【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. 【EASY TO IDENTITY】 - Color-coded tubing with wire gauge imprint makes it easy to identify the size of the connector for every application. Measure your wire, and easily choose the butt connector by looking at wire gauge imprint on polyolefin tubing. 【FRIENDLY AFTER-SALE SERVICE & GUARANTEE】 - Please do not hesitate to contact us if you meet any problems before ordering or after receiving our products.
