Sinocmp Hydraulic Pressure Gauges Kit Test, 9 Couplings, 59 Inch 3 Test Hoses, 3 ?All-in-One Convenience design?3x Test Hoses, 11x Test Couplings, 3x Hydraulic Test Guages, 1x Aluminum Portable Storage Case. All the parts of the kit are placed in the box with a compact packaging design saves storage space and is easy to carry. ?Stable Pressure Measurement?Hydraulic gauge kit has 3 gauges with a diameter of 63 mm with different ranges of measurement:0-250 Bar/0-4000 PSI, 0-400 Bar/0-6000 PSI, 0-600 Bar/0-10000PSI. The display has scale parameters in two units can accurately measure pressure. The instrument filled working oil to effectively avoid vibration and pulsation, providing stability for long-term use and measurement. ?Interchangeable Test Couplings Tee Connectors?The hydraulic instrument kit contains high-strength carbon steel couplings: G1/8, G1/4, G3/8, M10*1, M10*1.25, M14*1.5, UNF7/16-20, UNF9/16-18, NPT1/4, M8*1.0, Quick connector B compatible for CASE/John Deere ?Test Hose?The 60 inches long test hose is not easy to age and bends easily, also can extend the pressure test gauge into the interior of the machine to measure data more easily. ?Industrial Applications?This is a practical kit can be widely used in pumps, compressors, hydraulic presses, and motors of various excavators. Another using in pneumatic tools, air compression systems, agricultural machinery, industrial equipment, medical equipment, gas treatment equipment, water treatment equipment and more.
