Measure your wire, and easily choose the right connector by looking at wire gauge imprint on polyolefin tubing. - ✿ 【Durablity】The 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. - ✿ 【Premium Copper】Copper barrel provides increased current flow, and ensures less 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】Polyolefin tubing on the outside and hot melt adhesive inside provides excellent waterproof property. Polyolefin tubing reduces in size and adhesive flows inside the insulation when heating. Dual-walled tubing ensures waterproof seal and prevents wire corrosion, can be ideal used whether you are working on your boat, vehicle, home or scientific projects. - ✿ 【Friendly After-sale Service & Guarantee】Please do not hesitate to contact us if you meet any problems before ordering or after receiving our products.

I used these to make a stereo cable between my F-450 and a new head unit. They worked great, and the shrinkage is fantastic - they snug so well up against the wire that the connection can't move. It's nice to have an assortment of sizes for future tasks, even though I really only needed the pink ones for this job. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Nice variety of connectors *by G***A on Reviewed in the United States on September 5, 2019* I ordered these because there are 3 different sizes of connectors. Very handy to have when working on boat. I installed a few connectors and they seem to be of good quality. Easy to install and they look good. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Quality connectors *by B***7 on Reviewed in the United States on March 23, 2020* Worth it for the cost, no issues, connectors work as intended. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/122778502-220pcs-heat-shrink-butt-connectors-sopoby-electrical-connectors-waterproof-wire](https://www.desertcart.us/products/122778502-220pcs-heat-shrink-butt-connectors-sopoby-electrical-connectors-waterproof-wire) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
