Versatile Applications: The hydraulic test kit works for frequent inspections of excavators (Caterpillar, Komatsu, and other brands), loaders, and bulldozers. Ideal for system maintenance, farm machinery, pressure calibration, and multi-valve diagnostics Easy Storage & Portability: With this hydraulic test gauge kit, all tools fit into one case, keeping them secure, organized, and protected from loss or damage Wide Compatibility: This hydraulic pressure gauge kit covers G, M, UNF, and NPT thread types and includes Type B and Type C quick connectors for multiple hydraulic systems. The flexible hose easily extends into narrow or hard-to-reach testing points Reliable Accuracy: Our hydraulic gauge kit features glycerin-filled gauges that resist leakage, avoid yellowing, reduce internal friction, and dampen vibration. 304 stainless steel housing ensures strength, heat, and corrosion resistance Complete Hydraulic Pressure Test Kit: This kit covers five pressure ranges (10/60/160/400/600 Bar). It includes five gauges, twenty couplings, four quick couplers, and three hoses. It is designed for low, medium, and high-pressure hydraulic systems
