Compression die YATO YT-21755 — hand tool accessory, 1 pc

The YATO YT-21755 compression die is a single-piece replacement accessory designed for use with compatible mechanical and hydraulic crimping tools. Supplied as one unit, this die restores or expands the crimping capability of a compression tool, allowing reliable compression of fittings, connectors and terminals during installation and maintenance tasks. It is intended as a direct wearable part for systems that accept this style of die, providing consistent crimp geometry when correctly matched to the tool and connector type.

Advantages

This replacement die offers precise, repeatable compression performance when installed in a compatible crimping head. Manufactured to withstand the forces involved in mechanical and hydraulic crimping, it provides stable contact surfaces and accurate dimensions to maintain uniform crimps. As a single-piece die, it simplifies replacement and reduces downtime for tool maintenance or changeover between different connector sizes.

Suitable for

• Field maintenance and on-site tool repair
• Crimping of electrical terminals and cable lugs compatible with the die profile
• Replacement of worn or damaged dies in mechanical or hydraulic crimping tools
• Workshops and service centres carrying out connector assembly

Key specifications

• Configuration: single-piece compression die
• Intended use: crimping/compression of fittings, terminals and connectors
• Compatibility: for use with crimping tools that accept this die design (verify tool model for fit)
• Supply: single unit (1 pc)
• Construction: engineered metal for load-bearing crimping operations

How to use

Confirm tool compatibility before installation and ensure the tool is de-energized or pressure-released if hydraulic. Remove the worn die from the crimping head following the tool manufacturer's instructions, then install the YATO compression die in the correct orientation and secure any retaining hardware. Select the appropriate connector or terminal and position it in the die. Perform a test crimp on a sample piece to verify correct fit and crimp quality, and adjust tool settings as required. Inspect each crimped connection for proper compression and absence of damage.

Usage recommendations

Use the die only with tools rated for the required crimping force and with connectors listed as compatible for that die profile. Regularly inspect the die for wear, nicks or deformation and replace it if crimp quality deteriorates. Follow safety procedures when working with hydraulic or powered tools, including wearing appropriate personal protective equipment and following the tool manufacturer's maintenance guidance.
