High temperature push on terminals are special push on terminals designed for use in high temperature electrical applications such as engines, ovens, exhaust systems, furnaces, and other higher temperature electrical connections that can cause regular copper push on terminals to fail. These push on quick connect terminals are constructed from nickel plated steel and are harder to crimp than copper terminals. Soldering is not recommended since the higher temperatures will cause the solder to melt. Our video shows how to crimp and use a high temperature push on terminal. Rated for continuous operating temperature of up to 900°F (482°C). Voltage rating of up to 600 volts. Made in the USA.
