Sta-Kon RA18-8 Ring Terminal

The Sta-Kon RA18-8 is a nylon-insulated ring terminal designed for electrical wiring tasks requiring a secure crimp connection. It suits installers and technicians working with copper conductors in automotive, industrial or general-purpose circuits. The red insulation provides partial coverage and identifies the terminal for 16 AWG wire. It is certified to CSA and UL E9809 standards.

16 AWG capacity and 600 V rating

This terminal accepts wire sizes from 22 AWG up to 16 AWG, giving headroom for smaller conductors while remaining firm at the maximum gauge. The 600 V rating covers typical low-voltage power and control circuits. It runs out of capacity beyond 16 AWG wire or voltages exceeding 600 V, so larger conductors or higher-voltage systems need a different terminal.

Crimp termination and #8 stud constraints

The crimp-style barrel uses a serrated design and tin-finished copper to grip the conductor mechanically. The tongue width is .26 in with a barrel length of .46 in, and the hole spacing is .25 in for a #8 stud. These fixed dimensions mean the terminal only fits #8 hardware and cannot accommodate larger studs or different mounting patterns. The nylon insulation withstands up to 221 degrees F.

Questions about this item

Will the RA18-8 ring terminal crimp onto the 16 AWG wires I already have in my harness?

Yes, the terminal accepts copper conductors from 22 AWG up to 16 AWG, so your existing 16 AWG wires are at the upper end of the supported range.

How can I verify the crimp is solid once I have installed the terminal?

After crimping with the proper tool, tug the wire firmly; it should not pull out of the serrated barrel, and the tin-plated copper barrel should show even deformation around the conductor.

Does the package include any crimp tool or heat-shrink tubing, or must I buy those separately?

The package contains only the nylon-insulated ring terminals; a compatible crimp tool and any additional insulation such as heat-shrink tubing are sold separately.
