Product Description: Function: Temperature Specification Minimum Melting Temperature: 138C Minimum Compression Temperature: 80C Working Temperature: -55-125 Compression Temperature > 160C Material: PE, welded Product name: hot welding can be performed Maximum voltage: 600V polyene material Recovery: 2:01 Dielectric strength: 1kw Protection level: IP67 include: 200 x red shrink connectors 180 x blue shrink connectors 80 x white shrink connectors 40 x yellow shrink connectors Features: Designed with polyacrylic tube outside and thermal adhesive inside, it creates a durable waterproof seal between wires and connectors. Watend connectors will prevent corrosion even in the most humid environment. Feature: The transparent sleeve of the butt connector allows for visual inspection. --- You can control the working temperature and heating time. Easy identification: different colors for different sizes of connectors Can be perfectly used in marine and automotive applications. Feature: The sealed connectors allow you to use them in hard-to-reach environments or limited spaces. Since no setup is required, you simply place the bare wire into the solder sleeve and apply heat to complete the connection. Simple connection, insulation and sealing in one step of the wire. feature: Insulation protection: used to seal threaded connections, prevent electric leakage and prevent rodents from interfering with circuits When the welding ring is heated, the melt and flow into the wire connection, effectively preventing the connection from breaking. how to use: 1. Let's jump the wire through the connector tube to the end of the right size, get the connection and wire handling right, and move the connector so that the part of the welding ring is aligned with the wire connection; 2. Use a heat gun to plug the ends of the tube so that they shrink. The waterproof ring when heated will turn into a waterproof ring; how to use: 3. Heat the solder ring with a heat gun until the ring forms and penetrates the wire connection; WARNING: Heat the heating conduit section until it is close to the constriction around the wire; too much heating will completely melt the heating conduit. The solder ring must be heated thoroughly to access the wire connection. Package Included: Solder Ring Set * 1 Main points: 1. The product size is measured manually, there may be some errors 2. Since different monitors display different colors, please refer to the actual color you received. 3. Please confirm the size before purchasing.
