Two Crimpers Compared: PEX Kit and Modular Data Tool
As an Amazon Associate we earn from qualifying purchases.
iCRIMP and Klein Tools make crimpers for two different jobs, and the listings show that quickly. The iCRIMP kit is built for PEX plumbing connections with clamps, while the Klein VDV226-110 is a modular data cable crimper for RJ11, RJ12 and RJ45 connectors. This comparison sets their stated specifications against each other.
Both listings were checked on 2026-10-12. No other crimper listing matched this search, so the comparison covers these two products.
Quick answer
Choose the iCRIMP kit for PEX pipe connections from 3/8 inch to 1 inch, since its listing includes a cinch and remove tool, a PEX cutter and 30 clamps. Choose the Klein crimper for modular data and phone cable ends, since its listing covers 4, 6 and 8 position connectors. The two tools do not compete for the same job.

iCRIMP PEX crimping tool kit
The iCRIMP listing is a kit. The bullets say its tool meets ASTM 2098 and works with stainless steel clamps from any manufacturer for PEX connections from 3/8 inch to 1 inch. It can also cinch a single-ear hose clamp, as long as the ear fits inside the jaw opening.
The bullets describe a two-in-one cinch and remove tool, a steel body forged and wire-EDM cut at the jaw, and a ratcheting action with a self-release mechanism. The listing says the tool is factory adjusted and needs no calibration tool. The kit count is 32, which matches one cinch tool, one cutter and 30 clamps.
Klein Tools VDV226-110 modular data crimper
The Klein listing describes a ratcheting crimper that also strips and cuts for data cable. The bullets name RJ11 and RJ12 standard connectors and Klein RJ45 pass-thru connectors, and they say the tool crimps and trims 4, 6 and 8 position modular connectors.
The bullets describe a full-cycle ratchet that finishes a termination before it releases, a flush trim to the connector end face, and an on-tool wiring guide. The listing says it suits STP and UTP paired-conductor data cables. It weighs 14.4 ounces, and its specs list a cutting width of 15.5 centimeters.

How we chose these listings
The two research listings are the crimper products in this search. Two store listings were considered, a meter case and a non-contact voltage tester. Neither is a crimper, so both were left out.
Worked example: a 12-connection PEX job
Suppose a plumbing job needs 12 half-inch PEX connections. The iCRIMP kit lists 20 half-inch clamps, so it covers the 12 connections with 8 spares. A three-quarter-inch job with 12 connections would need more than the 10 listed clamps, so the kit would need a restock for that size.
The Klein crimper has no clamp count to compare, because it terminates cable ends rather than pipe fittings. Its listing covers 4, 6 and 8 position connectors, so a 6-position RJ12 end is inside its stated range.
What the listings do not say
The iCRIMP listing does not name a warranty period. The Klein specs give a cutting width of 15.5 centimeters next to a 6.1 inch length, and the listing does not explain the width figure, so it should be checked on the product page.
Neither listing reports a measured crimp strength or a field test result.
Frequently asked questions
Can the iCRIMP kit crimp data cable?
No. The listing describes a PEX crimping and cinching tool with clamps, not a modular data crimper for RJ connectors.
Which sizes does the iCRIMP tool cover?
The bullets say PEX connections from 3/8 inch to 1 inch, and the kit includes 1/2 inch and 3/4 inch clamps.
What connectors does the Klein crimper handle?
The listing says RJ11 and RJ12 standard connectors and Klein RJ45 pass-thru connectors, with 4, 6 and 8 position modular connectors.
Does either listing name a standard?
The iCRIMP listing names ASTM 2098. The Klein listing does not name a standard in its bullets or specs.
Conclusion
For PEX plumbing, the iCRIMP kit is the listing with the clamps, the cinch tool and a stated ASTM 2098 standard. For modular data cable, the Klein VDV226-110 is the listing with the connector range and the ratchet. Check the Klein cutting width and the clamp sizes on the live pages before ordering.
