3M 7010349237 Ring Terminal 22-18 Awg Crimp 5/16 Inch

Product Description

The 3M 7010349237 is a partially insulated circular ring terminal designed for crimp connections on copper wire conductors ranging from 22 to 18 AWG. The terminal features a copper contact and a nylon insulation sleeve in red, making it easy to identify wire gauge range at a glance during panel wiring or harness assembly. The 5/16-inch stud size suits a wide range of lug and fastener configurations common in electrical and control panel work. This terminal is sold in a package quantity of 100 units, making it well suited for production runs, panel shops, and field service kits alike.

This ring terminal is used in residential and light commercial electrical applications wherever a secure, vibration-resistant lug connection is required. Typical install scenarios include control panel wiring, low-voltage circuit terminations, HVAC equipment harnesses, and equipment grounding connections. The 22 to 18 AWG wire range covers common control wiring wire sizes used across HVAC, plumbing controls, and general electrical service work. Electricians and HVAC technicians are the primary installers.

Key Features

• Partially insulated nylon sleeve in red for 22 to 18 AWG wire identification
• Copper contact construction for reliable conductivity and crimp performance
• 5/16-inch stud size accommodates common panel and equipment fastener sizes
• Crimp connection type — no soldering required, compatible with standard ratchet crimpers
• CSA Certified and UL Listed for use in code-compliant installations
• RoHS 2011 and EU Compliant; suitable for both domestic and export equipment builds

Compatibility

Designed as an OEM-style ring terminal for crimp-type lug connections on 22 to 18 AWG copper conductors in residential and commercial electrical, HVAC control, and equipment wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians. Always de-energize the circuit and verify zero voltage with a meter before terminating any conductor. Use a calibrated ratchet-style crimp tool sized for the 22 to 18 AWG range to achieve a full, gas-tight crimp — avoid plier-style crimping, which can produce an unreliable connection. Reference NEC Article 110 for general termination workmanship requirements applicable to ring-lug connections.
