Thomas Betts RA18-6 Ring Terminal 22-16 Awg Crimp 100pk

Product Description

The THOMAS BETTS RA18-6 is a partially insulated, D-shaped ring terminal designed for crimp connections on 22 to 16 AWG copper wire. The copper contact features a tin (TiN) plating to resist corrosion and maintain a stable electrical connection. A nylon insulation sleeve partially covers the barrel, providing a degree of mechanical protection without fully enclosing the connection point. At 0.86 inches long and 0.26 inches wide, this compact terminal fits size 6 studs and suits tight wiring layouts. Electricians and panel wiring technicians use these terminals where reliable, code-compliant ring connections are required in control panels, junction boxes, and low-voltage wiring assemblies.

This terminal is suited for residential and light commercial electrical applications where 22 to 16 AWG wire terminates to a size 6 stud or screw. Common install scenarios include control panel wiring, instrumentation circuits, and HVAC low-voltage control wiring. The red color coding follows the industry-standard color convention for this wire gauge range, helping technicians quickly identify the correct terminal during assembly. Sold in a pack of 100, this terminal is practical for production wiring work or service truck stocking.

Compatibility

Designed for crimp termination onto 22 to 16 AWG copper conductors and size 6 stud or screw connections in standard electrical panel, control, and low-voltage wiring assemblies.

Installation Notes

Installation should be performed by a qualified electrician following applicable NEC requirements. De-energize the circuit completely before terminating or disturbing any wiring. Use a calibrated ratcheting crimp tool rated for the terminal and wire gauge combination to ensure a proper, gas-tight crimp. Do not solder after crimping on terminals specified for crimp-only termination, as this can compromise the connection integrity.
