iCrimp Combo Pex Pipe Crimping Tool Kit - Compact Crimper for 1/2

In this review the iCrimp Combo Pex Pipe Crimping Tool Kit is evaluated as a practical, workmanlike kit for PEX plumbing tasks. The bottom line: it is aimed at DIYers and tradespeople who need a reliable, compact crimper that meets ASTM F1807 and handles both 1/2 in and 3/4 in copper rings without damaging fittings. The reviewer found the kit well suited for confined spaces, with polished jaws that protect copper rings and a clever hook on the handle that helps pre-pressurize rings to prevent slipping, making routine residential PEX work faster and less prone to leaks.

Key Features

• ASTM F1807 compliance: Ensures the crimper closes copper rings to the standard used for PEX connections, reducing uncertainty during installation.
• Dual-size compatibility: Works with both 1/2 in and 3/4 in copper rings so one tool covers the two most common residential sizes.
• Well-polished jaws: Smooth jaw faces reduce the risk of scoring or damaging copper rings, which helps avoid leaks after crimping.
• Compact handles: Short, lightweight handles improve maneuverability in tight spaces and make single-person jobs easier.
• Support hook for pre-pressurizing: The built-in hook holds and pre-pressurizes the copper ring to prevent slipping during the initial crimp pass.
• Includes removal and cutting tools: The kit bundles a removal tool and a PEX tubing cutter so installers have the basic items needed for maintenance.

Who It's For

The kit is ideal for homeowners tackling small plumbing repairs, weekend DIYers upgrading fixtures, and professional plumbers who need a compact backup tool for tight crawlspaces or service calls. Its compliance with ASTM F1807 and dual-size capability make it a practical choice for standard PEX installations where copper rings are used.

Less suitable users include those working exclusively with crimp-free systems, specialized commercial contractors who require heavy-duty hydraulic tools for high-volume installs, or installers who prefer expansion-style PEX systems; those users should look for tools tailored to their specific system.

Pros & Cons

Pros

• Compact, lightweight design performs well in confined areas and reduces user fatigue.
• Polished jaws protect copper rings and contribute to reliable, leak-free crimps.
• Dual 1/2 in and 3/4 in compatibility keeps one tool useful across common residential sizes.
• Included cutter and removal tool make the kit a practical starter set for maintenance.

Cons

• Short handles limit leverage compared with full-size crimpers, so very stiff rings may require more force.
• The ring-saving feature only works in the lower jaws near the hook and is not a universal fix for heavily deformed rings.

Specifications

Our Verdict

The iCrimp Combo Pex crimping kit is a sensible, value-focused choice for anyone doing standard PEX work with copper rings. It delivers reliable crimps to an industry standard, saves space with short handles, and includes the basic tools needed for most residential jobs. Professionals who need maximum leverage or specialized commercial tooling should consider heavier options, but for DIY and service calls this kit is good value and hard to beat for convenience.

Frequently Asked Questions

Will the polished jaws prevent leaks?
The well-polished jaws reduce damage to copper rings, which helps achieve consistent crimps and lowers the chance of leaks when used correctly.

Can the tool fix a deformed copper ring?
The crimper can help save slightly deformed rings when operated in the lower jaws near the support hook, but it is not a guaranteed fix for severely damaged rings.
