A metal semi-large model that further evolves the non-spill technology, which minimizes liquid dripping during coupling disengagement and air intrusion during connection to the utmost limit.

The LQ6 series (for liquid cooling applications) features a sleek metal design and covers a temperature range up to 115°C, making it applicable for various liquid cooling uses, from device installation to on-site equipment. Additionally, the main unit adopts a well-established thumb latch (button type) that allows for easy and quick one-handed operation.

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.
