High-priority model guide
The M12 FORCE LOGIC 2573-20 is Milwaukee's current compact press-tool platform. This guide separates the tool's general material capability from the more important question: which fitting systems, sizes and jaw/ring families are actually documented for the 2573.
Current model: 2573-20
Milwaukee's current product page identifies the M12 FORCE LOGIC press tool with ONE-KEY as 2573-20. The 2026 Press Tool Compatibility Matrix lists 2473-20 as the discontinued predecessor.
If you own a 2473, do not assume every current 2573 feature or kit description applies. Use the current matrix and the exact attachment part number for compatibility decisions.
Milwaukee positions the 2573 as a compact in-line press tool for copper, PEX, black iron, stainless steel and ACR applications. The current product information highlights one-handed in-line use, a 180-degree rotatable head, auto-cycle, a pre-press battery check, ONE-KEY reporting and a 37,000-press interval between service inspections.
Those are tool-level capabilities. They do not mean one jaw set covers all five material categories. Milwaukee's own product FAQ states that separate jaws are required for different materials, and the compatibility matrix maps the approved attachment family for each fitting system.
The values below are system-specific examples from Milwaukee's current matrix, not a promise that every fitting with the same nominal material and size is approved.
| Fitting system / application | Documented M12 2573 range | Attachment path | Important note |
|---|---|---|---|
| Viega ProPress / ProPressG | Up to 1-1/4 in. | M12 CTS-V jaws/rings for the applicable size; selected listed cross-brand compact jaws also appear in Milwaukee's matrix | Verify copper vs. stainless fitting line and the exact jaw/ring part number. |
| Viega MegaPress / MegaPressG | Up to 1 in. | M12 IPS-P jaws/rings | Do not extend the compact tool to larger MegaPress sizes simply because a larger jaw exists for another platform. |
| PEX crimp | Up to 1-1/2 in. in the current matrix | M12 PEX crimp jaws with size exclusions noted by Milwaukee | PEX crimp is not the same attachment family as PureFlow PEX Press. |
| ZoomLock MAX / >B< MaxiPro | Up to 1-1/8 in. | ZoomLock/MAXiPro jaws for M12 | Use the fitting-system jaw, not a plumbing CTS jaw that merely matches tubing OD. |
| RLS HVAC/R | 1/4 to 1-3/8 in. fitting-system range | Milwaukee matrix lists RIDGID RLS RJ Series jaws | Manufacturer-document conflict: RIDGID's current jaw instructions say these jaws do not work with other brands. Verify before use. |
For copper/CTS press systems such as ProPress, Milwaukee's matrix maps the M12 to CTS-V attachments. For MegaPress/IPS work, it maps the tool to IPS-P attachments. A 1-inch CTS jaw and a 1-inch IPS jaw are not interchangeable just because the size marking is the same.
This is one reason used-tool listings can be confusing. A bare 2573 may be a good purchase for someone who already owns the correct M12 attachment family, while a seemingly attractive kit may be poor value if its included jaws do not match the fitting system you actually install.
Milwaukee's compatibility matrix includes selected RIDGID Compact ProPress, PureFlow and other attachment catalog numbers in its cross-brand table. That is meaningful because it is manufacturer documentation rather than a forum anecdote or retailer claim.
But cross-brand documentation can also disagree. The clearest example currently in our data is RLS: Milwaukee's 2026 matrix lists RIDGID RLS RJ Series jaws for the M12 2573/2473, while RIDGID's current RLS jaw instruction sheet states that those jaws will not work with other brands of press tool. We do not convert one statement into an unqualified approval. The status remains UNKNOWN — VERIFY WITH MANUFACTURER until the conflict is resolved.
The M18 is not automatically the better tool, and the M12 is not automatically the better value. The right answer comes from your largest required system-specific connection and the attachments you already own.
The closest RIDGID comparison is a compact-series tool such as the current RP 251, not the larger RP 350. Both M12 2573 and RP 251 target compact professional press work and can cover common ProPress, MegaPress, PEX and ACR applications with their respective approved attachment families.
If you already own jaws or batteries, ecosystem cost can matter as much as the bare tool price. If you are starting from zero, compare the complete setup required for your actual fitting systems rather than comparing tool-only prices. The Press Tool Finder lets attachment ownership and battery platform influence ranking only after compatibility and capacity are satisfied.
Last technical verification: August 25, 2026. Installation instructions and current manufacturer compatibility documents control.
The current M12 FORCE LOGIC press tool with ONE-KEY is model 2573-20. Milwaukee’s 2026 compatibility matrix lists the older 2473-20 as discontinued.
Milwaukee’s current product information shows general copper capacity through 1-1/4 inches. For Viega ProPress and other specific systems, the exact approved jaw or ring family and system-specific size limit still need to be confirmed.
Yes, within Milwaukee’s documented range. The 2026 compatibility matrix lists the M12 2573 for Viega MegaPress and MegaPressG through 1 inch with the specified M12 IPS-P jaw or ring family.
No. Milwaukee states that M12 and M18 direct jaws are not interchangeable because the tool interfaces differ. Shared ring systems, where approved, still require the correct platform-specific ring jaw or actuator.
Milwaukee’s 2026 matrix lists selected RIDGID Compact ProPress jaw catalog numbers as compatible with the M12 2573 family. Cross-brand approval should still be checked against the latest matrix and the exact jaw part number before use.
The current manufacturer documents conflict. Milwaukee’s 2026 matrix lists RIDGID RLS RJ Series jaws for the M12 2573/2473, while RIDGID’s current RLS jaw instructions say those jaws do not work with other brands of press tool. PipeTradesTools.com therefore treats that combination as unknown and recommends verification with the manufacturers before use.
