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.

Great quality
Size: 6 Ounce (Pack of 1)
Thinksport SPF 50+ Mineral Sunscreen with Zinc is a reliable, high‑protection option that feels lightweight and non‑greasy on the skin. It applies smoothly without leaving too much white cast for everyday use, and I love that it’s mineral‑based with zinc for strong UVA/UVB defense. Great for active days outdoors. Highly recommend for sensitive skin and safe sun coverage!

Brown skin approved!
Size: 6 Ounce (Pack of 1), Size: 6 Ounce (Pack of 1)
Does not leave a white cast, feels very light on the skin. Scanned on Yuka and was a 86/100 green zone! It’s so hard to find a sunscreen that isn’t trying to poison you, scanned all the sunscreen at Walmart and were rated a 1/100 through 6/100. Which brought me to Amazon. Thinksport has my vote on goodness and healthiness, would buy again!

My favorite... And I'm picky.
Size: 3 Ounce (Pack of 1)
I've become a little obsessed with sunscreen over the last past 5 years. I have olive skin and developed melasma after my first pregnancy. I learned the hard way that chemical sunscreens don't help if you have melasma - and they actually make the dark spots even worse. Also the active ingredients in chemical sunscreens (like Oxybenzone and Octinoxate) are absorbed by your skin, and may cause allergies, hormonal imbalance and be toxic overtime. After learning that, I started wearing only mineral sunscreen (active ingredient is zinc and/or titanium dioxide). These are not absorbed and works by creating a physical barrier that reflects the sun (some studies suggest that some nanoparticles of zinc may be absorbed by your skin, so to be really, really safe you should look for non-nano particles). After trying a few brands, I realized the sunscreens with only zinc in their formulas worked better than the blends with titanium dioxide, but this is just my personal preference I guess. And the higher the percentage of zinc, the better. Most pure mineral sunscreens out there are 10-ish % zinc, SPF 30, 40 min water resistant - which is ok. Thinksport goes beyond that: It's 20% non-nano zinc, SPF 50+, 80 min water resistant. It really can't get any better than that! The lotion is not extremely thick when compared to other sunscreens I've tried and I find it pretty easy to apply. As every zinc sunscreen, it does leave a little fine white cast, but honestly Thinksport is not bad at all! It smells nice, lightly citrusy - and the smell vanishes soon. And, it's not overpriced. Best I've tried so far.

Works but will Dry Out Your Skin
Size: 6 Ounce (Pack of 1)
I am a swim instructor at an outdoor pool and this stuff DOES work. I can apply it at the beginning of a 5 hour shift and while I have experienced light tanning it has protected against burning completely without reapplication. The white cast is significant though I don't mind it aesthetically, I know its there for protection . It does rub off on things though so consider yourself warned. Major Con: it is incredibly drying, and the soap needed to scrub it off is A LOT. That coupled with chlorine is a lot for my skin . Still on my sunscreen journey.

This book was amazing!
Format: Kindle
I absolutely loved this book! Avery and Knox were beyond perfect for each other. Rebecca Jenshak did such an incredible writing this book and these characters. The brothers relationships in this family is wonderful. Everyone steps up to help take care of each other and it is heart warming. This book had low angst which I loved! I am really enjoying the start to this series and I cant wait to read the next book! The duet audiobook was incredible! Erin Mallon and Teddy Hamiliton did a fantastic job bringing this book and these characters to life! I highly recommend this book, audiobook, and series!
