Easy Identification: Color coded connector tubing Polyolefin heat shrink butt connectors improve Pullout Strength. High-quality wire connectors in Seal, Strain Relief, Cable Check and Insulation. Melted Solder ensures wires Strongly Connected and avoids wires slipping out from the terminal. Comply with all Relevant Standards: ROHS, ISO 9001:2008, SGS and CE standards. IP67 Waterproof ? The design that Polyolefin Tubing outside and Hot Melt Adhesive inside creates a durable waterproof seal between the wire and the connector. ? Waterproof Connectors would prevent any corrosion even in the most humid environments. ? Transparent Sleeve of the butt connectors provide Visual Inspection. --- You can control the operating temperature and heating time. No Crimping Required ? Sopoby solder and seal butt connectors allow you to use them in hard to reach or limited space environments. As no crimping needed, what you should do is just position the stripped wires into the solder sleeve and apply heat to finish the connection. An easy one step connection of wires, insulated and sealed. ???? FAST EASY PROCESS??Simply position the TWO stripped wires into the solder sleeve and apply heat to finish the connection. The solder will gradually flow, and the insulation tubing will shrink down, creating a waterproof seal. ???? WATERPROOF??Polyolefin tubing outside and hot melt adhesive inside would effectively improve the waterproof performance of these solder connectors. Perfect for your working on boat, vehicle, home or scientific wiring projects. ???? GREAT WIRING SOLUTION FOR LIMITED SPACE AREAS??NO Crimping Required. You can easily use these solder butt connectors in hard-to-reach or limited space areas. ???? COMPLIANT WITH ALL RELEVANT STANDARDS??Sopoby solder seal wire connectors are compliant with ROHS, ISO 9001: 2008, SGS and CE standards; Shrinking Ratio: 2: 1 Feedback We pride ourselves on providing a 5 STAR service to all of our customers and YOUR feedback is very important to us to maintain this service.
