Heat activated adhesive provides additional protection against strain, abrasion and vibration. Resistant to abrasion, stretch and vibration Heat activated adhesive Greater tensile strength All materials are heat resistant Wirefy is offering the most versatile electrical connectors kits with heat shrink technology on the market. In our electrical connector assortments we’ve included an extensive selection of the most common terminal types: butt connectors, rings, forks, hooks, male/female spade terminals. We offer each connector type in 3 industry standard sizes: red (22-16 AWG), blue (16-14 AWG) and yellow (12-10 AWG). Brazed terminal barrels for strong crimps Pure copper terminals for maximum current flow All connectors are easy to crimp and will not split Dual-wall heat shrink tubing protects the connection Low temperature heat shrink tubing recovery ensures no wire damage Color-coded with wire gauge imprint: easy to pick the right connector size Heat shrink connectors are super easy to use Convenient storage case for quick access FEATURES BRAZED SEAM BARREL Doesn't split when crimped Ensures rock solid crimps Wire will not pull out PURE TINNED COPPER Increased current flow No voltage drop Protection against corrosion THICK COPPER TERMINALS 1.0mm for 12-10 AWG 0.8mm for 16-14 AWG 0.7mm for 22-16 AWG Electrical Connectors That Are Super Easy to Use Wirefy heat shrink connectors turn any electrical wiring job into a fast and highly efficient process. Simply crimp your terminal and apply heat. Professional grade electrical connections can be made in seconds. For best results we recommend using a heat gun. Pure Tinned Copper We manufacture our marine connectors from pure copper for maximum current flow and minimal voltage drop. The tin coating protects your electrical connections against corrosion. Brazed Terminal Barrels Our brazed seam connector barrels are superior to typical butted barrels because they do not split when you crimp them. Brazed seam terminal barrels ensure your crimp is rock solid, and the wire will not pull out. Advanced Heat Shrink Tubing Heat shrink tubing shrinks to 1/3 its original size, ensuring the tight and secure insulation for every connection. Heat activated adhesive creates impervious seal to salt water, oil, acids, dust and sunlight. These heat shrink terminals require lower amount of heat, which reduces the risk of melting the wire insulation.

The best crimps are done with a ... - A quality product. It has a dual wall plastic cover; the inner wall is glue and the outer wall shrinkable plastic. When heat is applied, the plastic shrinks (ratio 3:1) and the glue (polyolefin) melts to form a good seal. The best crimps are done with a ratcheting terminal crimper, which applies the correct pressure (see further below). There is a broad selection of crimps in the kit, both the type and the size (9 types in 3 sizes). A dual wall crimp saves space when that is scare, like on a boat or travelling remotely in a car. I take a selection of crimps in a smaller container to save even more space. The 540 piece kit has enough crimp terminals for most general purpose tasks around the boat or car. This is the best all round terminal kit I have purchased. There is a difference between a single wall and dual wall crimp, the glue in the dual wall gives a stiffer result with less movement, but it also improves the overall strength. If you an issue with vibration (like Outback Australia or Africa) a single wall crimp maybe better, as it reduces the damage caused by corrugations/vibrations by allowing more movement reducing the damaging effects of corrugations. Choose the best option for a given job. CRIMPING TIPS Some suggestions on getting good crimps: 1. Buy quality terminals like the Wirefy. 2. Purchase a good wire stripper like the IRWIN VISE-GRIP 2078300 Self-Adjusting Wire Stripper or the Klein Tools 11063W Katapult Wire Stripper. 3. Purchase a Ratcheting Terminal Crimper. If you want a variety of dye heads for different jobs look at the SG Tool Aid SGT18980 Ratcheting Terminal Crimping Kit. iwiss makes a range of specialist crimpers. 4. Strip the insulation from the wire to the correct length with the wire stripper (note how much quicker, easier and better quality the wire stripper is compared to a pair of pliers). 5. Match the Wirefy terminal to the wire thickness (important for good crimps). 6. Place the terminal in the correct dye in the crimping tool. I gently close the crimper to lock the dye onto the terminal but without compressing the terminal, then I insert the wire into the terminal and compress the crimping tool. 7. Using the correct size dye and placing the terminal correctly into the dye is important. 8. A ratcheting crimper applies the correct pressure to make a great crimp. 9. Use an electric/butane heat gun to shrink the plastic cover and melt the glue. I apply heat until I can see the crimp seal and a little glue comes out of the plastic cover. Wirefy terminals are translucent so you can see through the plastic to inspect the seal. 10. Let it cool. Job done. Test the crimp. 11. Common mistakes when crimping: a) not matching the wire size to the crimp terminal, b) not using the correct dye for a given terminal type, c) not correctly placing the crimp terminal correctly in the dye jaws. 12. Practice is important. Develop a good technique before using crimps in real life. I have cheap terminals and old wire and I practice to develop a good technique before doing a job for real. Test both single and dual wall terminals and see for yourself the differences in stiffness I discussed above. The initial cost of the tools can be expensive, but they will give you a life time of service. One job I did on my car, meant the tools paid for themselves. I wish I had brought them years ago! Buying the larger size kits like the 540 Wirefy saves money. I spilt the terminals between me and 2 friends – we all get a selection and a big cost saving. Buying terminals in small kits is very, very expensive. I have found more uses for the crimps than I originally thought. ## Features - WIREFY MOST VERSATILE CONNECTOR KIT - Ring, fork, hook, spade and butt splice heat shrink wire connectors are included in this multipurpose electrical connector kit.

Unfortunately, not all of these crimp connectors are completely waterproof / water resistance. The heat shrink material does not completely cover the electrical connection. That's the only reason why I gave it a 3. However, they are far better than the non-shrink types out there. I do a lot of trailer light repair on the side, {horse trailers, boat trailers, various farm equipment and etc}. Most of them get abuse due to the elements they are in. Most of the lighting issues is from corrosion in the connections in the wiring. It is tedious to use a non-shrink crimp with separate shrink material. Getting the right size is the headache. This is a major benefit with these connectors as the heat shrink and crimp connect are combine together, crimp n shrink. Cuts out half the time. There has been several good comments about the heat shrink binding to the wire's insulation. This will help with vibration on the connection point, preventing wire breakage. Overall, this is the better way to go and would recommend this to anyone !!! ## Frequently Bought Together - Wirefy Heat Shrink Crimp Connectors Kit - Heat Shrink Wire Connectors - Automotive Wire Connectors Kit - Insulated Ring, Spade, Fork, Hook & Butt Terminal Connectors - 22-10 Gauge - 540 PCS - Crimping Tool For Heat Shrink Connectors - Ratcheting Wire Crimper - Crimping Pliers - Ratchet Terminal Crimper - Wire Crimp Tool by Wirefy - Wirefy Heat Shrink Tubing Kit 180 PCS - 3:1 Ratio Adhesive Lined, Wire Shrink Wrap Tubing - Industrial Heat-Shrink Tubing - Black - Shrink Wrap Tubing | Trusted UL Certification --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/45127035-heat-shrink-wire-connectors-kit-marine-grade-electrical-connectors-automotive](https://www.desertcart.hr/products/45127035-heat-shrink-wire-connectors-kit-marine-grade-electrical-connectors-automotive) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-20*
