“Press Jaws & Rings Compatibility Guide: Fit Milwaukee, RIDGID & DEWALT Tools”

Press Jaws & Rings Compatibility Guide

You bought the press tool. Now the question that actually costs money: which jaws and rings fit it? Get this wrong and you’re shipping a $90 jaw back or, worse, forcing a fit that fails under pressure.

This guide covers ZUPPER’s jaw and ring ecosystem and where it lines up with the big names — Milwaukee M18 FORCE LOGIC, RIDGID RP, and DEWALT DCE200.

Standard (32 kN) vs Compact (24 kN)

Press tools come in two force classes, and jaws are not cross-class compatible:

Standard press tools (~32 kN / 7,200 lbs) — drive jaws and rings up to 2″ on copper, stainless, and carbon steel.
Compact press tools (~24 kN / 5,400 lbs) — lighter, for 1/4″–1 1/8″ HVAC and ACR copper work.

Always match jaw class to your tool’s rated force.

ZUPPER Jaw & Ring Lineup

Product	Class	Covers	For
32-R14 Standard Press Jaws	32 kN	1/4″–1 1/8″	RLS ACR copper (HVAC/refrigeration)
24-R14 Compact Press Jaws	24 kN	1/4″–1 1/8″	RLS ACR copper
32-VMP MegaPress Jaws	32 kN	1/2″–1″ / 1/2″–2″	Carbon steel (MegaPress)
R8 / R9 ProPress Ring Kits	32 kN	1/2″–2″	Copper ProPress, tight/angled spots

Cross-Brand Compatibility

ZUPPER standard jaws and rings are compatible with major US-brand 32 kN tools, including:

Milwaukee M18 FORCE LOGIC (DCE-class presses)
RIDGID RP 340 / 350 / 351
DEWALT DCE200
ZUPPER’s own PZ-3240, PZ-1550, EB-1550

Compact jaws fit ZUPPER and US-brand 24 kN compact tools.

Rule of thumb: same force class + same fitting standard = compatible. When in doubt, check the kN rating stamped on your tool.

How to Choose

1. Know your pipe. Copper/Stainless → ProPress jaws/rings. Black iron → MegaPress. ACR/HVAC copper → RLS jaws.

2. Know your size range. Don’t buy a 1/2″–1″ set if you regularly run 2″ drops.

3. Know your tool class. 32 kN or 24 kN — this decides everything.

FAQ

Will ZUPPER MegaPress jaws fit my Milwaukee? Yes — 32-VMP jaws are built for 32 kN standard tools including M18 FORCE LOGIC.

Can compact jaws go on a standard tool? No. The force class must match or the joint won’t seat correctly.

Best Cordless Press Tools 2026: ProPress, PEX & MegaPress Compared

A cordless press tool turns a 20-minute soldered joint into a 4-second squeeze. Whether you’re setting copper ProPress, black-iron MegaPress, or PEX connections, the right tool pays for itself in the first week of jobs.

We compared the brands pros actually argue about — Milwaukee, RIDGID, DEWALT, VEVOR — and where ZUPPER fits if you want pro-grade results without the big-box markup.

What a Press Tool Actually Does

Instead of heat and solder, a press tool uses hydraulic or electro-mechanical force to permanently compress a fitting onto pipe using approved press jaws or rings. No flame, no flux, no hot work permit. That’s why press has taken over commercial and residential plumbing.

ProPress = copper and stainless pipe fittings.
MegaPress = carbon steel pipe fittings.
PEX press/crimp/expansion = plastic pipe, covered in our separate PEX guide.

How We Evaluated

We weighed four things that matter on the job: pressing force (kN), jaw/ring ecosystem, battery platform, and total cost of ownership.

The Contenders

Milwaukee M18 FORCE LOGIC

The industry benchmark. Huge jaw library, excellent ergonomics, deep M18 battery ecosystem. The cost is the cost — tools and jaws are premium-priced.

RIDGID RP Series

Trusted by trades for decades. Rugged, widely supported, strong press force. Pricing sits near Milwaukee.

DEWALT 20V MAX Press

Familiar to crews already on the 20V platform. Solid performance, good if you’re standardized on yellow.

VEVOR

The budget disruptor — aggressive pricing and “works with major brand jaws” messaging. Build quality and support are the trade-off.

ZUPPER

Professional-grade 18V press tools and a full jaw/ring ecosystem at a value price. Compatible with major US-brand compact and standard jaws (Milwaukee M18 FORCE LOGIC, RIDGID RP, DEWALT DCE200), so you’re not locked into one wall of jaws.

Comparison Table

Brand	Force Class	Battery	Jaw Ecosystem	Value
Milwaukee M18	Standard/Compact	M18	Largest	Premium
RIDGID RP	Standard/Compact	RIDGID	Large	Premium
DEWALT 20V	Standard	20V MAX	Medium	Mid
VEVOR	Compact	VEVOR	Cross-brand claim	Budget
ZUPPER	24kN / 32kN	18V	Cross-brand compatible	Best value

Buying Guide

1. Match force to pipe. Compact (24 kN) covers 1/2″–1 1/8″ HVAC/ACR. Standard (32 kN) handles up to 2″ copper and carbon steel.

2. Check jaw compatibility. If you already own Milwaukee/RIDGID/DEWALT jaws, a cross-compatible head saves you hundreds.

3. Count cycles. Look at presses per charge if you’re off-grid or far from outlets.

ZUPPER Lineup

Compact ProPress Kit (PZ-2430 / SL-24303) — 18V, 1/2″–1 1/4″ copper jaws.
Standard ProPress Kit (PZ-3240 / ZEP-1550) — 18V, 1/2″–2″, 6 jaws + charger.
MegaPress Jaws & Rings (32-VMP) — carbon steel, 32 kN.
ProPress Ring Kits (R8/R9) — angle rings for tight spaces.

FAQ

Are ZUPPER jaws compatible with Milwaukee? ZUPPER standard jaws are compatible with 32 kN tools including M18 FORCE LOGIC, RIDGID RP, and DEWALT DCE200; compact jaws fit 24 kN tools.

Which is better, press or crimp for PEX? That’s a different question — see our PEX Crimp vs Expansion guide.

“PEX Crimp vs Expansion: Which Connection Method Should You Choose?”

PEX Crimp vs Expansion: Which Connection Method Should You Choose?

If you’re running PEX for a plumbing, hydronic heating, or water-heater project, you’ll hit the same fork in the road every pro does: crimp or expansion? Both make permanent, leak-resistant connections without solder or open flame — but they work differently, cost differently, and suit different jobs.

This guide breaks down the two methods in plain terms so you can pick the right tool (and the right PEX) before you’re standing in a crawl space with a deadline.

What Is PEX Crimping?

Crimping uses a copper crimp ring (or a stainless steel clamp ring on some systems) slipped over the pipe and fitting, then compressed with a crimp tool until the ring bites into the PEX.

Works with PEX-B (and PEX-A on certain certified systems) using copper rings.
Tooling is compact, lightweight, and relatively inexpensive.
Connection is immediate — no waiting for the pipe to relax.
Conforms to ASTM F1807 for cold-expansion and standard crimp fittings.

ZUPPER’s cordless crimp kit (MP-1930) crimps 1/2″, 3/4″, and 1″ PEX-B copper rings in about 2 seconds per joint, with up to 400 cycles per charge.

What Is PEX Expansion?

Expansion uses an expansion tool to stretch the end of PEX-A pipe, slide on a fitting, and let the pipe shrink back for a tight, full-flow seal. There are no rings to crimp.

Exclusive to PEX-A pipe (Uponor/Wirsbo, Apollo, SharkBite EVOPEX, etc.).
Delivers the largest internal diameter of any PEX connection — better flow, lower pressure drop.
More freeze-resistant: PEX-A “memory” lets an expanded joint recover after a freeze better than crimped joints.
The tool is bulkier and each joint takes a few seconds longer, but the result is a smooth, unobstructed path.

ZUPPER’s 18V PEX-A expansion tool (ME-1225) ships with 1/2″, 3/4″, and 1″ auto-rotating heads and 70+ expansions per charge.

Crimp vs Expansion: Side-by-Side

Factor	Crimp (PEX-B)	Expansion (PEX-A)
Fittings	Brass + copper ring	Brass/PEX-A fitting, no ring
Flow	Slightly reduced at joint	Full-bore, maximum flow
Freeze resistance	Good	Best (PEX-A memory)
Tool cost	Lower	Higher
Tool size	Compact	Larger
Speed per joint	Fast (~2s)	Slightly slower
Best for	Tight spaces, budget jobs	Whole-home, high-flow, cold climates

Which Should You Choose?

Choose crimp if you want the lowest tooling cost, work in tight spaces, or already stock PEX-B. It’s the workhorse for remodels and repairs.
Choose expansion if you’re doing whole-home repipes, live in a freeze-prone region, or want the best possible flow and the smoothest interior bore.

Either way, buy the tool that matches your pipe — crimp rings won’t work on PEX-A, and expansion heads won’t fit PEX-B.

ZUPPER Options

PEX Crimp Tool Kit (MP-1930) — 18V cordless, ASTM F1807, 1/2″–1″ copper rings. Shop the PEX Crimp Tool Kit (MP-1930)
PEX-A Expansion Tool Kit (ME-1225) — 18V cordless, 1/2″–1″ heads, PEX-A only. Shop the PEX-A Expansion Tool Kit (ME-1225)

FAQ

Can I use a crimp tool on PEX-A? Only with certified crimp rings and fittings rated for PEX-A; most pros keep crimp for PEX-B and expansion for PEX-A.

Is expansion better than crimp? For flow and freeze recovery, yes. For cost and compactness, crimp wins. Neither is “wrong.”

Do I need special fittings? Crimp needs brass fittings + copper rings. Expansion needs PEX-A expansion fittings — no rings.
