These plastic Flexible Coolant Pipes have been primarily used to spray refrigeration or washing fluid for machine tools but, thanks to their articulation, they can be used in a multitude of different ways as well. We use them as extra arms for our third hand.
The coolant pipes are 1ft long with a nozzle diameter of 3.5mm and 1/2\"-20 pipe thread.
**Note:** Though we do use these pipes in our SparkFun Third Hand, it does **NOT** include [any gripper hand hardware](https://www.sparkfun.com/products/12033) or base block used in the kit. These parts will need to be purchased and assembled separately.
