[Easy to Use and Solderless] Our connectors feature a solderless design, making them convenient and user-friendly. They offer a secure and reliable quick connection without the need for soldering, saving you time and effort. [Thickened Canned Copper Structure] We use thick wall red copper connectors to maximize the conductivity and durability. These connectors are usually made of 0.028 to 0.04 inches (0.7mm-1mm) thick copper, which can provide excellent conductivity and ensure the safety of the project. [3: 1 Thermal Contraction Ratio] Our connector has a 3: 1 heat contraction ratio to ensure the appropriate contraction of the pipeline. This can ensure that the tightly sealing welded stitching and insulation around the wire can prevent any sliding or disconnecting connection. Please rest assured that your wire will be closely connected to the thermal contraction connector. [Cable Gauge and Capacity] Our connector terminal assortment includes a wide range of docking connectors in red (AWG 22-16), blue (AWG 16-14), white(AWG26-24)and yellow (AWG 12-10). These connectors are designed to accommodate wire sizes ranging from AWG 26to 10. It is crucial to verify the compatibility of your specific wire size to ensure optimal electrical performance and a safe and secure connection. [Marine-Grade Quality] Our heat shrink butt connectors Kit design has marine quality and waterproof function. You can believe that these connectors will provide special protection for water, saline and corrosion to ensure lasting and reliable performance in the marine environment.
