The CEJN NON DRIP quick coupling plug is a high-performance solution for safe and efficient fluid transfer, designed to handle water, oil, chemicals, and more with maximum reliability. Its flat contact surfaces ensure leak-free operation by minimizing fluid loss and preventing air inclusion, while also making it easy to keep the coupling clean and hygienic. Available in multiple configurations—free flow, one-sided shut-off, or fully leak-free two-sided shut-off—this versatile system adapts to a wide range of applications. Protective caps safeguard the connection from dirt and contaminants when disconnected, extending the product’s service life. For enhanced safety and process control, the couplings can be color-coded in green as standard or in optional colors such as black, blue, red, white, and yellow, while key coding with grooves and protrusions guarantees correct and secure connections. Manufactured from durable nickel-plated brass and equipped with sealing options in NBR, Viton, or EPDM, the coupling ensures long-lasting performance under demanding conditions. With a working pressure of up to 20 bar and an impressive operating temperature range from -15°C to +205°C, it delivers outstanding reliability and flexibility across diverse industrial environments.
