The Vevor hydraulic nitrogen accumulator charging kit is an all-in-one pressure test system designed for accumulator nitrogen charging and hydraulic pressure testing. It includes three gauges rated at 1500, 4000, and 6000 PSI along with six couplings, a gas hose, a valve, and a CGA580 adapter for broad equipment compatibility. Glycerin-filled gauges and SUS304 construction help provide stable readings and durable performance in demanding environments. The kit is suited for maintenance and diagnostics on excavators, loaders, bulldozers, farm machinery, and other hydraulic systems. A carry case keeps the components organized for transport and storage.
