Steel Dragon Tools 50557 Model 1450 Hydrostatic Pressure Test Pump - 860 PSI with 3/4" Connector for Plumbing, HVAC, and Industrial Applications

This is a well built tool for the price and worked well for my jobs. The pump has a good solid feel. I hydro tested 3 compressed air tanks to 260 psi, the pump easily achieved this pressure and the relief valve held fine for the 15 minute duration of each test with no leakage observed. The hose connection is 1/2. The built in water tank is a nice convenience, just fill it and go to work. There is a small filter on the intake but you should use clear water just the same.A few things to note:1) The water tank came with a "factory dent", shallow and about 1" long, it was perfectly painted and there was no damage to the sealed inner box the unit came in so i surmise the dent was on the unit when it was painted and went in the box, it in no way hampered the operation so i wasn't concerned.2) The gauge was not at zero, this often happens when inexpensive gauges are handled roughly. I simply popped the lens off and then removed the pointer by levering it straight off with two putty knives. I hooked a quality gauge to the hose with a few fittings and pumped it up to 100 psi and reinstalled the pointer at the 100 psi mark. The gauge then zeroed correctly and tracked with my good gauge perfectly to the 260 psi test pressure. 5 minute fix.3) The foam on the handle isn't much, again i wasn't concerned.All in all a very nicely built and useful tool for the price. Perhaps if you are using this type of unit daily or at the top of it's pressure rating you might require something more expensive. My expected use is perhaps 6 times per year so i could not justify spending twice as much. This unit feels very solid, i don't see it wearing out any time soon. Good Luck!
