Nitrogen hydraulic accumulator fill/charging tool with a high pressure 3000PSI gauge. This tool has a 0-5000PSI high pressure supply-side (nitrogen tank gauge), and 0-3000 PSI (delivery-side gauge). Both gauges are glycerin filled. The nitrogen tool has a 6000PSI rated stainless steel shut-off valve and a 5000 PSI rated bleed-off valve, for releasing excess pressure or releasing line pressure after charging is complete. Both valves have knurled knobs. Comes with a 8' stainless steel braided hose and stainless steel no-loss chuck, which are both rated for 3000 PSI. This tool is designed to charge hydraulic accumulators, aircraft struts, or any nitrogen chamber on any other hydraulic system needing high pressure charging, and utilizes a schrader style chuck.The no-loss schrader style chuck is 100% stainless steel and is mounted to a swivel fitting that rotates 360 degrees. This allows precise and repeatable setting of nitrogen/air pressure for all nitrogen tanks, accumulators, chambers with a schrader valve stem. The valve opens and closes under constant pressure using the small "T" handle. Tank supply nipple comes standard with CGA-580 brass nipple.
