❄️ 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) 10mm OD / 6mm ID Female Kool Connectors

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.
