There are many different methods of fitting pipes together for drinking water and heating applications, and today we’re seeing more and more that customers are choosing to use press fittings as their “go to” method of joining these pipes.
Existing methods such as “threading”, “welding” or “soldering” can be time consuming and require specific skills. With press fittings, customers can fit two pipes together using a hydraulic tool and jaw in seconds, making it a quick and safe process.
Combine those benefits, with Hilti tool technology, such as Hilti Connect, our in-built method of checking the service history of the tool and jaws, and you can manage your press tools and pipe connection work in a productive and efficient way.
Our range of press tools and jaws can press up to 108 mm pipes, depending on the profile, covering a whole range of pipe pressing applications. Since we launched the tool in August last year, we’ve had loads of questions from our community on social media surrounding the pipe press process, the press jaws and about the tool itself; so, we’ve got our Product Manager for Cordless, Dean Murphy, to answer the top 9 questions…
Well our Hilti tools differ in press force, for example our NPR 19-A presses at 19kN whereas our NPR 32-A presses at 32kN press force. The press force will normally define the size of the pipe, with the smaller tool covering certain sizes and the larger tool being able to handle slightly larger sizes. This of course depends on the pipe system, and the correct jaw being used. We will also launch a third tool soon, enabling customers to press the larger sizes (typically greater than 77 mm) of pipe.
Our compact 22V 2.6Ah compact battery will provide enough energy for a typical day’s work. However, bear in mind that it is difficult to provide specific information on the number of operations per charge as these can vary greatly depending on pipe diameter, temperature and user behaviour.
Firstly, if you stop, but don’t press the release button, you can pull the trigger again and the NPR pipe press tool will continue pressing until the cycle is completed. Or if you hit the release button when the press operation has started, the tool will make a beeping sound and a red light will flash to warn the user that the press cycle is not completed.
Hilti NPR tools automatically retract when the press cycle is completed. But, let’s not forget that the only way for the customers to be sure all press fittings have been correctly pressed is by conducting a pressure test – this is a standard test in the industry that should be conducted on every pipe installation.
Our NPR PM are called mini jaws and that’s because they’re compatible with the NPR 19-A tool. Whereas, the Hilti NPR PS jaws are called standard jaws as they are compatible with the NPR 32-A tool. Please bear in mind, that you can’t exchange them as they are specifically designed for each tool.
A “profile” is the specific shape of the inside of the jaw, and this will match with certain pipe manufacturers fittings. Therefore, it is key that the correct jaw profile is chosen for the pipe fittings being used. Each manufacturer will dictate which profile of jaw is needed and which jaw and tool is suitable.
We recommend sending the NPR 19-A and NPR 32-A pipe press tools in for a service inspection every 15,000 cycles or once every year.
Good news! Both the Hilti NPR tool and the NPR PM and PS jaws are compatible with Hilti Connect. Inside the tools there’s an NFC chip close to the battery connection which talks to the Hilti Connect app on your phone or tablet. The jaws, have a tag that enables the usage with both Hilti Connect and Hilti ON!Track. For instance, Hilti Connect allows you to proactively track service dates for all your jaws, helping you to ensure that you never miss a service date.
