Products – Palm-sized compact gas source
NTG mini gas cylinders, sometimes called mini gas cartridges, are used for various applications in diverse fields. They are easy to handle because they are as small as they can be, and even fit into the palm of your hand. These mini containers, which are not restricted by the high-pressure gas safety laws in Japan*, can be filled with carbon dioxide, oxygen, nitrogen, helium, argon, LPG, and other compressed and liquefied gases**.
- *The cylinders or containers themselves are not restricted by the Japanese high-pressure safety law but the gases inside the cylinders are subject to the high-pressure law of Japan.
- **NTG does not manufacture N2O cylinders as Japanese law prohibits manufacturing and distributing N2O gas in disposable cylinders.

Made-in-Japan Quality
The mini gas cylinders and gas handling equipment, including regulators, are made at our Tsuga factory in Tochigi, about 100 kilometers from Tokyo. The factory has been certified as a producer of mini high-pressure gas cylinders with a capacity of less than 100cc by the High Pressure Gas Safety Institute of Japan, KHK*.
For more information about NTG’s quality, please see Quality Control.
Mini Regulators and Piercing Valves
– NR Series Regulators
All made at our regulator production facility in Tochigi, NTG regulators are extremely compact, highly functional and able to flexibly control the pressure of many types of gases.
By screwing a cylinder into the inlet port of a regulator, the cap of the cylinder is automatically pierced by a cut pin integrated inside the inlet port. The NTG cut pin is designed not to allow gas leakage during the puncturing process of a cylinder.
You can maximize the performance of these regulators by using them with our gas cylinders.

Safety Measures
NTG regulators are made with safety devices. A built-in rupture disc on the primary side and a safety release valve on the secondary side of a regulator function to protect against over-heating and over-pressure events.
