This hydraulic pressure test kit is designed for single-point testing and charging of low-pressure accumulators in one compact set. It includes a nitrogen charging valve, mechanical pressure gauge, adapter fitting, gas hose, and CGA580 adapter for maintenance and pressure inspections. The glycerin-filled gauge and SUS304 construction help provide stable readings and durable performance in demanding environments. It is suitable for use with heavy equipment such as excavators, loaders, bulldozers, and farm machinery. A carrying case keeps the components organized for transport and storage.
