UL and CSA rated for 600 Volts. All Nylon ring terminal connectors are color coded to industry standards: Red nylon ring terminals for 22-18GA wire. Blue nylon ring terminals for 16-14GA wire. Yellow nylon ring terminals for 12-10GA wire. Premium Nylon insulated ring terminals contain a tin-plated brass sleeve that strengthen the ring terminal barrel and secures the wire to protect against stress and high vibration. Funnel ferrule wire entrance into electrical barrel eliminates wire strand ‘hang-up’, increases crimping rates and wire termination reliability.
Terminals made of Nylon material have an operating temperature range: continuous duty from -67°F to 221°F (-55°C to 105°C)
