Research on T-Junction as a separator of liquid-liquid flow is still of interest and developing. Some works evaluated certain geometries to obtain the best separation efficiency. The work to examine the separation behavior/characteristic of kerosene-water flow in a T-Junction at ratio of elbow radius to inlet diameter horizontal pipe (r/Dh) = 0.69 carried out is completed. The orientation of side arm is vertically right upward whilst the ratio at diameter of the flex glass tube is set at 0.7 (horizontal tube and vertical tube at 36 mm and 26 mms respectively). To lead kerosene to the side arm, the downstream valve set at 75% and 50% respectively. Downstream pressure, pressures difference at inlet-run arm (∆P1-2) and inlet-side arm (∆P1-3) and debit of kerosene and water in side and run arm are the variable at the research. Based on visualization and measurement at maximum flow separation efficiency at 88%, is gained at downstream pressure 104326 Pa, watercut 46%, Jmix = 0,31 m/s (Jw = 0,14 m/s and Jk = 0,17 m/s). The best separation result with Fk = 0,96 and Fw = 0,22 is gained at downstream pressure 104287 Pa, watercut 70%, Jmix = 0,56 m/s (Jw = 0,39 m/s and Jk = 0,17 m/s) and flow pattern at Stratified Bubble Interface (ST-BI)
