The Nordstrom 400-D High-Pressure Hand Gun is rated at 10,000-11,000 psi (690-759 bar) and includes many features for meeting the exact demands of replacing sealant in lubricated valves. One of the most outstanding features of the 400-D Hand Gun is the large fluid capacity, which permits long periods of operation between recharging.
By using a special-formula hydraulic fluid in the pumping mechanism, the gun pumps smoothly and with minimum effort. Its powerful hydraulic floating piston principle forces sealant out of the fun with ease, regardless of the sealant viscosity.
