3M 7100165170 Bullet Connector 22-18 Awg Red 100-pack

Product Description

The 3M 7100165170 is a red nylon-insulated bullet connector designed for splicing and terminating 22 to 18 AWG wire in low-voltage electrical and control wiring applications. The connector features a 0.156-inch bullet diameter and a 0.990-inch bullet length, providing a secure mechanical and electrical connection in a compact form factor. The red nylon insulation color-codes the connector to its wire range, helping technicians quickly identify the correct connector during installation. This pack contains 100 connectors, making it well suited for service vans, panel shops, and production wiring tasks.

This connector is used in residential and light commercial wiring applications where reliable wire terminations are required on small-gauge conductors. Common install scenarios include HVAC control wiring, thermostat circuit repairs, low-voltage sensor wiring, and electrical panel accessory connections. Electricians, HVAC technicians, and pool equipment service pros frequently use bullet connectors of this type when building or repairing harnesses on 22 to 18 AWG circuits. The 100-piece package quantity supports both field service work and bench assembly environments.

Key Features

• Accepts 22 to 18 AWG wire for versatile small-gauge termination
• 0.156-inch bullet diameter provides consistent mating fit with standard bullet receptacles
• 0.990-inch bullet length for solid mechanical engagement
• Red nylon insulation provides color-coded wire-range identification and electrical insulation
• Pack of 100 connectors supports high-volume field or shop use

Compatibility

Designed for use with standard 0.156-inch bullet receptacles on 22 to 18 AWG copper conductors in low-voltage control and signal wiring applications.

Installation Notes

Installation is typically performed by licensed electricians or qualified HVAC or pool service technicians. Always de-energize the circuit and verify zero voltage before making or breaking any wire termination. Use a calibrated wire stripper to remove insulation to the correct strip length and a proper ratcheting crimp tool rated for the connector series to ensure a gas-tight crimp. Verify the completed crimp with a firm pull test before energizing the circuit.
