High temperature ring terminals are designed for electrical connections that are exposed to higher temperatures that would cause other ring terminals to fail. Made from nickel plated steel and can operate in temperatures as high as 900°F (482°C). Because of the higher temperatures, these ring terminals should only be crimped and not soldered. Because high temperature ring terminals are made from steel, they require much more force to crimp than standard ring terminals. Common uses for high temperature ring terminals include electrical connections for exhaust sensors, manifolds, heaters and heating elements, ovens, dryers, and more. Rated for use in electrical connections up to 600 volts. Made in the USA.
