Key Features
M18 Press Tool FitBuilt specifically for Milwaukee M18 FORCE LOGIC press tools, this jaw kit gives HVAC and refrigeration techs the right interface for RLS press fitting work without adapting or guessing.Inline AccessThe inline jaw design helps you get into tighter mechanical rooms, rooftop runs, and crowded pipe chases where bulky head shapes slow you down.Faster Than BrazingWhen paired with compatible RLS HVAC/R braze-free press fittings, these press jaws can deliver connections up to 60% faster than brazing while avoiding nitrogen purges, fuel gas, and silver solder.
Overview
The Milwaukee 49-16-2662R 1/4 in. – 1-1/8 in. RLS Press Jaw Kit for M18 FORCE LOGIC Press Tools is a seven-piece press jaw accessory kit built for HVAC and refrigeration installers working with RLS braze-free press fittings. This is a press jaw kit designed for installing RLS HVAC/R braze-free press fittings on ACR tube and line sets. Model Number 49-16-2662R. If you already run an M18 FORCE LOGIC press tool and want a flame-free way to make high-pressure HVAC and refrigeration connections, this is the dedicated jaw set made for that job.
What matters here is not just the size range, but what that range covers on the job. This kit includes seven jaws from 1/4 inch through 1-1/8 inch, which lines up with common ACR tube and line set work. That gives you one organized kit for service calls, retrofit work, and new installs instead of piecing together individual jaws. Milwaukee also states these jaws are compatible with RLS HVAC/R braze-free press fittings and ACR tube and line set applications, so the use case is clear and trade-specific.
The big advantage is speed and process control. Milwaukee positions these jaws as a flame-free alternative to traditional brazing, with installations up to 60% faster versus brazing. In real terms, that means less setup, fewer consumables, and fewer steps around nitrogen purging, combustible gases, and silver solder. For contractors working in occupied buildings, finished spaces, or rooftops where open flame creates extra hassle, that is a practical gain, not a brochure claim.
Milwaukee also built these jaws around access. The inline design is there for a reason: HVAC and refrigeration work rarely happens on an open bench. You are usually reaching into line sets, mechanical rooms, above ceilings, or around existing pipe and equipment. An inline profile helps the press tool approach the fitting more directly, and the spring-loaded design helps with easier alignment to the fitting before the press is made. That is the kind of feature that saves time every connection, especially when you are working one-handed or from an awkward position.
Durability matters with press accessories because the jaw takes the abuse. Milwaukee calls out durable steel jaws for long service life, which is exactly what you want in a kit that will move from van to roof to mechanical room. At 36.5 pounds for the full seven-piece kit, this is not a light accessory set, but that weight makes sense for a complete steel jaw package in a carry case. This is a kit meant to live with your press tool setup and show up ready for real installation work.
Compatibility is straightforward. These jaws are for use with Milwaukee M18 FORCE LOGIC press tools. They are not a standalone press tool and they are not a general-purpose plumbing jaw set for every fitting system. They are purpose-built for RLS HVAC/R braze-free press fittings, which is exactly why they make sense for contractors who want a dedicated solution for ACR work.
Who should buy it? HVAC installers, refrigeration techs, and mechanical contractors already invested in the Milwaukee M18 FORCE LOGIC platform. If your work includes copper ACR tube, rooftop condensing units, refrigeration lines, or high-pressure HVAC connections, this kit saves time and simplifies the install process. If you do not own a compatible M18 FORCE LOGIC press tool or you are not using the RLS fitting system, this is the wrong accessory. But for the crew it is built for, it is a serious productivity piece.
Press in Tight Mechanical Spaces
This kit is built for the kind of access problems HVAC crews deal with every day. The inline jaw design helps the tool approach fittings in packed mechanical areas without the awkward angles that slow down the press.
- Inline design is made for better access around installed tubing and equipment
- Optimized for one-handed pressing with M18 FORCE LOGIC press tools
Make Clean Connections Without Brazing
For crews moving away from open-flame work, this setup streamlines the connection process. Milwaukee states these jaws provide up to 60% faster installations versus brazing when used with compatible RLS fittings.
- Works with RLS HVAC/R braze-free press fittings
- Eliminates the need for nitrogen purges, combustible gases, and silver solder required by traditional brazing methods
Built Around Real HVAC Installation Work
This is not a generic accessory set. It is aimed squarely at ACR tube and line set installation, which makes it a strong fit for rooftop work, refrigeration piping, and high-pressure system installs.
- Compatible with ACR tube and line set applications
- Designed for high-pressure HVAC and refrigeration system installations
Full Seven-Jaw Kit, Ready to Organize
Instead of buying jaw sizes one at a time, this kit packages the common range in one case so your crew can show up with the sizes needed for ACR work already together.
- Includes seven jaw sizes from 1/4 inch to 1-1/8 inch
- Packaged as a complete kit for M18 FORCE LOGIC press tool users

Pro Tip
Match the jaw size to the tube size before you get on the roof or into the mechanical room, then use the spring-loaded jaw to seat squarely on the fitting before cycling the tool. It is a small step, but it helps speed up repetitive connections and keeps the press setup cleaner in tight spots.
