CPC coupling

CPC couplings are top-class couplings for plastic tubes with over 30 years of history.

CPC couplings are products that excel in both functionality and design, featuring a precision hose barb integrated with the main body, a shut-off valve that blocks the flow path when disconnected, and a push-button thumb latch that allows for quick connection and disconnection. The unique thumb latch mechanism from CPC enables speedy and reliable operation without requiring specific skills from the operator. Additionally, the ability to freely choose whether or not to include a valve that blocks the flow path during disconnection makes it ideal for applications where liquid spillage is undesirable. The wide range of sizes, designs, and selectable materials has garnered strong support across various fields, including medical and beverage industries.

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.
