Electrical Wire Splice Kit

This Master Appliance kit contains fifty-five multicolored butt splice connectors rated for wires from 24 AWG up to 10 AWG. Each connector uses a crimp termination style with a polyolefin insulation that shrinks and seals when heated. The operating temperature reaches 230 degrees Fahrenheit. The assortment covers several manufacture model numbers including 11543, 11544, 11545 and 11840.

Automotive And General Wiring Users

These connectors suit technicians joining aluminum or copper conductors in automotive, marine or industrial harnesses where a sealed crimp joint is required. The kit is not intended for buyers who need a non-insulated terminal, a larger gauge than 10 AWG, or a connector type other than a butt splice.

CSA And UL Listed Crimp Terminals

The product carries both CSA and UL safety certifications and is RoHS compliant. It is compatible with the Solderseal series. A California Proposition 65 warning applies because the item contains a chemical known to the state to cause cancer and birth defects or other reproductive harm.
