The SUPCO t2070 is a porcelain wire connector sold in a 10-piece pack, designed for making secure, heat-resistant electrical connections in HVAC, appliance, and general trade service applications. Rated for use up to 600 volts, the porcelain construction handles elevated temperatures that standard plastic connectors cannot. These connectors are a standard item for HVAC technicians, appliance repair pros, and electricians performing terminal service work on equipment where high heat or flame proximity is a concern.
The t2070 is suited for residential and light commercial service calls where quick, reliable wire terminations are needed near heat sources such as furnace burner assemblies, boiler controls, or appliance heating elements. The 10-piece pack format keeps inventory manageable for technicians who service these connections regularly and need a cost-effective supply on hand without over-ordering bulk quantities.
Designed as an OEM-style replacement porcelain wire connector for HVAC, appliance, and general electrical service applications requiring heat-resistant terminal connections rated to 600 volts.
Installation is typically performed by licensed HVAC technicians or electricians. Always de-energize and lock out the equipment at the disconnect or breaker before servicing any wiring or terminals. Confirm the connector is fully seated and the wire gauge is appropriate for the connection before restoring power. Work should comply with applicable NEC requirements for the installation environment.
