Brand: Kuject
Color: RED BLUE YELLOW WHITE
Specification:  
 Shrinkage ratio is 2:1  
 Temperature that start to shrink: 80℃  
 Temperature that solder ring start to melt: 111˚C 
 Temperature that solder ring melt completely：138˚C 
 Note: It means the temperature of surface of the connector, rather than the temperature that the hot air gun should set.  How to use:  
 1.Strip the two wires that going to connect and select the right size of connector. 
 2.Thread the connector to one of the wires and then twist the two conductor together. 
 3.Move the connector to the middle of the conductor. 
 4.Apply heat to the connector slowly and evenly with a hot air gun with nozzle until it melt with the wire.  Note:    Some of our customers can use lighter to finish the joint, but we recommend that it is better to use a heat gun with nozzle to heat shrink the connector.  Please rotate the wire when you are heating or surround the wire to heat so that the tube was heated evenly.  3-5 cm (1.18-1.96 inch) is the suitable distance we recommend from the nozzle to the connectors.   Package Include:  
 1.30 x White Connectors: Diameter 1.7 mm, able cross-section 0.25-0.34 mm²(A.W.G.:26-24);  
 2.40 x Red Connectors: Diameter 2.7 mm, Cable cross-section 0.5-1.0 mm²(A.W.G.:22-18);  
 3.40 x Blue Connectors: Diameter 4.5 mm, Cable cross-section 1.5-2.5 mm²(A.W.G.:16-14);  
 4.10 x Yellow Connectors: Diameter 6.0 mm, Cable cross-section 4.0-6.0 mm²(A.W.G.:12-10). 
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.
Better 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 Resistance 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 and safest way for you to repair or modify your car.
