- HIGH-QUALITY COPPER CORE:Heat shrink butt connectors use a copper core with a higher thickness rating.This makes your connection project safer and better meets our customersโ quality needs
- HIGH-QUALITY HEAT SHRINK:Translucent heat shrink tubing provides high tensile strength and resistance to stretch and minimize mechanical damage.The thick barrel ensures a strong crimp every time.The inner wall of the heat-shrinkable tube has enough hot melt adhesive to ensure waterproof performance reliability.Your wire will never slip out of these heat shrink wire connectors
- RECOGNIZABLE:Tubings of varying colors with easily recognizable wire gauge markings. Simply measure the wiring, and by checking the mark of wire gauge of the polyolefin tubing, then you can quickly choose the right connector
- WIDE APPLICATIONS: High quality 3:1 shrinkage tubing has a heat-activated sealant lining to provide complete secure seal. It's flame-retardant, waterproof, and can be used underground. Compliant with all electrical standards, Perfect for marine and automobile applications, whether you are working on your boat, Vehicle, Home or scientific project
- โ๏ธใPREMIUM QUALITYใThick copper barrel ensures strong secure crimping every time, providing minimal voltage drop, high current flow, and less heat. These will prevent short circuits and problematic wiring that inferior connectors are known for
- โ๏ธใDURABILITYใEach terminal features a thick tinned copper barrel that resists corrosion to hold the wire tight when crimped. The barrel is created from one seamless piece of copper that eliminates the problem of the barrel opening. Your wire will never slip out of the connector
- โ๏ธใWATERPROOFใInsulation tubing has unique dual-walled design. High quality 3:1 shrinkage tubing has a heat-activated sealant lining to provide a 360 degree secure seal. It's flame-retardant, waterproof, and can be used underground
- โ๏ธใWIDE APPLICATIONSใCompliant with all electrical standards, Perfect for marine and automobile applications, whether you are working on your boat, Vehicle, Home or scientific project, our electrical crimp connector will ensure strong watertight seal to make sure everything bond correctly. The connector assortment includes red (AWG 22 โ 16), blue (AWG 16 โ 14) and yellow (AWG 12 โ 10) butt connectors that can be used on wire AWG from 22 to 10
- โ๏ธใTICONN BRAND QUALITY COMMITMENTใWe stand behind the quality of our products. If for any reason you are not satisfied with your purchase, please contact us.
- Time Saver: Solderless,crimpless, all you need is just a heat gun to finish the joint, much faster and easier than the old way
- Fit for Confined and Narrow Spaces: Can be bent after connection and no need to crimp or solder in the confined area, just control the temperature via a heat gun
- Waterproof and Seal Performance: There is two hot melt waterproof adhesive rings in each butt connector, which help it hold up better to moisture
- High Temperature Proof in A Short Time: Use exclusive material in the butt connectors to avoid shrink tubing melting before solder ring
- IATF16949:2016 Listed: The Kuject solder seal connectors meet the newest standard of International Automotive Task Force, which is the most standardized way for you to repair or modify your car
- [EXECELLENT QUALITY] : Direct factory with excellent quality control, STRONG & DURABLE. The copper core of our heat shrinkable joints is made of high quality tinned copper, in addition to being extremely conductive, it is easier to flatten and grip the wire
- [EASY USE] : Take two wires you wish to join. Remove the wire insulator, pick the terminal color you want. Insert the wire into the terminal one at the time and crimp by crimping tool, insert another terminal and crimp. Use air gun to apply heat on the heat shrink connectors.
- [PRACTICAL DESIGN] : Double-wall design, outer layer of polyolefin tube, inner layer of hot melt adhesive, precise crimping and good contact. Electrical butt connectors provide high tensile strength and adequate hot melt adhesive inside the tube. After shrinking, the wiring is firm and not loose, and it can ensure that the current continues to flow smoothly.
- [WIDE APPLICATIONS] : Our waterproof terminals are perfect for marine, automobile applications, electrical and electronics industries. Whether working on your Boat, Vehicle, Home, or Scientific project, the electrical crimp connector will ensure a strong waterproof seal to make sure everything bonds correctly.
- [PACKAGE INCLUDED] : 25 pcs red connector ( 22-16 AWG ), 15 pcs blue connector ( 16-14 AWG ), 10 pcs yellow connector ( 12-10 AWG ).
