Heat Shrink Butt Wire Connector Kit

Key Features

  • Dual-Walled Waterproofing: Constructed with a rugged polyolefin outer tubing and a hot-melt adhesive inner lining that flows when heated, creating a 100% watertight, corrosion-resistant seal around the wire splice.
  • Seamless Copper Barrel: Features a thick, seamless tinned copper inner barrel that provides maximum current flow, prevents the wire from slipping out, and guarantees a strong, reliable crimp every time.
  • High Shrink Ratio: Utilizes an industry-standard 3:1 shrink ratio, allowing the tubing to tightly compress over a wide variety of wire insulation diameters for a secure, vibration-resistant grip.
  • Color-Coded Identification: Connectors are universally color-coded (Red, Blue, and Yellow) with standard wire gauge imprint markings directly on the tubing, making it easy to grab the exact size needed for your project.
  • Translucent Tubing: The semi-clear outer shell allows for visual inspection of the wire insertion and crimp placement before you apply heat, preventing blind, faulty connections.

Product Specifications & Included Components

  • Total Quantity: 200 Pieces.
  • White Connectors (20 Pcs): Fits Wire Sizes 26-22 AWG (Max Current: 15 A).

  • Yellow Connectors (20 Pcs): Fits Wire Sizes 12-10 AWG (Max Current: 48 A).
  • Material: Tinned Copper Core + Polyolefin (PE) Shrink Tubing.
  • Operating Temperature: -65°F to 255°F (-55°C to 125°C).

Universal Compatibility & Applications

These marine-grade butt connectors are the gold standard for creating permanent, weatherproof electrical splices in demanding environments:

  • Marine & Boating: Essential for bilge pumps, navigation lights, and trailer wiring exposed to salt spray and submersion.
  • Automotive & Off-Road: Perfect for under-hood wiring, LED light bars, and sensor repairs where heat, moisture, and vibration are constant.
  • Outdoor & Home: Landscape lighting, RV electrical systems, and outdoor water pump connections.

When to Use or Upgrade

  • Replacing Tape and Wire Nuts: Electrical tape leaves sticky residue and unravels over time, while standard twist-on wire nuts trap moisture and vibrate loose. Upgrade to heat shrink connectors for permanent, professional repairs.
  • Corrosion Prevention: If you are wiring anything that lives outside or near water, standard nylon crimp connectors will eventually turn green with copper oxidation and fail. The adhesive seal in these prevents moisture intrusion entirely.

Installation & Wiring Tips

  • Proper Stripping: Strip roughly 1/3 of an inch of insulation off your wires. Ensure the bare wire ends do not overlap the inner metal barrel to prevent them from poking through the heat shrink tubing when crimped.
  • Use the Right Tool (PRO TIP): Do not use pliers to smash the barrel. Use a dedicated ratcheting wire crimper with a die specifically designed for heat shrink connectors (usually marked with a red/blue/yellow dot or "Heat Shrink"). This prevents puncturing the plastic jacket during the crimp.
  • Apply Even Heat: Use a dedicated heat gun, starting from the center of the connector and rotating it to distribute the heat evenly outwards. This pushes air bubbles out of the ends and melts the internal adhesive evenly.
  • Avoid Open Flames: While a lighter can work in a pinch, it often burns the plastic tubing and leaves a weak, brittle seal covered in black soot. Stick to a heat gun for reliable, factory-looking results.
  • Allow to Cool: Let the connector cool for 30 to 60 seconds after heating before tugging on the wires, allowing the internal hot melt glue to fully solidify and lock the connection.

Received Burst Water Flosser, that never worked. Found out too late.
Color: Rose Gold
Ordered this item on recommendation of my dental hygenist, then needed a tooth pulled and was starting the dental implant process so was told I couldn't use it for awhile. The process took another 1 & 1/2 years. After the final crown I was told to use a waterpik. I went to use this, was unable to charge it, may have been missing a part, tried a matching plug. It wouldn't charge or turn on. Too late to return, so I'm out a good chunk of money in exchange for junk, something that never worked. I wonder if someone had returned a defective one as it had a dark finger smudge where it turns on, which I couldn't wash off. The tips were in a new package. Very disappointed.

Perfect in every way!
Color: Rose Gold
This flosser is perfection. It starts with the packaging and presentation. The flosser itself is beautiful (I got the rose gold), a nice sleek design that looks great on the bathroom counter. It is well constructed; I have tried the cheaper versions of these flossers and they all have a hose that hangs in the water reservoir that eventually gets clogged and stops working. Save your money and go for this one. Another great feature is how LONG it holds the charge. I am one month in and it is still operating on the initial charge at full strength. This makes it ideal for travel, along with the adorable travel bag included in the package. I also appreciate not having the wires cluttering up my counter space, which was the case with the cheaper models that have to be charged after each use. So far the company has been great to deal with - it comes with a 1 year warranty, which is easy to sign up for on their website. After the one year, you can subscribe to automatic tip replacements (each 6 months) and that will extend the warranty.

Be sure to still floss
Color: Rose Gold
This is a great product. However, make sure you still floss. I used the water flosser only between my dental cleanings and I ended up with a lot of tarter that had to be scraped off. I was told that I should continue using string floss as plaque is sticky and a water flosser can leave some behind. The hygienist compared it to expecting rain clean your car well. I still give it 5 stars as it remove particles from between my teeth that floss leaves behind. Also, my teeth were nearly perfectly clean during my last visit to the dentist. There was virtually no tarter as I followed her recommendation to both string and water floss.

They leak and the don’t last, but they’re sleek.
Color: Black
I love the shape of this flosser, that aspect is perfect. That’s the reason I’ve bought (3) over the years. But unfortunately, I’m done. Looking for a new gig. Every single one has leaked water. I just dealt with it. But the year and a half life they last is the deal breaker. Buy the insurance. You will use it. They simply do not last forever.

Perfect for home or traveling
Color: White
This is my second water floss, product, and by far the best. Yes, the water reservoir is not as large as some of the others, but it is perfectly adequate. Easy to use, has three different settings, that are easy to change. Definitely enough power to get all the food out from between my teeth. I use this when I had braces, and I use it now with my retainer, so that my teeth are always clean. I like the design, and the fact that it doesn’t have a tube to suck the water. The charge lasts for an extended period of time and recharging is very quick. I can go two to three weeks, and it’s still got a good charge to it. Highly recommend.
