The 5 Best PEX Crimp Tools — Full Reviews

1. iCrimp Ratchet PEX Cinch Tool with Removing Function — Best Overall

🏆 Best Overall

The iCrimp Ratchet PEX Cinch Tool earns the top spot on the strength of what’s actually in the box and how the tool works. It handles all standard US residential sizes from 3/8 to 1 inch and ships with clamps already included in the box: 20 pieces of 1/2-inch and 10 pieces of 3/4-inch stainless steel clamps, so you can start work straight out of the package. The ratchet mechanism is the defining feature here — it applies consistent, calibrated pressure on every crimp and eliminates the guesswork of manual tools, ensuring you hit the correct clamping force every time.

The built-in removal function is what sets this above comparable cinch tools. Instead of buying a separate removal tool when you need to cut out a bad joint or modify an existing PEX run, it is already integrated into the handle.

PEX Crimp Tool Buying Guide

Cinch Clamp vs Copper Crimp Ring — Key Differences

The most important decision when buying a PEX crimp tool is choosing your ring system — because the two types are not interchangeable. Cinch clamp tools (also called PEX cinch or clamp tools) use stainless steel bands that tighten around the PEX fitting with a ratchet or lever mechanism. They are quick to install and the removal function makes mistakes easy to fix. Copper crimp ring tools use ASTM F1807 copper rings that are compressed onto the fitting with a dedicated crimper. Copper crimp rings are the professional standard specified by most US plumbing codes and are the preferred method for inspected work. If you are unsure which system your fittings use, check the packaging — F1807 fittings are designed for copper crimp rings; standard PEX push fittings often work with either. If you would rather skip crimping altogether, our comparison of push-to-connect vs crimp fittings covers the trade-offs of that approach.

PEX-A vs PEX-B — Which Tool Do You Need?

PEX-A and PEX-B refer to the manufacturing method, not quality grades. PEX-A (such as Uponor/Wirsbo) uses an expansion fitting system — you expand the pipe end with a dedicated expansion tool and slide on a fitting ring. PEX-A does not use copper crimp rings or stainless cinch clamps. PEX-B is the most common type sold at US hardware stores (including most brands at Home Depot and Lowe’s) and it does use copper crimp rings or stainless cinch clamps. All five tools in this round-up are designed for PEX-B. If you are working with PEX-A, you need a dedicated PEX expansion tool — the crimp and cinch tools reviewed here will not work. Our full PEX-A vs PEX-B comparison covers how to tell which one you have, and see our guide on PEX vs CPVC pipe for a broader overview of pipe material choices.

What Sizes Do You Need — 1/2 vs 3/4 Inch

In US residential plumbing, 1/2 inch PEX is used for individual fixture supply lines (toilets, faucets, dishwashers) while 3/4 inch PEX is used for main distribution lines and hot water manifold runs. For a whole-home repipe, you need both sizes — tools like the KF CPTEC combo and the iCrimp angle head set cover both in a single purchase. For repairs on a specific fixture, 1/2 inch alone may be sufficient. The iCrimp Ratchet Cinch and iCrimp Kit cover a wider range from 3/8 to 1 inch, which is useful if you have 3/8-inch supply lines for refrigerators or ice makers.

Go/No-Go Gauge — Why It Matters

A Go/No-Go gauge is a simple pass/fail quality tool that checks whether your crimped ring is correctly compressed. The “Go” side should slide over a good crimp; the “No-Go” side should not. Without it, you are relying on visual inspection alone — which is unreliable for determining whether the ring is within ASTM F1807 dimensional tolerances. An under-crimped ring can cause a slow leak inside a wall that goes undetected for months. The KF CPTEC includes a gauge in the box; for the iCrimp crimp tools, it can be purchased separately at a low cost. Always use a gauge when doing inspected work or any connection inside a wall cavity.

PEX Adoption Across the US — Why This Tool Matters

In colder states like Minnesota, Wisconsin and Michigan where whole-home PEX repiping is common due to freeze damage on older copper systems, having a reliable crimp tool kit is as essential as any other plumbing tool. PEX has become the dominant pipe material for new residential construction across the Midwest and Northeast — its flexibility handles freeze-thaw cycles far better than rigid copper, and its lower material and labor costs have made it the standard specification for new builds from Ohio to Maine. Whether you are a contractor doing full repiping jobs or a homeowner completing a bathroom renovation, the right PEX crimp tool saves significant time and ensures code-compliant, leak-free connections throughout the system.

Frequently Asked Questions

Q: What is the difference between PEX crimp and PEX cinch clamp tools?

PEX crimp tools use copper ASTM F1807 rings that are compressed onto PEX fittings with a ratchet crimper. PEX cinch clamp tools use stainless steel bands that are tightened with a clamping mechanism. Both create secure, leak-free joints but they use different ring types that are not interchangeable. Copper crimp rings are the professional standard specified by most US plumbing codes and are required for inspected work in many states. Cinch clamps are faster to install and easier to remove, making them popular for DIY work and accessible repairs.

Q: Are PEX crimp tools interchangeable between brands?

Yes — ASTM F1807 copper crimp rings and the tools that install them are standardized by specification, not by brand. An iCrimp F1807 tool will correctly crimp rings from any ASTM F1807 compliant manufacturer. Similarly, stainless cinch clamp tools are interchangeable for the correct clamp sizes. The key is matching the tool type to the ring type: copper crimp tools work with copper F1807 rings, cinch tools work with stainless cinch clamps. Never mix the two systems on the same installation.

Q: Do I need a Go/No-Go gauge for PEX crimping?

For any work inside walls, ceilings, or any location that will be covered up after installation, a Go/No-Go gauge is strongly recommended. It is the only reliable way to confirm your crimp ring is within ASTM F1807 dimensional tolerances — visual inspection alone is not sufficient. An under-crimped ring can leak slowly inside a wall cavity for months before being detected, leading to water damage and mold. For accessible connections that can be visually monitored, a gauge is less critical but still good practice. The KF CPTEC in this round-up includes a gauge in the box; for other tools, one can be purchased separately at a low cost.

Q: Can I use a PEX crimp tool on PEX-A pipe?

No. PEX-A pipe (made by manufacturers like Uponor and Rehau) uses an expansion ring system — the pipe is expanded with a dedicated PEX-A expansion tool and the fitting ring contracts back onto the fitting as the pipe memory returns to its original diameter. PEX-A does not use copper crimp rings or stainless cinch clamps. All five tools reviewed here are designed for PEX-B (and in some cases PEX-C), which is the most common PEX type sold at US hardware stores. Check your pipe manufacturer’s specifications before purchasing any crimp tool.

Conclusion — Which PEX Crimp Tool Should You Buy?

For most homeowners and DIYers working with PEX-B on standard repairs and small installations, the iCrimp Ratchet PEX Cinch Tool is the easiest starting point — it includes clamps in the box, the removal function means mistakes are fixable, and the ratchet mechanism takes the guesswork out of crimp pressure. For copper crimp ring work or any inspected plumbing, step up to the iCrimp IWS-1807CN.
