How To Use
Strip wire ends, twist neatly and insert into the connector so wires overlap at the solder ring
Apply heat evenly (recommended: heat gun) until solder melts and tubing fully shrinks
Allow to cool before pulling or moving the cable
Important Notes / Safety
Use a heat gun for best results; open flame can overheat, char the tube, or weaken the joint
Choose the correct size for the wire gauge to ensure a proper waterproof seal
Not a substitute for professional high-current terminations where specific rated connectors are required
