Liquid Cooling Quick Disconnect Coupling

GQD

Product Introduction

This product is manufactured by ZJK Industrial Co. (NASDAQ: ZJK), a supplier of connectors for NVIDIA. Guqi, as the Taiwan distributor, is committed to providing professional solutions.


 

Quick Disconnect Couplings 

(also known as Universal Quick Disconnect, UQD) are key components in liquid cooling systems, primarily used in high-performance computing devices like AI servers and supercomputers. These couplings feature fast connect and disconnect capabilities, along with leak-free operation, hot swapping, and secure connections. They comply with OCP (Open Compute Project) standards, enabling quick and reliable liquid connections while meeting the interchangeability requirements of small hose liquid cooling racks.

Sealing Ring Performance



This product is suitable for a variety of working environments. Based on your needs, you can select a sealing ring that matches the liquid medium, operating temperature, and pressure conditions. Please refer to the following selection guide to choose the appropriate sealing ring for your application:

No. Name Min and Max Allowable Temperature Application
1 EPDM (Ethylene Propylene Diene Monomer) -50℃-150℃ Seals in high-temperature steam environments and bathroom equipment. Apply to rubber parts in braking systems and seals in radiators (automobile water tanks).
2 FKM (Fluoroelastomer) -20℃-250℃ Used for seals in automobiles, motorcycles, diesel engines, fuel systems, and chemical plants.
3 FVMQ (Fluorosilicone Rubber) -20℃-250℃ Exceptional resistance to oils, solvents, and fuel oils, in addition to outstanding performance under extremely high and low temperatures.
4 FFKM (Perfluoroelastomer) -50℃-200℃ The perfluorinated series products are widely used in the semiconductor industry and information-related industries, including PVC, CVD, etching processes in the film process, and various high vacuum sealing processes.
5 NBR (Nitrile Butadiene Rubber) -40℃-100℃ Used for making fuel tanks, lubricating oil tanks, and rubber parts used in petroleum hydraulic oil, gasoline, water, silicone grease, silicone oil, diester lubricating oil, ethylene glycol hydraulic oil, and other fluid media, especially for sealing parts. It can be said to be the most widely used and lowest-cost rubber seal.
6 HNBR (Hydrogenated Nitrile Butadiene Rubber) -40℃-150℃ Application in laundry or dishwashing detergents. In the air-conditioning and refrigeration sector, it is extensively utilized in seals within the environmentally friendly refrigerant R134a system as well as in seals of automotive engine systems.
