Description
Hydac Accumulator Charging & Testing Kit 3500 psi 250 bar w/ Gauge Hoses
This Hydac hydraulic accumulator charging and testing kit is a complete, self-contained portable unit for checking and adjusting the nitrogen pre-charge pressure in hydraulic accumulators. The kit includes a test valve and pressure gauge assembly, two hydraulic hoses with brass fittings, a set of adapter fittings, and a red molded carry case with custom foam insert. The gauge reads dual-scale: 0–3500 psi and 0–250 bar, matching the kit's rated maximum pressure. Hydac labels this product the "Füll- und Prüfvorrichtung für Hydrospeicher" (Charging and Testing Unit for Accumulators), as seen on the case lid.

Applications
Hydac accumulator charging and testing kits are standard service tools used with bladder, piston, and diaphragm-type hydraulic accumulators in industrial hydraulic systems. Hydraulic accumulators store pressurized fluid energy by compressing a nitrogen gas charge; over time the pre-charge pressure drops and must be checked and restored to maintain system performance. This kit connects between a nitrogen bottle and the accumulator's gas valve, allowing a technician to read the current pre-charge pressure and add or release nitrogen as needed. These kits are used across industries including mobile hydraulics, industrial machinery, injection molding, presses, and any hydraulic circuit incorporating accumulators for energy storage, pulsation damping, or emergency actuation. Hydac is a well-established German manufacturer of hydraulic components, with accumulator service tools of this type being a staple of preventive maintenance programs on hydraulic equipment worldwide.
This Hydac Accumulator Charging and Testing Kit (3500 psi / 250 bar) has been inspected and appears to be in good used condition. The kit includes the test valve and gauge assembly, two hydraulic hoses, a set of brass adapter fittings, and the original red carry case with foam insert. Components show light surface wear and some patina on the brass fittings consistent with prior use, but no visible damage to the gauge face, hose connections, or case. The carry case is intact and closes securely. Please view our photo set and contact us if you have any questions.
