What Is a Plumbing Press Tool?
A plumbing press tool is a powered or hydraulic tool that permanently forms a compatible press fitting around a pipe. The tool applies a controlled pressing force through the correct jaw, creating the mechanical connection specified by the fitting manufacturer.
Unlike welding, press-fit joining does not require an open flame or hot-work process. This can make press-fit systems particularly useful where hot work is undesirable or where pipework needs to be installed or modified quickly.
A plumbing press tool is also commonly called a plumbing crimping tool, pipe press tool or pressing tool. The terminology varies between manufacturers and trades, but the important consideration is always compatibility between the tool, jaw, pipe and fitting.
Press Fit Tools vs Welding
Press-fit pipe systems provide a different way to join pipework without welding or soldering. Instead of heating the joint, the fitting is mechanically pressed onto the pipe using the manufacturer's specified pressing tool and jaw profile.
| Press Fit | Traditional Welding |
|---|---|
| Mechanical pressing process | Thermal joining process |
| No naked flame at the joint | Uses heat and an open arc/flame depending on the process |
| No welding equipment required | Requires welding equipment and appropriate controls |
| Consistent pressing cycle when the correct tool and jaw are used | Joint quality depends on welding process and workmanship |
| Well suited to repetitive pipework assembly | Can require more preparation and hot-work controls |
Press-fit systems can significantly reduce joining time compared with conventional welding in suitable applications. The actual time saving depends on pipe size, system design, access, preparation and the installation environment.
Klauke Press Tools
Klauke press tools are professional pressing tools designed for plumbing and heating applications. Klauke's plumbing range includes radial pressing tools, pressing jaws, interchangeable dies, pressing chains and related accessories.
Air Energy supplies Klauke press tools for compatible press-fit applications. Tools are supplied in a carry case with battery and charger, while jaws are selected separately to suit the required application.
Klauke Pressing Jaws and Accessories
The pressing jaw is an important part of any press-fit system. The jaw profile and size must match the fitting manufacturer's requirements.
Klauke also offers pressing chains and accessories for larger pipe sizes and specific applications. For example, Klauke's HP pressing chains are available for compatible stainless steel and steel systems up to 108 mm, depending on the system and application.
Novopress Press Tools
Novopress press tools are professional pressing machines used across plumbing, heating, air conditioning and industrial pipework applications. Air Energy supplies several Novopress models, from compact tools for smaller pipe sizes through to heavy-duty equipment for large-diameter metal pipe.
Novopress ACO103
The Novopress ACO103 is a compact cordless pressing tool designed for smaller pipe sizes. Novopress lists a pressing range of up to 35 mm for metal pipe and up to 40 mm for plastic systems.
Novopress ACO203
The Novopress ACO203 is a cordless pressing tool for a broader range of pipe sizes. Depending on the compatible contour and system, Novopress lists metal pressing up to 54 mm for M-contour and up to 108 mm for V-contour, with plastic systems up to 110 mm.

How Does a Plumbing Crimping Tool Work?
A plumbing crimping tool uses a controlled pressing force to deform a compatible press fitting around the pipe. The fitting and pipe are designed to work together so that the completed joint provides the required mechanical connection and seal.
Typical Press-Fit Process
- Cut the pipe. Make a clean, square cut using the appropriate pipe cutting tool.
- Deburr the pipe. Remove sharp edges and any debris that could damage the fitting seal.
- Check the insertion depth. Use the appropriate depth gauge where specified.
- Insert the pipe. Push the pipe fully into the fitting.
- Select the correct jaw. The jaw profile and size must correspond with the fitting system.
- Position the tool. Place the jaws correctly around the fitting's pressing area.
- Complete the pressing cycle. Activate the tool and allow the complete manufacturer's specified cycle to finish.
- Inspect the joint. Check the completed connection before putting the system into service.
The exact process can vary between pipe and fitting manufacturers. Always follow the installation instructions for the specific press-fit system.
Choosing the Right Press Fit Tool
Choosing a press fit tool is not simply a matter of choosing the largest or most powerful machine. The tool needs to be compatible with the pipe, fitting and pressing profile being used.
1. Pipe Material
Identify whether you are working with stainless steel, carbon steel, copper, plastic or another compatible pipe material.
2. Pipe Diameter
Check the full range of pipe sizes that need to be pressed. A compact tool may be ideal for small-diameter pipe, while larger industrial pipework may require a heavier-duty tool and pressing chain.
3. Jaw Profile
The pressing profile is critical. Do not assume that a jaw from one press-fit system is automatically compatible with another.
For Europress applications, the required pressing profile and compatible tool configuration should be confirmed before purchasing.
4. Access
If you are working in plant rooms, ceiling spaces, service areas or other restricted locations, tool size, weight and head configuration can make a significant difference.
5. Battery Platform
For cordless tools, consider the battery platform, charging requirements and the number of presses expected during a typical work period.
6. Pipe Size and Pressing Force
Larger pipe requires tools and accessories designed for the required pressing force. For example, the Novopress ACO403 provides 120 kN of piston force and is designed for metal pipe from 76.1 to 168.3 mm.
Press Tools for Stainless Steel Pipe
Stainless steel press-fit pipe systems are widely used where corrosion resistance, hygiene, durability and a clean installation process are important.
A compatible plumbing press tool can join stainless steel pipe and press fittings without welding the joint. This can be particularly useful in compressed air, industrial services, food and beverage, water and other applications where the fitting system has been designed for press-fit installation.
Air Energy supplies Europress stainless steel pipe and fittings in 304 and 316L stainless steel, together with compatible press tools and accessories.

Press Tools for Carbon Steel Pipe
Carbon steel press-fit systems provide another alternative to traditional welded pipework for compatible applications.
As with stainless steel, the press tool, jaw profile, pipe and fitting must all be compatible with the manufacturer's specifications.
Press-fit carbon steel can be useful in industrial pipework where reducing hot work and improving installation speed are important considerations.
M Profile and V Profile Pressing Jaws
M profile and V profile are different pressing contours used by press-fit systems. They should not be treated as interchangeable simply because they look similar.
The correct jaw or pressing chain depends on the fitting manufacturer, fitting design, pipe material and pipe size.
For Europress, always confirm the required pressing profile before selecting your press tool jaws.
Common Plumbing Press Tool Mistakes
Using the Wrong Jaw
The wrong jaw profile can produce an incorrect press. Always use the jaw specified for the fitting system.
Using the Wrong Pipe Size
Check the pipe and fitting dimensions before pressing. A tool being physically capable of closing around a fitting does not automatically make it suitable for that fitting.
Not Deburring the Pipe
Sharp edges can damage seals during assembly. Prepare the pipe according to the fitting manufacturer's instructions.
Not Checking Insertion Depth
The pipe needs to be correctly inserted into the fitting before pressing. Use the specified depth mark or gauge where required.
Stopping the Pressing Cycle
Allow the press tool to complete its specified cycle. Do not interrupt the operation unless the manufacturer's instructions specifically require it.
Mixing Press Systems
Press tools, jaws, pipe and fittings are not universally interchangeable. Confirm compatibility before combining components from different manufacturers or systems.
