Application: Hydraulic Products
4221
75 GPM hydraulic circuit tester. Comes with two pressure gauges and three 9-volt batteries. Wt., 21 lbs., 3 oz.
  • 50 and 75 GPM hydraulic oil flow testers accurately measure oil flow, temperature, and pressures against manufacturers’ specifications.
  • Troubleshoot hydraulic circuits and isolate faulty components on mobile equipment, machine tools, fork lifts, agricultural and industrial tractors, and equipment (open or closed) hydraulic systems with capabilities up to 75 GPM at pressures to 5,000 PSI. Models include features such as an automatic pressure compensating load valve that lets you increase flow without affecting the pressure settings. Temperature flow and RPM readings are displayed in metric or English, and accurate to within plus or minus 2% of full scale. Each tester is protected by a safety disc, which ruptures automatically if pressures exceed the upper limits.
