Nut

1. Plumbing Pipeline System
Drinking water pipe connection: In the copper pipes and PPR pipes of homes or commercial buildings, the mesh nuts are matched with the joints. The mesh increases the friction when tightening by hand, which is convenient for the installer to operate by hand, and ensures the sealing of the pipe interface (such as the connection between the faucet and the water inlet pipe, the working pressure is ≤1.6MPa).
Floor heating/radiator pipe fixing: At the connection between the floor heating manifold and the branch pipe, and the joints of the radiator inlet and outlet, the mesh nuts can resist the slight vibration caused by the thermal expansion and contraction of the pipe, and prevent the interface from loosening and leaking.
2. Automobile Industry
Engine compartment pipe fixing: At the quick joints of the fuel pipe and coolant pipe of the car, the mesh nuts can enhance the bite with the wrench through the surface texture, avoid slipping during installation or maintenance, and withstand the high temperature (-40℃ to 125℃) and vibration environment of the engine compartment.
Automobile air conditioning system: At the junction of the aluminum tube and the copper tube of the air conditioning pipeline, the mesh nut is used in conjunction with the sealing ring to achieve sealing. The corrosion resistance of the brass material can prevent erosion by the refrigerant.

3. Home appliance manufacturing
Washing machine/dishwasher water circuit parts: The connection between the washing machine water inlet valve and the water inlet pipe, the fixing point of the dishwasher spray arm, the mesh nut is not only convenient for quick tightening during installation, but also can keep it tight during the vibration of the equipment operation to prevent water leakage.
Refrigerator refrigeration system: The pipe joints between the refrigerator evaporator and condenser, the mesh nut is combined with the bell-mouth sealing structure to ensure that the refrigerant does not leak. At the same time, the low-temperature performance of brass is stable and will not become brittle due to temperature changes.
