Nitrogen pressure maintaining kit

The Nitrogen Pressure Retention Kit is a pipeline leak testing tool set that includes a pressure-reducing valve, pressure gauge, and connecting pipes. After nitrogen is filled, pressure changes are monitored to accurately detect leaks and ensure system safety. It is suitable for a variety of pipeline testing scenarios.
It is used for installation, acceptance, and maintenance inspection of air conditioners, refrigeration units, and gas pipelines.
The high-pressure copper valve body and precision pressure gauge are manufactured and pressure-tested to ensure accurate, safe, and durable testing.
Service includes selection and operation guidance. Advantages include accurate testing, wide compatibility, ease of operation, and high safety.
The Nitrogen Pressure Retention Kit is a specialized tool set for testing the leaks of piping systems. Its core advantages are "high-precision testing + safe compatibility in all scenarios." The complete set includes a high-pressure brass pressure reducing valve, a precision pressure gauge, leak-proof connecting hoses, and various sizes of quick connectors. By filling the pipeline with dry nitrogen and monitoring pressure changes in real time, it can accurately detect pressure drops as small as 0.01 MPa/h, quickly locating leaks and preventing system failures or safety hazards caused by media leakage. Core selling points directly address testing needs: the pressure-reducing valve features a pressure adjustment knob and overpressure protection valve to prevent overpressure from damaging pipelines; the pressure gauge dial features a luminous coating for clear readings in dim conditions; the connecting hoses include anti-drop clips on both ends; and some kits include a pressure recording function to store test data for easy traceability. Applications include refrigerant pipeline acceptance after installation of air conditioners/heat pump units, leak testing during industrial refrigeration system maintenance, safety pressure testing of gas pipelines (natural gas and liquefied gas) after installation, and pressure testing of water supply and drainage pipes. Whether performing on-site operations at professional auto repair shops or refrigeration maintenance companies, or compliance testing during project acceptance, this system efficiently checks leaks and ensures safe and efficient operation of piping systems.
