Water cooling and various liquids one-touch fittings / non-drip couplings
● No liquid leakage ● Three safety features available as options ● Usable up to 315℃
The Sain water and various liquid non-drip coupling can be connected with a simple one-touch action (just push the nipple into the coupling), and thanks to its unique valve design, there is absolutely no liquid leakage during disconnection. Additionally, if safety is a concern, three types of safety features are available as options: 1. Color coding for easy identification of liquids and pressure, 2. Key codes to prevent incorrect port connections, and 3. A safety lock mechanism to prevent unexpected disconnections. By choosing Calretz as the sealing material, it can be used at temperatures up to 315°C. Furthermore, upon request, couplings and nipples without built-in valves can also be used as standard.

Non-drip screw coupling for data center CDU
For connecting the cooling water circulation system of the data center! OCP standard threaded non-drip coupling.
The Large Quick Connector (LQC) for data centers was developed for cooling water circulation devices (CDU) within the Open Compute Project (OCP) initiative. We are one of the manufacturers that developed this standard. The screw connect method of the OCP LQC is more user-friendly than the push-to-connect type quick connect couplers and can be connected even under a maximum operating pressure of 0.5 MPa. Because it is an open standard, any manufacturer's product can be connected as long as it adheres to the LQC standard specifications. Our LQC couplings comply with the standard and exceed its specifications.

Smart Flow Drive Lake Coupling
TEAM SPEC / Compliant with STANAG 3756, no liquid leakage. Coupling for liquid transfer.
Smart Flow Drive Lake Couplings are designed to support safe, efficient, and environmentally friendly fluid transfer in harsh environments where safety is a priority. With minimal components and no need for additional valves, they allow for leak-free connections and disconnections, saving both time and costs. They are commonly used in AdBlue distribution, road and rail tankers, offshore applications, marine bunkering, and IBC filling. Smart Flow Couplings feature a safety factor of five times the operating pressure of 2.5 MPa, regardless of size or material. This is unique in the industry, and for applications requiring higher pressures, you can choose Smart Flow aluminum units as a lighter and more cost-effective alternative to competitors' stainless steel units. Compliance with TEAM SPEC and STANAG 3756 standards ensures compatibility with products from other manufacturers. Additionally, FDA-approved O-rings are available to meet the stringent safety and hygiene standards required for use in food and beverage manufacturing.
