RVBOATPAT Insulated Inline Splice Connector 2-14 AWG 5 Pack

2-14 AWG Inline Splice Connector

This UL Listed insulated connector joins copper and aluminum wires from 2 AWG through 14 AWG in a single in-line port. Each connector uses a hex-head screw to secure the conductors and ships with antioxidant lubricant in the ports. The black UV-resistant plastisol insulation provides dielectric strength and chemical protection. A pack contains five connectors for multiple splices.

Sustained Load Performance

The connectors are rated for continuous operation at 600V across a temperature span of -49°F to 194°F. The antioxidant lubricant reduces oxidation at the contact interface during long-term current flow. Aluminum construction dissipates heat from mixed-metal joints to limit temperature rise under steady loads. The plastisol insulation maintains its dielectric properties throughout the rated thermal range.

Aluminum-to-Copper Compatibility

The single specification that decides fit is the ability to splice aluminum wire to copper wire safely within the 2-14 AWG range. The design prevents overheating caused by galvanic action between dissimilar metals. Installers who only join copper-to-copper may choose a simpler connector, while those joining aluminum-to-aluminum or aluminum-to-copper need this specific capability.
