SMC's IDK series is a moisture control tube.  Condensation in a pneumatic system will cause operating failure and affect the life of pneumatic equipment.  The IDK prevents condensation in small cylinders, air grippers, and air operated valves by diffusing water vapor in the piping to the outside before it is condensed. 

• Applicable tubing O.D.: Ø 2 to Ø 6 mm
• Two shapes: linear and coil
• Tube effective lengths: 100 and 200 mm.
