STAUBLI Fluid Connectors Thermal management - DAG automatic clean break couplings DAG

DAG automatic quick-release couplings are compact, stainless steel, non-drip connectors for liquid-cooling circuits in data centers and high-performance computing, featuring a flat-face design that ensures zero fluid loss and environmental cleanliness. They include a one-hand automatic locking system with front O-ring seals and colored markings (blue/KR, red/KB) for circuit identification. The couplings operate with ethylene-propylene (EPDM) seals rated for temperatures from -20 to +150 °C and a maximum pressure of 16 bar. Flow rates are 2.12 l/min for DAG 03, 8.48 l/min for DAG 06, and 19.09 l/min for DAG 09 at 5 m/s fluid velocity. They are designed for glycol water and cooling liquids, but EPDM seals must not contact mineral-based fluids.
