Koolance
QDT2 EPDM Male Quick Disconnect No-Spill Coupling, Male Threaded G 1/4 BSPP
Best quick-disconnect fitting for mess-free custom liquid cooling maintenance.
This Koolance QDT2 EPDM Male Quick Disconnect Coupling is essential for building clean, custom PC liquid cooling loops. It utilizes patented quick disconnect technology featuring an automatic shutoff mechanism for spill-free maintenance. The fitting includes a G 1/4 BSPP male thread, designed to screw directly into components like water blocks. When separated from its corresponding female QDC, fluid is automatically obstructed, releasing only about 0.2ml of coolant. This component is exclusively compatible with Koolance QDT2 female quick disconnects, ensuring system integrity and ease of use.

Know before you buy
No, this component is exclusively compatible with Koolance QDT2 female quick disconnects. Using it with other brands or series may result in leaks or a failure to seal properly.
The automatic shutoff mechanism is designed to minimize spillage, typically releasing only about 0.2ml of coolant during disconnection.
This coupling uses EPDM seals, which are specifically compatible with water and glycol-based cooling liquids. It is not recommended for use with fluids that are incompatible with EPDM rubber.
It is rated for a maximum pressure of 170.7 psi (12kgf/cm2) at 25°C and can withstand temperatures up to 80°C (176°F).
No, it features a standard G 1/4 BSPP male thread, allowing it to screw directly into most standard water blocks and cooling components without additional adapters.
