G1/2" external thread brass nickel-plated high pressure screw connectors can withstand pressures up to hundreds of bar and are suitable for various high-pressure fluid transmission systems. Under high-pressure environments, the fittings can maintain a stable working state without leakage or damage. Nickel plating gives the fittings corrosion resistance and allows long-term stable use in humid, acidic and alkaline environments or environments containing organic solvents, reducing maintenance costs and replacement frequency. Precision-machined external threads and sealing surface design ensure that the fittings are leak-free during operation, greatly improving the safety and reliability of the system. The nickel-plated surface has a higher hardness, which effectively reduces the wear of the fitting surface under the impact of high-pressure fluids and extends the service life of the product. It also has strong adaptability and can meet the needs of various high-pressure fluid systems, especially suitable for high-demand environments in hydraulic, pneumatic, chemical and other fields.
