Hydac FPK 250 F2.5 G4 K Accumulator Charging Kit includes hose w/ G1 bushing + G4 adapter (Discontinued)

Hydac Accumulator Charging Kit Type FPK for use with Gas Valve Version 1 M28 x 1.5 for SBO and SK. To maintain system performance HYDAC recommends that the gas precharge pressure is checked regularly. The inevitable loss of gas precharge pressure due to permeability will change the system effectiveness performance and could cause damage to the bladder, diaphragm, or piston accumulator.HYDAC charging and gauging units allow hydro-pneumatic accumulators to be precharged with dry nitrogen. For these purposes, a charging and gauging unit is connected to a commercially available nitrogen bottle via a flexible charging hose.These units also allow maintenance personnel to check the current gas precharge pressure of an accumulator. For critical systems, consider the use of a permanent gauging block which will provide for continuous monitoring.
