The hydraulic accumulator charging kit is mainly composed of storage case, valve body (with M28×1.5 internal thread), central spindle, non-return valve, pressure relief valve, pressure gauge, charging hose (typically 3 meters long), connection adapter, spanner wrench, gas valve torque wrench, pull rod and extension segments, etc.
This product is used to charge nitrogen for bladder type, piston type and diaphragm type accumulators, and it can also work as pressure tester and adjustor, too. For our charging kit, the pressure gauge is imported from Germany, the charging hose is flexible high pressure type with small diameter, and the connection adapters are supplied in a complete series to realize universal use. So, it is highly recommended.
