Cable Crimper 3M E-9Y Yellow

The 3M E-9Y Yellow cable crimper is a hand tool for crimping connectors onto cables. It features stepped jaws and a long nose that deliver a parallel crimping action, an integrated side wire cutter, insulated handles and a return spring. The tool provides a 3-to-1 mechanical advantage and is finished in yellow for easy identification in a toolbox. It is suitable for many common connector types such as UAL, UG and UR2 when used within the supported conductor sizes.

Advantages

Stepped jaws and long-nose design allow consistent, parallel crimps. The built-in side cutter reduces the need for a separate tool, and insulated handles improve grip and user safety. A return spring speeds repetitive operations while the 3-to-1 mechanical advantage reduces the manual force required for crimping.

Suitable for

• Crimping UAL connectors
• Crimping UG connectors
• Crimping UR2 connectors

Key specifications

• Brand: 3M
• Model / MPN: E-9Y
• Color: Yellow
• Mechanical advantage: 3-to-1
• Features: stepped jaws, long nose, integrated side wire cutter, insulated handles, return spring
• Not recommended for 19 AWG (0.9 mm) and larger conductors; not for 19+ wire gauge or 19 gauge, 3-wire applications

How to use

Place the prepared conductor and connector in the appropriate jaw area, then squeeze the handles until the crimp is complete and the return spring opens the tool. Use the integrated side cutter to trim excess wire before or after crimping as required. Follow the connector manufacturer’s instructions for correct positioning and crimp dimensions.

Usage recommendations

Do not use this tool for 19 AWG (0.9 mm) or larger conductors and avoid 19 gauge, 3-wire applications due to possible fatigue; select a crimper rated for larger conductors when needed. Inspect crimps and connectors visually and with a pull test per installation standards.
