3M 7010399303 Ring Terminal 22-18 Awg Crimp 100 Pack

Product Description

The 3M 7010399303 is a partially insulated circular ring terminal designed for secure crimp connections in low-voltage wiring applications. Built with a copper contact and red vinyl insulation, this terminal accommodates 22 to 18 AWG wire and fits a No. 10 stud. At 0.93 inches in overall length and 0.31 inches in ring width, it delivers a compact, reliable termination point. Electricians and panel technicians use these terminals when connecting control wiring to terminal blocks, circuit boards, or grounding studs where a secure mechanical and electrical bond is required. This listing covers a package of 100 terminals.

This ring terminal is suited for residential and light commercial electrical work, HVAC control wiring, and panel terminations where 22 to 18 AWG conductors are used. The crimp connection eliminates the need for soldering, allowing for fast, consistent terminations in the field or on the bench. The red color coding aligns with the industry standard for 22 to 18 AWG wire range, making polarity and gauge identification straightforward during installation and inspection.

Key Features

• Partially insulated vinyl sleeve provides protection at the barrel while leaving the ring exposed for stud contact
• Crimp connection type for fast, solder-free termination
• Copper contact material ensures reliable electrical conductivity
• Compatible with 22 to 18 AWG wire for control and low-voltage applications
• Red color coding identifies the 22 to 18 AWG wire range at a glance

Compatibility

Designed as an OEM-style crimp ring terminal for use with 22 to 18 AWG copper conductors terminated at No. 10 studs in residential and commercial electrical and control wiring applications.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize all circuits before terminating or inspecting connections. Use a calibrated ratcheting crimp tool rated for the wire gauge and terminal type to ensure a proper mechanical crimp. Inspect each terminated connection for secure seating of the wire in the barrel before applying load.
