these crimpers, wiring is no longer an issue. The wire is crimped solidly and doesn’t slip any longer, meaning no more broken connectors.

In addition, this feature allows you to adjust the crimp pressure exactly to your needs. I definitely recommend it if you are looking to give a professional look to your wiring project.

There is no more tearing of the plastic off the connectors as with the other ones. Instead, it provides a professional appearance to the connector. That’s by far the easiest I’ve tried so far.

Upon ordering, I didn’t receive any instruction manual. It won’t be difficult to use; I will describe how to do it. Wire terminals must be inserted into the crimper in a certain way.

A wire can be inserted where the colored dots are located on your terminal. As far as adjusting it, I found that what the manufacturer had it set to was good.

When your crimped terminal is completed, the “FLAT” will appear at the location shown on the terminal. If you do a web search, you can also refer to the information available for the KLEIN TOOLS 3005CR tool since it is very similar.

What we Like!
  • It is easy to identify the respective holes on the jaws because they are colored.
  • The ratchet mechanism is adjustable for ease of use.
  • It is more comfortable to hold handles that have soft grips.
Things to Consider!

A ratcheting mechanism is used in the TICCONN hand crimper. Moreover, it has an automatic die crimping system that ensures rock-solid crimping every time.

As the handle is squeezed through a full ratcheting cycle, the wire connectors are crimped until they release automatically. Ratcheting the connector allows you to attach wires to the crimp while the connector is secured.

You can adjust the tool’s crimping height with its star wheel according to your crimping project. Crimper jaws can be positioned anywhere using a designated quick release lever.

I am more pleased than expected with the quality of this tool. It is an easy process to ratchet. The crimps are neat and tight. Everything is fine in this. Multiple sizes were crimped over a period of several hours. I think they’re a good fit. A good grip and easy adjustment make it a great tool.

There isn’t anything else on this site other than the profile for typical crimp connectors. Another view shows the profiles of the connectors with heat shrink tubing.

When working with tubing that tears, crimp from the opposite end.

In case the crimp fails to hold, move the fitting to the opposite jaw. There is no doubt that they are extremely heavy.

Buying a lighter set would be the best choice for me if I worked in a profession requiring them every day. However, I find them to be quite functional and affordable for my occasional needs.

What we Like!
  • This tool is more affordable than most others.
  • It provides a Precise Ratcheting Mechanism.

If they are used properly, they will not over crimp/crush the terminal. To ratchet the connector, hold it until it is fully crimped and then release it. They have a comfortable grip.

Chrome vanadium steel is used to make crimping pliers. There can be no doubt about the durability. Having an oxidized coating makes the jaws corrosion resistant and long lasting.

With high-precision jaws, the terminals won’t be damaged at any time during the precision crimping process. In addition, a rubber-wrapped gripper handle ensures a soft and comfortable grip.

Wires of 22-10 AWG can be secured and stabilized using the toothed fixture. However, after the crimping has been completed, it is difficult to drop and separate.

When a heat-shrinkable terminal is used for a long time, the hole will not break. As a result, heat-shrink tubing is not damaged by crimping. By eliminating breakage, the crimping process is one-time and precise.

The crimper jaws can be opened at any position because of a special quick release lever.

Ergonomically designed, non-skid handles enable users to grip the device firmly no matter what kind of weather conditions are present.

What we Like!
  • This is suitable for the majority of connectors and terminals that have been pre insulated.
  • Crimping range 22-10AWG.
