HKS Crimping Tool for Delphi APTIV & Metri-Pack Connectors - Solid OEM

In this review the HKS crimping tool shows itself as a purpose-built hand tool for technicians who need reliable crimps on Delphi APTIV Weather Pack and Metri-Pack sealed connectors. The bottom line: it is designed for AWG 18-14 (1.0-2.5mm2) terminals and stands out because of its ratcheting mechanism and precision-machined chromium-molybdenum jaw, which together deliver consistently solid crimps for OEM-style sealed connectors.

Key Features

• Ratcheting mechanism: The full ratchet cycle ensures the correct crimp profile is formed before automatic release, reducing undercrimps and user guesswork.
• Precision-machined die: A purpose-built crimp die provides repeatable, tight crimps for Delphi APTIV and Metri-Pack 150, 280, 480 and 630 style sealed terminals.
• Adjustable crimp force: A tension adjustment knob lets the user fine-tune crimp strength for specific terminal types or wire sizes within the AWG 18-14 range.
• Quick release lever: The quick release allows the jaw to be opened at any point in the cycle, which helps with misfeeds or when repositioning a connector.
• Chromium-molybdenum cutting jaw: EDM-processed chrome-moly steel jaw delivers high hardness and precise wire cutting and holding during the crimp.
• Ergonomic handles: Cushioned, non-slip grips reduce hand fatigue and improve control during repetitive crimping tasks.

Who It's For

This tool is aimed at automotive electricians, fleet maintenance techs, and hobbyists who frequently work with sealed Delphi APTIV and Metri-Pack series connectors and need consistent OEM-style crimps. Its ratcheting action and adjustable force make it suitable for repetitive workshop tasks where reliability matters.

It is less appropriate for users needing a wide wire-size range beyond AWG 18-14 or for those who require universal interchangeable dies; customers who need crimps for very large gauge cables or for a broad variety of terminal families should consider a different, multi-die crimper.

Pros & Cons

Pros

• Solid, repeatable crimps thanks to the ratcheting mechanism and precision die.
• Adjustable crimp force provides control for different terminals within the supported range.
• Durable chromium-molybdenum jaw with EDM finish gives precise cutting and long life.
• Comfortable non-slip handles reduce fatigue for extended use.

Cons

• The tool is limited to AWG 18-14 (1.0-2.5mm2) and specific Delphi/Metri-Pack models, so it is not a universal crimper for all terminals.
• Some users report a learning curve to master the release mechanism and proper wire placement.
