Hydraulic Pressure Test Gauge

The Hydraulic Pressure Test Gauge is used to test pressures in most compact tractors and equipment. The 2.5″, 0-5000 psi liquid filled gauge is graduated in 100 psi increments for easy readings, and the 30″ hose allows you to place the gauge in a convenient location while testing.

Available with or without couplers (Male is standard, Female upon request), this gauge is assembled and ready to use, no more shopping at various sources and paying extra shipping to piece a kit together yourself. KBOH can also make a custom gauge setup with two couplers on it so you can have one tool for different machines.

  • If you have the Single Point Hydraulic Coupler (SPHC) option (factory installed or added later) on your JD 1025R or 2025R, choose the 1/4″ ISO 16028 FF Female option
