Supco t1033 Insulated Ring Terminals 20 Pack

Product Description

The SUPCO t1033 is a 20-piece pack of insulated ring terminals designed for electrical termination work in HVAC, refrigeration, and general electrical service applications. Each terminal features a brass core with tin plating and an insulated sleeve, providing a secure, corrosion-resistant connection at wire termination points. These terminals are rated for continuous use up to 221 degrees F and up to 600 volts, making them suitable for control circuit wiring and low-voltage field connections. Licensed electricians, HVAC technicians, and refrigeration service pros keep packs like this on hand for quick field repairs and panel wiring tasks.

The t1033 terminals are well suited for residential and light commercial service work where reliable, insulated ring-style connections are needed. The 20-piece count makes this pack practical for small jobs, service calls, and restocking field kits without carrying bulk inventory. Typical applications include control board wiring, motor terminal connections, and general panel or junction box terminations across HVAC and electrical trades.

Key Features

• Insulated ring terminal design for secure, strain-relieved wire connections
• Brass construction with tin plating for corrosion resistance
• Rated up to 600 volts for broad low- and line-voltage compatibility
• Maximum operating temperature of 221 degrees F (105 degrees C)
• 20-piece pack sized for service calls and small jobs

Compatibility

Designed as standard insulated ring terminals suitable for general electrical and HVAC control wiring applications where ring-style terminations are required.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements. Always de-energize and lock out the circuit before making or removing terminal connections. Use a calibrated ratcheting wire crimper to ensure full contact between the terminal barrel and conductor. Avoid over-stripping wire insulation, as excess exposed conductor increases the risk of incidental contact inside enclosures.
