Sta-Kon 18RA-516X – Frequently Asked Questions
1) What wire gauge does the Sta-Kon 18RA-516X ring terminal accept?
The 18RA-516X is sized for 22 to 18 AWG stranded copper wire. The red vinyl insulation is the standard color code for that gauge band, so on a panel where crimps are color-checked, red tells the inspector it is the 22-18 terminal. Anything heavier than 18 AWG will not seat in the barrel.
2) Is this ring terminal copper or aluminum, and can I use it on aluminum conductors?
The barrel is copper, so it is intended for copper conductors only. Terminating aluminum wire needs a terminal rated AL/CU; a copper-only crimp on aluminum invites galvanic corrosion and a loose joint over time.
3) Ring terminal or fork terminal for a screw-down terminal block?
Use the ring style, like the 18RA-516X, anywhere vibration or safety matters: the closed ring cannot pull off a loosened screw. A fork (spade) terminal is faster to service because you can slide it out without fully removing the nut, which is why panel shops use forks on frequently changed circuits. For motor studs, battery posts, and ground studs, ring wins.
4) What crimp tool do I need for a 22-18 AWG insulated ring terminal?
Use an insulated-terminal crimper on its red nest, which is the 22-18 AWG station on standard color-coded hand tools. The die compresses the barrel through the vinyl without splitting it. Pliers or a non-insulated die will cut the sleeve and leave an unreliable crimp.
5) Does the vinyl insulation on the Sta-Kon 18RA-516X need separate heat shrink or tape?
No. The vinyl sleeve is factory-applied over the barrel and covers the crimp and the wire entry, so no extra tape or shrink is needed in a dry enclosure. If the connection is exposed to moisture or splash, step up to a heat-shrink insulated ring terminal instead, since vinyl is not a sealed barrier.
6) Are Sta-Kon ring terminals made in the USA?
Yes, the 18RA-516X ring terminal is US made, which is the box to tick on government, military, and Buy American funded work where domestic origin has to be documented.
