Features:

  • Polyamide Hot-melt Adhesive
  • EASY IDENTIFICATION - Different Color coded tubing with wire gauge imprint provides easy identification. Measure your wire, and easily choose the right connector by looking at wire gauge imprint on polyolefin tubing.
  • EXCELLENT WIRE CONTACT - copper barrel provides increased current flow, decrease voltage drop, preventing wiring failures and reducing equipment downtime. Thick barrel ensures strong crimp every time - your wire will never slip out of the connector
  • WATERPROOF - Dual-walled Design, Polyolefin Tubing in Outside and Hot Melt Adhesive in Inside. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation. Dual walled tubing ensures waterproof seal and prevents wire corrosion
  • DURABILITY - The terminal barrel is created from one seamless piece of copper that eliminates the problem of the barrel opening. Translucent heat shrink tubing provides high tensile strength as well as resistance to stretch and mechanical damage
  • INSULATED and WATERPROOF MARINE AUTOMOTIVE TERMINALS - Whether you are working on your boat, vehicle, home or scientific project, our Heat Shrink Butt connectors will ensure strong crimps, increased current flow and waterproof connections every times
Great affordable option

No need to waste money on expensive name brand connectors. High quality, good gripping, shrinks well. The sorted holding container is nice and compact. I do automotive wiring professionally and these are a great go to for quick repairs that do not require soldering.

Works very well.

This is the easiest and most durable way to keep connectors from corroding in wet environments. I use them for all my outside and some inside application. It completely protects the connection from any environment.

Top notch butt connectors

Im very happy with these butt connectors. These heat shrink connectors also have the glue that melts which with the shrinking action gives you a great waterproof seal on your connections, some heat shrink connectors don’t have that feature. They work great. I will purchase these again when the time comes.

I use these all the time. The crimps are ...

I use these all the time. The crimps are a little brittle but people often wrench down on crimps too much anyways. These seem to be doing the job. If you get a little blast lighter they shrink cleanly without burning.

like 120v to 600v or 12v DC

heat shrink works well.just dont used to much heat.please pay the $24.00 and get the kipper tool with it.11477 ratcheting wire crimper you will thank me lather .connectors can be used on almost ever elec job. like 120v to 600v or 12v DC .cars / boats /trucks /mowers / and at home I keep mind in the work truck all the time and i uses them alot.

Fully sealed butt connector

These butt connectors are really a hidden gem. Crimp them onto the wire then take a torch to them and watch them fully seal to the coating on the wire. Eliminates the need for heat shrink tubing. I wish I would of had these for the last 30 years.

Heat Shrink Connectors

If you want top quality connectors that don't brake your wallet, these are the ones for you. I live next to the ocean were corrosion is a huge problem with outdoor wiring. The seal these provide is better than any I've used in the past, just make sure you use the correct one for the size wire you're working with. Would but these again in a New York minute!

3 Sizes of Electrical Connectors:Red for 22-18,, Blue for 16 - 14, Yellow 10 - 12 AWG that offer Waterproof connetotions.

These Connectors are 3 Different Colorcoded tubing with wire gauge imprint provideing easy identification. Red for 22-18 AWg , Blue for 16 - 14 AWg and Yellow for 10 - 12 AWG Just determine wire AWG , and easily choose the right connector by looking at wire gauge imprint on polyolefin tubing The copper barrel is crimped using a pair of crimpers you need to buy seperatly that often have the same color coding on them to crimp the tube to secure the wire. Has a Dual-walled Design, Polyolefin Tubing in Outside and Hot Melt Adhesive in Inside. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation. Dual walled tubing ensures waterproof seal and prevents wire corrosion and a solid tight connection. The case the connectors come in has individualized dividers so you can set it up how you want , I created a space to hold a lighter for heat shinking the connectors. Case is sturdy, has Strong hinges so it is long lasting. I have included some pictures of the process of using one of the connectors.

Worth every penny.

They hold tight and are probably the best but connectors I have ever used. I love the fact they have this hot glue stuff on the inside of the heatshrink. Makes it that much more water proof and secure. Tried a stress test using 16 gauge wire, every time the wire would break before the connection. Highest I could go before my 16 gauge wire broke was 54lbs, and the connector looks just as it did when I installed it. I'm a hardwire and solder type of guy, but I trust this better than some of my solders just beacsue of how water tight the connectors apear. The glue makes all the difference. Edit: another benefit, broke a hole in one with my crimping tools, normal connectors you would have to cut off and replace, these, the glue on the inside sealed the hole. Like it's sealed good enough, I'm not even worried about it. Can I make this 6 stars?

Quality Connectors

I used these crimp connectors when I changed the tail lights on my boat trailer to LED lights. The internal crimping material holds onto the wires well, and the shrink tubing shrank up nicely when heat from a lighter was applied. I expect them to remain water-tight and to keep a good connection for quite some time! A nice upgrade from the regular old barrel connectors the trailer came equipped with.
