Here’s a deeper look at ring style terminals.

Ring Terminal Styles and Features

Ring terminals connect a single wire to a single connection point, such as a circuit protection device or power source. They come in sizes from 22 gauge all the way up to 4/0 gauge for heavy-duty applications.

At State Wire, we provide the following types of ring terminals:

	Brazed Seam. The barrel is bonded with a special silver brazing alloy to prevent the seam from opening from stress or when the wire is pulled. Brazed seam terminals may be crimped from any direction.
	Shrink Tubing. With this style, the adhesive-lined heat shrink tubing provides a corrosion resistant crimp connection, which improves mechanical performance and abrasion resistance.
	PVC (Plastic) These feature a flared PVC insulation sleeve that is permanently attached to the barrel. The funneled wire entrance of this style eliminates wire strand “hang up.”
	Nylon Insulated. The nylon insulation of these terminals provides superior protection. A vibration support sleeve strengthens the barrel and secures the wire to protect against stress and vibration.
Butted Seam. Butted seam terminals are available upon request for 22-18GA and 16-14GA sizes.

Ring Terminal Selection Tips

When selecting the right ring terminal for your application, you should know the wire gauge and stud size to which you will be connecting the ring terminal. You will also want to keep in mind the connection environment in order to determine which type of insulation you will want to use.
