Pro Press Copper Crimper Propress Tool with 4 Jaws - Battery Powered

In this review the Pro Press Copper Crimper proves to be a serious workhorse for plumbers and HVAC techs who need fast, consistent crimps on US standard copper or stainless steel pipe. The single biggest reason to buy is its combination of a 42KN pure copper motor and high-capacity 5.0Ah batteries that deliver rapid, repeatable crimps - the kit is ready for a full day on the job with the supplied batteries, charger, and four dies. It is a practical, rugged solution when speed and reliability matter.

Key Features

• 42KN Pure Copper Motor: Delivers powerful, consistent crimping force so fittings close cleanly in 3-6 seconds.
• 5.0Ah Batteries: Two high-capacity 18V batteries allow more than 400 continuous crimps and extend runtime compared with lower-capacity packs.
• Four US Standard Dies: Includes 1/2', 3/4', 1', and 1-1/4' dies to cover most residential and light commercial copper and stainless runs.
• 4-Jaw Universal Fittings: Upgraded 360 swivel jaws work with most major press fitting brands for wide compatibility on site.
• Safety and Cooling: Built-in temperature sensor and ventilation slots help protect the tool during continuous use.
• LED Lights and Swivel Head: Improves visibility and access in tight or low-light plumbing and HVAC spaces.

Who It's For

The Pro Press Copper Crimper is aimed at plumbers, heating contractors, and serious DIYers who regularly install or repair copper and stainless steel lines and need quick, reliable crimps across common US pipe sizes. Its fast cycle time and high battery capacity make it especially useful on jobs where multiple connections are required each day.

Those who should look elsewhere include users who need smaller, ultra-light shear tools for occasional one-off tasks, or tradespeople who require specialized dies larger than 1-1/4' for commercial piping work. Also, buyers who require corded-only tools for unlimited runtime may prefer a different model.

Pros & Cons

Pros

• Powerful 42KN pure copper motor provides quick, consistent crimps across the included sizes.
• Two 5.0Ah batteries deliver long runtime so the tool can handle dozens to hundreds of crimps per charge.
• Comprehensive kit includes four dies, charger, storage box, and instructions for immediate use on site.
• 360 swivel jaws and LEDs make it easy to work in tight, dimly lit areas.

Cons

• The tool is noticeably heavy for prolonged overhead use, which some users may find fatiguing.
• Dies are limited to 1-1/4' maximum, so it is not suitable for larger commercial pipework without additional tooling.
