1. “Plug-n-Cool“ self-closing companion valves.
When using the self-closing companion valves, defective components can easily be replaced during ongoing operations. This provides great added value for users, as there is minimal interruption to operations.
2.No refrigerant needs to be extracted and refilled going to great expense.
3.Extracting always entails polluting the environment.

From refrigerators to heat pumps, Ningbo Hcool Fititngs pre-install bidirectional self sealing quick couplings for your entire machine.
End users can replace and use it immediately, without the need to recycle refrigeratnt or vacuum-reducing your products's after-sales maintenance time by 80%.
"You make the equipment, we provide 'fast interfaces". From thread specifications to sealing materials, we offer comprehensive customization, allowing your refrigeration equipment to have a plug and play maintenance experience - one customization, lifetime load reduction.
Please contact me and let me know your requirements so that we can customize a quick connector specifically for you.
As someone who has been researching and producing in the refrigeration industry for many years. Ningbo Hcool fittings' team are well aware of OEM customers's anxiety about delivery time and understand the "zero tolerance" of refrigeration systems for leaks.
Therefore, relying on the fast response mechanism of our own factory, we can complete the verification from 3D drawings to prototypes in a very short time; At the same time, every quick connector undergoes 100% sealing and pressure resistance testing before leaving the factory, ensuring that you not only receive speed, but also stability and reliability for ten years.

for LCL, carton+ pallet to protect
for FCL, export carton or color box,pallet also is avaible based on needed.


Q1: What refrigerants is this quick connector suitable for?
A: Our product is compatible with the vast majority of refrigerants on the market, including R600a, R134a, R404A, R410A, R32, etc. The sealing material can be customized according to specific media (such as EPDM, FKM, HNBR) to ensure long-term compatibility without corrosion.
Q2: Is there really no leakage when disconnected?
A:Yes. We adopt a bidirectional self sealing valve core design, with independent shut-off valves integrated inside both male and female heads. When the thread is unscrewed, the valve core resets simultaneously under the action of the spring.
Q3: How much pressure can it withstand? What is the working temperature range?
A:The standard model has a pressure resistance of 35 bar, but we have also customized systems for high-pressure operation, such as the R744 system. The standard operating temperature range is -40 ℃~+125 ℃, which meets the full working condition requirements of refrigeration equipment from freezing to heat dissipation.
Q4: We are an AC factory, can you customize according to our interface specifications?
A:Yes. We provide fully customized services: you only need to provide interface drawings or working condition requirements (pipe diameter, thread type, installation size, medium type, etc.), and we will complete the entire process from 3D drawing to sample verification and mass production in one stop.
