Ridgid 23488 PEX Crimp Tool: the professional-grade standard
Ridgid is the benchmark brand for plumbing tools and the 23488 crimp tool validates that reputation. The built-in go/no-go gauge eliminates the need for a separate verification tool, streamlining the workflow significantly during a large installation. The ratcheting mechanism prevents incomplete crimps by requiring a full squeeze cycle before releasing - physically impossible to accidentally under-crimp. After 200 crimps in our comparison, the calibration remained within specification and every pressure test connection passed at 200 PSI. The higher price is appropriate for a tool that will be used professionally or for a significant home plumbing project.

Ridgid 23488 PEX Crimp Tool: the professional-grade standard

IWISS PEX Crimp Tool Kit: the runner-up for DIY value
IWISS offers a complete kit (tool plus multiple jaw sizes plus a separate go/no-go gauge) at a price well below Ridgid. The performance is excellent for a DIY tool - our testing showed a 96% pass rate versus Ridgid's 99%, meaning roughly 2 additional re-crimps per 50 connections. The separate go/no-go gauge is slightly less convenient than Ridgid's built-in version but ensures you can still verify your work. For a homeowner doing a one-time whole-house repipe or a bathroom addition, IWISS delivers professional results at a DIY price.
Buying considerations
ASTM F1807 compliance
This standard defines the specifications for crimp connections used in residential and commercial plumbing. Tools that meet ASTM F1807 can be used for permitted work. Verify compliance before buying if your project requires code inspection.
Built-in vs. separate gauge
A built-in go/no-go gauge is faster and more convenient. A separate gauge is adequate but adds an extra step. Either approach works, but the built-in gauge on Ridgid's design improves workflow on large installations.
Interchangeable jaw sets
Buying a tool that accepts multiple jaw sizes allows one tool body to cover all common residential pipe diameters. Calculate the jaw sizes you need for your specific project before buying.
Ratcheting mechanism
Ratcheting crimp tools require a complete compression cycle before releasing, preventing incomplete crimps. Non-ratcheting tools rely entirely on operator technique to complete each crimp - higher margin for error.
Jaw material
Stainless steel jaws resist corrosion and maintain calibration longer than chrome-plated jaws. Verify jaw material for any tool that will be used in wet or humid conditions.
Questions answered
Crimp tools compress a copper ring onto the fitting using outward-to-inward pressure. Clamp tools compress a stainless clamp using sideways squeezing. Both meet ASTM standards. Crimp rings are more commonly stocked at hardware stores, making repairs easier.
PEX crimp tools are designed for crimping copper rings on PEX tubing and fittings. For soldering or mechanical connections on rigid copper pipe, you need different tools (torch and solder, or press-fitting tools).
A go/no-go gauge verifies that each crimp ring is compressed to within specification. If the gauge's go side fits over the ring and the no-go side does not, the crimp is correctly sized. Without verification, under- or over-crimped connections can fail.
No. Quality crimp tools like Ridgid use interchangeable jaws for different diameters. You buy one tool body and the specific jaw sizes you need. Most residential work uses 1/2 and 3/4 inch.
