The Nitrogen Charging and Pressure Adjustment Tool is a compact and portable maintenance device used for filling, adjusting, and measuring nitrogen gas in bladder, piston, and diaphragm-type hydraulic accumulators. It provides safe gas transfer by connecting the nitrogen cylinder to the accumulator and enables controlled charging and discharging through its integrated pressure gauge, valve assembly, and connection adapters.

With its durable body structure, leak-proof connections, and adapter options compatible with different accumulator types, it is an ideal solution for both field use and workshop maintenance. It enables safe and efficient operations such as gas pressure control, post-charging pressure adjustment, and accumulator pre-charging during system maintenance.
