Accuracy at Every Pressure Point This hydraulic pressure test kit includes3 gauges, 3 test hoses, and 11 test couplings, all neatly organizedthe case. Wide measurement options: 0-3500 PSI/250 Bar, 0-5800PSI/400 Bar, and 0-8600 PSI/600 Bar. The gauges provide accuratereadings in both psi and bar units for versatile use. Our hydraulic pressure gauges areconstructed from 304 stainless steel, ensuring durability andresistance to impact. The built-in glycerin to keep the dial clearand transparent, preventing yellowing over time. The seal designprevents oil leakage, ensuring reliable performance. This hydraulic pressure test kit boasts11 diverse test couplings to meet the pressure measurement needs ofmost excavators and hydraulic systems. We've also enhanced theprotection of these joints by adding threaded protective caps,preventing deformation and damage due to accidental bumps. The 5.2ft / 1.6m long hoses provideflexibility and are can withstand high heat and pressure. Thehydraulic gauge kit comes complete with a robust aluminum alloycarrying case featuring a convenient card slot design and compactsize for organized storage and easy portability. Our excavator pressure gauge kit iscompatible with most excavators and machinery in variousindustries, making it an essential tool for professional pressuremeasurement personnel working in construction, machinery,shipbuilding, mining, petroleum, chemical, and more.
