The chiller comes with a 3/8" Inside Diameter Barb. 

Our spindle accepts a 6mm inside diameter and 10mm outside diameter hose.

Since the Outside diameter of what the spindle accepts is greater than the inside diameter of the hose barb we need to utilize an adapter. 

All current chiller orders will come with (2) stretches of 3/8" hose, and (2) 1/4" to 3/8" barbs. You can add hose clamps found at your local hardware store or use any zip-ties you have available.

Contact us at [email protected] if you'd like to take advantage of the free adapter to be utilized with our chiller or your Spindle Cooling System.  

To install the adapters on the chiller, take the small stretch of hose provided and put it on the hose larger end of the hose barb, and the chiller's barbs. 

Then take the hose supplied with your spindle cooling system, and slide it onto the smaller side of the barb. 

If you'd like to use hose clamps, you will need to slide them onto the hose before making that connection. While the hose clamp is not necessary to work, it does delivery peace of mind.
