Hat Precisely Are Heat Shrink Butt Connectors

Heat Shrink butt connectors, in simple words, is a specifically designed connector meant to shrink to fit wherever it is applied after being subjected to heat. It can be put to a wide range if uses, and is specifically beneficial for regular maintenance and doing repairs.


You might not be aware of it, but if you utilize anything electronic, such as iPods, MPs players, and mobile phones, you have to contact with heat shrink connectors.

What is its basic use?

The heat Shrink butt connectors are designed to basically insulate wires from extreme heat. It is also utilized to seal and protect wiring in cable joints from dust and water, prevent any wiring it is utilized on from abrasions by wind, dirt, and general exposure. It is also utilized to harness bundles of wires together, and has been utilized to repair damage cables and wires.

What it is manufactured of?

Heat Shrink butt connectors can be made from any thermoplastic material, polyvinyl and polyolefin chloride are the most popular options in materials to make this type of plastic tubes, and other materials are frequently added during creation of the heat tube for extra abilities such as waterproofing.

Common Utilizations

Shrinkable tubes and trailer repair products and accessories can be utilized in various ways, from preventive maintenance to making electrical circuits. It is frequently utilized as a way to prevent stress and stain of electrical wiring generally caused by bending and flexing the wire at or near the connectors. Bending and flexing the wire connectors not only pose the stake of damaging the wires in the cable, it can also damage the surrounding insulation. Shrinkable tubes are terminals and connectors that are regularly exposed to the associated elements.

5 Factors That Determine A Good Deal On Heat Shrink Butt Connectors

Buying the butt connectors for wiring applications?

The “heat shrink” category fares better than any other in several aspects. For example, they create a perfect seal between the butt connector and the wire. Earlier, soldering was sought as the top technique to joining the wires, but with the advent of heat shrink butt connectors, the former is less used. Reason? The butt connectors don’t cause any extra installation or setup costs. Moreover, they are cheap, safe, easy-to-use and convenient.


Well, we paused the buying topic for some explanations. But, here we are again…

If you shop at normal brick-and-mortar stores, you may find a decent variety, but that wouldn’t fetch a good deal. Instead, you must shop online and buy electrical supplies and similar products.

The five factors that would determine a good deal online include:

1. Product Description. You shouldn’t buy what you don’t know. First, read the product description and know if it meets your requirements or not. Requirement as in, size, strength, resistance, rating, etc.

2. Minimum Order Quantity. You may or may not require a large quantity, but you’d want some. Therefore, see the minimum order quantity that you can place at the seller. Discounts/coupons may apply on large orders.

3. Reviews. Check reviews or feedback provided on various forums about the products and the seller. For example, a person buying 3m heat shrink butt connectors may provide his/her experience on its applications.

4. Prices. The price of butt connectors would vary at different online stores. For example, a 12-10 AWG butt connector may cost $0.66 apiece at one site and $0.34 at another. Therefore, check prices against other parameters.

5. Policies. As a buyer, you need to check the terms and conditions and policies of the seller. It would further help in getting a great deal.

Glue Lined Heat Shrink – Advantages And Applications

Adhesive lined heat shrink tubing, commonly known as glue lined tubing, has all the advantages of traditional heat shrink but with one other important feature; a layer of thermoplastic adhesive. Coupled with a hot-melt adhesive inner lining the tubing is made with Polyolefin outer tubing. This layer of glue enables the tubing to offer a better seal and adhesion.

The different properties inherent in glue lined heat shrink tubing along with heat shrink butt connectors make it better suited to certain applications and environments than the standard tubing.

Firstly, it is considerably thicker than normal heatshrink. Obviously it offers a secure and more permanent method of insulating heavier cables although this precludes it from being used in more precise applications.

This means as compared to the standard stuff it is far less flexible, and it won’t coil with the wire like smaller standard heatshrink because of this rigidity.

Glue lined heat shrink tubing with 3m heat shrink butt connectors is widely used in marine applications as it lends itself well to certain environments. It is ideal for sealing mechanical and electrical components and insulating against water and moisture, because of its superior sealant properties. It’s also ideal for effective moisture-resistant insulation of electrical connections and splices.

For instance, when repairing electrical equipment on a boat, a butt connector is often used. These connectors help maximize current flow and protect against corrosion but also use glue-lined tubing to seal out the water. And this sturdy tubing also has the added advantage of relieving some mechanical strain.

As well as the marine industry, adhesive lined heat shrink tubing is widely used in the automotive and electrical industries. Applications include general electrical insulation, mechanical protection and harness/cable bundling. The tubing can be supplied as a continuous product or can be cut into lengths and even printed.

5 Tips To Buying Heat Shrink Butt Connectors

While we all know why butt splice connectors are used, their purchase seems to become easier for all of us. However, that’s not easy.
