The SUPCO t1118 is a 15-piece set of high-temperature ring terminals designed for electrical service and repair applications. Built from brass with tin plating, these terminals provide reliable conductivity and corrosion resistance in demanding environments. Rated for use up to 600 volts, they are suitable for a wide range of residential and light commercial wiring tasks. Licensed electricians, HVAC technicians, and field service professionals keep packs like this on hand for quick terminal replacements during service calls where carrying a full connector assortment is not practical.
These ring terminals are well-suited for control circuit wiring, panel connections, and equipment service work where a secure, insulated ring connection is required. The compact 15-piece pack format makes it practical for toolbox or service van storage. They are appropriate for any application calling for a brass ring terminal rated to 600 volts, including low-voltage control wiring and line-voltage connections within that rating.
Designed as a general-purpose ring terminal service pack suitable for residential and light commercial electrical and HVAC control wiring applications rated up to 600 volts.
Installation should be performed by a qualified electrician or licensed HVAC technician in accordance with NEC requirements. Always de-energize the circuit and verify zero voltage with a meter before making or breaking any terminal connections. Use an appropriate wire crimping tool rated for the terminal size to ensure a secure mechanical and electrical connection. Avoid over-crimping, which can crack the brass body and compromise the connection.
