Keeping your excavator running smoothly means knowing exactly what's happening under the hood. This hydraulic pressure gauge set is designed specifically for heavy equipment technicians and maintenance teams who need accurate, reliable readings to diagnose hydraulic problems before they turn into expensive downtime.
With four precision silicone oil gauges covering 1500psi, 3500psi, 6000psi, and 10000psi ranges, you have the flexibility to test low-pressure systems and high-pressure hydraulic circuits all with one compact kit. The silicone oil filling ensures smooth, accurate needle movement even in harsh vibration environments common on construction sites.
The 10 included couplings cover the most common hydraulic fittings you'll encounter: G1/8, G1/4, G3/8, M10*1, M10*1.25, M12*1.5, M14*1.5, UNF7/16-20, UNF9/16-18, and Quick connector B. Whether you're working on Sany, Caterpillar, CASE, John Deere, Komatsu, HITACHI, Kawasaki, or Kato excavators, you'll have the right adapter to connect quickly and start testing.
These aren't delicate instruments—they're made for real-world conditions. The stainless steel gauges are waterproof and resistant to the dirt, dust, and moisture you'll find in equipment maintenance bays. The thickened carrying case features molded foam compartments that keep each gauge and coupling securely in place, preventing damage during transport and storage.
Use this kit to check hydraulic pressure in cylinders, test pump output, verify relief valve settings, and diagnose pressure drops in hydraulic lines. The clear, easy-to-read gauges give you instant feedback on system performance, helping you make informed decisions about repairs and maintenance before minor issues become major failures.
