At NAKK, we have established a "Leak Test Lab" to help you gain a deeper understanding of leak testing. By sending us samples in advance, we will select the testing method, collect data, and report the optimal setting time and detectable leak amounts. We will assist you in introducing the most suitable method to your test line. 【Common Issues】 - Already using a leak tester, but it is unstable. - Need to perform leak tests but do not know how. 【What You Can Experience】 - Selection of leak testing methods for brought-in work - Data collection with samples - Technical guidance - Training - Suggestions for optimal test line introduction methods 【Cost】 Basically free of charge. *We will only charge necessary expenses for items that require fabrication, such as sealing jigs.

Many of the items, facilities, parts, and machines necessary for production that we use in our daily lives must not allow their contents to leak, either internally or externally. For example, if there is a leak in gas or water piping components, it is a waste of resources and can sometimes be dangerous. Let's make good use of leak testers to prevent "leaks"! == New Product == Differential Pressure Leak Tester NLT-330 It detects leaks with high precision by comparing measurements with a leak-free master. Its compact design makes it easy to operate. You can preset up to ten different conditions, allowing for easy recall based on the workpiece. Highly recommended for beginners in leak testing!

The leak tester applies pressure or vacuum to finished products and components, and electrically detects pressure changes in the event of a leak using a highly sensitive differential pressure sensor. Since leaks are detected electrically, it is easy to quantify and automate leak testing, which was not possible with traditional visual inspection methods. The elimination of the drying process and the removal of individual differences in detection capability are also significant advantages. We provide testing machines that are particularly suitable for airtightness testing of automotive parts, gas/water supply components, mobile phones, digital cameras, and medical devices. We will verify the testing methods that match your testing conditions at the leak test lab. *For examples of leak tester implementations, please visit our website.

You can connect directly to the male thread you want to connect to, completing the sealing process. The work of wrapping sealing tape and tightening with tools, which was required every time until now, will no longer be necessary. It features a more compact design than the one-touch type. *Note that separate fluid supply and exhaust will be required. ■ Features 1. You can tighten it by hand (no tools needed) to the male thread you want to connect. 2. Sealing occurs when the packing contacts the end face of the male thread. 3. It is excellent in waterproof, water-resistant, and chemical-resistant properties. *You can download the catalog from the download button below.

The rear end of the one-touch coupler locks and seals by being pushed into the male thread work side. 2. The release mechanism at the rear end of the one-touch coupler is slid to unlock. 3. It is also excellent in waterproof, water resistance, and chemical resistance. *You can download the catalog from the download button below.

It was very difficult to set the workpiece using a robot in a leak test where a clamping mechanism is essential to seal the workpiece. However, by using a six-axis robot, we were able to gain a certain degree of freedom in movement, which allowed us to resolve the issue. Additionally, for the loading and unloading, we use air cylinders to keep the slide end in its original position, which results in a design that minimizes displacement in the Y (X) axis. We are moving away from conventional semi-automatic machines (manual workpiece setting) and achieving online automation.

The NLT-130 is a direct pressure air leak tester designed with essential functions prioritized for cost-effectiveness. - Recommended for those who want to implement it as cheaply as possible. - Currently conducting all direct pressure air leak tests manually. It features automatic functions from pressurization to measurement and OK/NG judgment after pressing the start button. The displayed value only shows the pressure within the measurement volume (including piping). *No zero reset during measurement transition. 【Features】 ■ Thorough cost performance ■ No difficult adjustments required without a master tank ■ Compact design for easy operation

In the automotive industry, performance evaluation of components is essential to ensure product safety and reliability. Particularly for critical parts such as engines, transmissions, and brakes, accurate measurements of leaks, pressure, and flow are crucial for maintaining product performance. Inadequate measurements can lead to component failures or performance degradation. Our comprehensive catalog of measuring instruments covers industrial measuring devices, including leak testers, and supports the performance evaluation of automotive parts. 【Usage Scenarios】 - Leak testing of engine components - Waterproof testing of electronic components 【Benefits of Implementation】 - Improvement in product quality - Reduction of defective products - Increased customer satisfaction

In manufacturing line leak tests and pressure tests, quick and reliable connection work is required. Traditionally, labor-intensive tasks such as wrapping seal tape and tightening with tools were necessary, which not only extended work time but also posed a risk of poor connections. Our one-touch coupler (for male threads) addresses these challenges and contributes to the efficiency and standardization of leak testing. 【Usage Scenarios】 - Pressure supply or sealing during air leak testing - Fixture exchange during differential pressure testing or master switching - Submersion testing - Bubble confirmation testing 【Benefits of Implementation】 - Reduction of seal tape wrapping and tool tightening tasks - Shortened work time and improved production efficiency - Stabilization of quality through standardized connection work - Structure with excellent waterproof, water-resistant, and chemical-resistant properties
