❄️ Kool Connectors – Motor Side Only

Premium Quick-Disconnect Fittings for Water-Cooled Spindles

Designed in collaboration with Koolance, these exclusive quick-disconnect fittings replace the standard barbed connectors on your spindle motor—delivering a clean, reliable, and no-spill solution for water-cooled setups.

⚠️ Important Note:
These connectors are for the motor side only and are not compatible with chillers.
Do not overtighten – made from precision brass, these fittings require only hand-tightening. Over-tightening may cause them to split. Damaged connectors due to overtightening will not be replaced.

✅ What’s Included

(2) PwnCNC Exclusive M8x1.0 Male Fittings
Designed to replace the spindle’s original barbed outlets
(2) 10mm OD / 6mm ID Female Kool Connectors
For seamless connection with your coolant tubing

🔧 Installation Tips

We recommend hand-tightening only for a secure and damage-free fit.
Compatible with our clear 10/6mm tubing (available by the foot).
Using blue/orange PU tubing? Gently heat the tube tip to ease the fit onto the female connector.
Full install instructions available here: Kool Connector Installation Guide

💡 Pre-Installed with ATC Systems

If you ordered these with your Spindle System or ATC System, we’ve already installed them for you. Just plug in your tubing and get carving.

Frequently Asked Questions

I thought I wouldn’t buy them because of the cost but decided to get them. Glad I did. Best thing ever. No leaks and they just snap on & off.

This spindal is the best piece of equipment that I have added to my shop. It was a great addition to my Longmill and service from Pwn was great when I received my spindal kit the controller was damaged.
Sent one email and got a reply the next morning and a replacement was on the way. Can't wait to see the new Dominator 4x8

PWN and Customer Support

Installed my new spindle on Christmas Day. Had a couple of issues so submitted a ticket. A couple hours later, on Christmas Evening, Clinton was back with an answer for me. Major kudos to Clinton!!!!!
