Ecm Industries Llc 10-121 Butt Splice Connector 22-18 Awg 100 Pack

Product Description

The ECM INDUSTRIES LLC 10-121 is a solderless butt splice connector designed for making secure, in-line wire terminations on 22-18 AWG conductors. Each connector crimps onto stripped wire ends without solder, creating a reliable mechanical and electrical connection. This pack includes 100 individual connectors, making it well suited for service trucks, panel wiring jobs, or any application where a large quantity of small-gauge splices is needed. Electricians and low-voltage technicians reach for solderless butt connectors when field splicing control wiring, sensor leads, or thermostat wire where a clean, code-acceptable termination is required.

These connectors are appropriate for residential and light commercial wiring tasks involving small-gauge conductors in the 22-18 AWG range. Common applications include HVAC control wiring, thermostat wire splices, low-voltage signal circuits, and general electrical panel and appliance wiring. The 100-piece pack format is practical for service professionals who need a ready supply on hand for recurring splice work across multiple jobs.

Key Features

• Solderless crimp design — no heat or flux required for termination
• Compatible with 22-18 AWG wire gauge range
• 100 connectors per pack for high-volume or multi-job supply
• Butt splice configuration for straight in-line wire joining
• Clam shell packaging for organized storage and dispensing

Compatibility

Designed as a standard solderless butt splice connector for 22-18 AWG conductors used in low-voltage control, signal, and general electrical wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified technicians following applicable NEC requirements for the circuit type being serviced. De-energize the circuit completely before stripping and terminating any conductors. Use a calibrated wire stripper and a proper ratcheting or compression crimp tool sized for the connector to ensure a secure, low-resistance termination. Avoid over-stripping wire ends, as excess bare conductor beyond the connector barrel can create a short hazard.
