Hydraulic Nitrogen Accumulator Charging Kit, Nitrogen Fill Kit, Nitrogen Pressure Test System with 7 Couplings, 3 Gauges, and 1 Gas Hose

Worked perfectly for filling my accumulator bottles with nitrogen with no issues.

Comes with everything you need. Has every adapter connector for whichever make and model excavator you have. Also includes 3 different pressure gauges depending on what you are checking. Guages are smooth and not jerky and connectors glide on easily. Great buy.

Have not used tooling yet. Upon opening package, found that plastic case was smashed and latch was broken off. Also parts and pieces where scattered in shipping box. Shipping box did not appear to be damaged.

All the components are made well with heavy materials. Has several different sized adapters for refilling a variety of different accumulators. Only issue is the threading seems to be less than idea, I had trouble getting pieces to screw all the way together. Not a deal breaker but thought it was worth mentioning.

Everything has worked perfectly so far for my application. The unit feels solid in my hands and all parts are well made. I'm hoping to get many years of use out of this pump.

Foolishly I expected CGA-580 compatibility. I haven't determined what the G 5/8 adapter is, but it's not cga-580. Seems to be descent quality. I did find a cga-580 to 1/4 pipe for the regulator. Like another person mentioned, use a regulator to avoid blowing the diaphragm or bladder out. Nothing's ever easy....

I hope this work for at least a year

Great kit, works as advertised, nice carrying case also:)
