Ring Terminal for 16 AWG Wire

This Sta-Kon RA18-14 ring terminal connects 16 AWG copper conductors to a 1/4 inch stud. It is built for electrical and industrial wiring tasks where a secure crimp connection is required. The nylon insulation provides partial coverage and is rated for 600 volts maximum.

Nylon Insulation and Serrated Barrel

The red nylon insulation withstands temperatures up to 221 degrees Fahrenheit. A serrated barrel design grips the wire strands during crimping to resist pull-out. Tin-plated copper contacts ensure conductivity and corrosion resistance for the life of the connection.

Crimp Installation with Standard Tools

Install using a crimp tool matched to 16 AWG terminals; no soldering is required. The partial insulation coverage means the installer must verify correct wire strip length to avoid exposed conductor. Mis-crimping the serrated barrel can weaken the mechanical hold on fine strands.

Questions about this item

Will the nylon insulation need replacement after repeated heat cycles near 221 degrees F?

The nylon insulation is rated to 221 degrees F and designed for permanent crimp connections; it does not require scheduled replacement under normal operating temperatures.

What limits continuous current before the 16 AWG copper barrel overheats?

The 16 AWG maximum wire size and 600 V rating set the electrical limit; sustained current must stay within the ampacity of the installed 16 AWG copper conductor.

Does the tin-plated copper contact generate noticeable heat during all-day operation?

The tin-plated copper barrel and serrated crimp design provide low-resistance contact; heat rise stays minimal when crimped to the correct 16 AWG wire and operated within the 600 V rating.
