Our best ring terminals for preventing wire pullout and loose connections. When you apply heat, the plastic grips the wire so it stays put when tugged, vibrated, or under tension for long periods. As the barrel heats up, the solder melts the stranded wire into a solid, rigid wire that holds tighter and conducts electricity better than unsoldered wire.

The plastic insulation shrinks when heated to grip and seal the wire more tightly than other multisize ring terminals. In addition to sealing out contaminants, the heat shrink distributes strain when the wire is pulled or under tension for long periods. An extended, oblong mounting hole fits multiple screw sizes. Attach your wire with a crimping tool to avoid a damaged barrel and loose connection.
