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 or base block used in the kit. These parts will need to be purchased and assembled separately.
