*Accurate Pressure Gauge: The hydraulic gauge kit has three pressure gauges of different ranges:0-3500PSI/25MPa, 0-5800PSI/40MPa, 0-8600PSI/60MPa. With two units and precise graduations, the meters are accurate in measuring pressure. *Interchangeable Test Couplings: Eight interchangeable test couplings are included in this excavator hydraulic pressure test kit, with the sizes of G1/8, G1/4, G3/8, M10/1, M10/1.25, M14/1.5, UNF7/16-20, and UNF9/16-18, which are suitable for many kinds of standard excavators. *Durable Materials: This hydraulic gauge test kit contains corrosion resistance gauges and carbon steel couplings with high strength. The working oil filled in the meters effectively avoids vibration and pulsation. *Portable Case & 5.25' Test Hose: All parts of the hydraulic pressure test gauge are neatly stored and tightly placed in a thickened plastic toolbox. The compact design makes it save storage space and easy to carry. In addition, three test hoses help extend the pressure test gauge to the inside of the machine for easy reading. *Wide Application: This excavator hydraulic pressure gauge comfortably fits for pumps, compressors, hydraulic presses, pneumatic equipment, and motors of various excavators. It is widely applied in construction, shipping, etc. Specifications Pressure Gauge 1: 60 mm-3500PSI/25MPa Pressure Gauge 2: 60 mm-5800PSI/40MPa Pressure Gauge 3: 60 mm-8600PSI/60MPa Test hose: Length=1.6 M / 63"QTY: 3PC Test coupling: G1/8QTY: 1PC Test coupling: G1/4QTY: 1PC Test coupling: G3/8QTY: 1PC Test coupling: M10/1QTY: 1PC Test coupling: M10/1.25QTY: 1PC Test coupling: M14/1.5QTY: 1PC Test coupling: UNF7/16-20QTY: 1PC Test coupling: UNF9/16-18QTY: 1PC Quick connector -(for Caterpillar CAT)QTY: 1PC Package Content 1 Set Excavator Hydraulic Pressure Test Kit
