1、WIDELY USED: This excavator hydraulic pressure gauge is suitable for various excavator pumps, compressors, hydraulic presses, pneumatic equipment, and motors. Widely used in construction, shipping, etc. 2、ACCURATE PRESSURE GAUGE: The hydraulic gauge kit has three different ranges of pressure gauges, 0 to 3500PSI 25MPa, 0 to 5800PSI 40MPa, and 0 to 8600PSI 60MPa. By using two units and accurate scales, the instrument is accurate in measuring pressure. 3、INTERCHANGEABLE TEST COUPLINGS: The excavator hydraulic test suite includes 8 interchangeable test couplings, with sizes of G1/8, G1/4, G3/8, M10/1, M10/1.25, M14/1.5, UNF7/16 20 and UNF9/16-18, as well as a quick connector (for Caterpillar CAT). 4、DURABLE MATERIAL: The hydraulic gauge test suite includes a corrosion resistant pressure gauge and a strong strength carbon steel coupling. The working oil filled in the instrument effectively avoids vibration and pulsation. 5、PORTABLE HOUSING AND 5.25IN TEST HOSE: All components of the hydraulic test gauge are neatly stored and tightly placed in a thickened plastic toolbox. The compact design saves storage space and is easy to carry. In addition, three test hoses help extend the pressure test gauge inside the machine for easy reading.
