The quick coupling set without valve, consisting of a socket and plug with hose end, is designed for demanding applications such as inkjet printing systems, medical environments involving blood transfer, cooling fluid circulation, or gas chromatography. Its innovative connection method, based on twisting the two elements together, ensures a secure and reliable fit while allowing the hose to rotate slightly during operation. This prevents unwanted twisting, reduces mechanical stress, and minimizes the risk of accidental disconnection, ensuring smooth and uninterrupted processes. Manufactured from durable acetal and sealed with an NBR O-ring, the coupling guarantees long-lasting performance even under intensive use. With a nominal size of DN 1.2 mm, a total length precisely adapted to system requirements, and resistance to working pressures up to 6.9 bar, it provides both safety and efficiency. The wide operating temperature range from -40°C to +82°C makes it suitable for diverse industrial and laboratory conditions. For additional flexibility, versions with integrated valves and in elegant black color are also available, offering tailored solutions for specialized applications. This coupling is the perfect choice for professionals seeking reliability, ease of use, and advanced functionality in fluid and gas handling systems.
