Diaphragm-type gauge isolator to protect pressure gauges from corrosive fluids.
The MTG series is a diaphragm-type gauge isolator. By installing it between the fluid and the pressure gauge, it protects the pressure gauge from corrosive or highly viscous fluids and prevents contamination of the fluid from the pressure gauge. In addition to the conventional model "Tough Guard," which has a proven track record, we have introduced the latest model "MTG series," which achieves a compact, lightweight, and low-cost design. The diaphragm features a two-layer structure (PTFE, FKM). ● Lightweight and compact design that can be installed in the middle of piping ● Material of the main body can be selected according to the fluid ● The wetted parts are free of metal and lubricating oil

Company information
Our company was founded in 1971 and has been introducing unique and excellent products from overseas to our customers in Japan. We handle over 10,000 items, including fittings, couplings, various valves, and check valves. Among these, we take pride in being a pioneer in the market for small plastic piping components manufactured by CPC in the United States, such as CPC couplings, which we have been proposing since 30 years ago when brass and stainless steel were the norm. These products are widely used in small devices across various fields, including general industry, healthcare, food and beverage, printing, and experimentation, due to their features of being "compact," "lightweight," and "offering a wide variety." Additionally, in the field of industrial air equipment, we have been supplying products focused on "cooling," "blowing," and "air transport" using compressed air, including the "Cryogenic Air Generator Kolder," to manufacturing sites across various sectors for many years. In recent years, we have also been focusing on new product development in different fields, including springs made from PEEK resin. In April 2018, as part of our new initiative to improve customer satisfaction in industrial piping components, we opened a satellite showroom in Odaiba displaying approximately 2,500 items.
