• A minimum water flow rate of 100/mL per minute in a horizontal position and 140mL per minute in a vertical position is required to mobilize the ball
• Upper flow limit is in excess of 1 liter/minute
• Maximum working pressure is 10 p.s.i.g. (69 kN/m2)
• Dimensions: 30 x 57mm (1? x 2¼in) with two 23mm (0.9in) long tube extensions
