Applications

Automotive lighting, accessories, stereo, battery, and grounding repairs
Marine, trailer, RV, motorcycle, and outdoor electrical connections
Control panels, terminal blocks, appliances, and workshop projects
Not for wire gauges, conductor materials, voltage, or temperatures outside the product specification

How to Choose

Choose the connection point first: inline splice, stud, screw, blade, or terminal block.
Match every conductor to the connector's stated AWG range and barrel size.
Select adhesive-lined heat shrink where moisture, vibration, or corrosion is expected.
Confirm pack quantity, terminal size, and compatibility on the product page before ordering.

How to Use

Disconnect power, cut away damaged wire, and strip the specified insulation length.
Insert the conductor fully; crimp with the matching die or heat a solder-seal connector evenly.
Shrink the sleeve, allow it to cool, then perform a visual check and gentle pull test.
Do not install on an incompatible gauge or conductor material.

Wire Connector FAQ

How do I choose the correct wire connector size?

Check the conductor gauge and choose a connector whose stated AWG range includes that wire. For terminals, also match the stud, screw, or blade size.

Are these wire connectors compatible with automotive and marine wiring?

Yes, when the AWG range, conductor material, terminal size, and sealing level match the application. Use adhesive-lined heat-shrink styles for exposed automotive and marine locations.

How do I install wire connectors correctly?

Disconnect power, strip the specified length, insert the conductor fully, and use the correct crimping die or controlled heat method. Finish with a visual inspection and pull test.
