Inline Hydraulic Pressure Gauge 0–5000 PSI – JIC 6 & JIC 8 (3/8" & 1/2") for Dump Trailer & Hydraulic Systems

Inline Hydraulic Pressure Gauge (0–5000 PSI) Monitor Real Working Pressure in Your Dump Trailer Hydraulic System The Primary Mover Inline Hydraulic Pressure Gauge is a simple but powerful tool designed to give you real-time visibility into your hydraulic system performance. Built for dump trailers, truck beds, and hydraulic power units, this liquid-filled 0–5000 PSI gauge installs directly inline using JIC male to female connections, allowing you to monitor pressure exactly where it matters most. Available in: • #6 JIC (3/8") • #8 JIC (1/2") Why This Matters for Dump Trailer Performance Most hydraulic issues come down to one thing — pressure. Without a gauge, you're guessing. With this installed, you know exactly what your system is doing. Our 12V hydraulic power units are typically set to operate up to 3200 PSI. Once you reach that point, the pump can no longer push additional load. This gauge allows you to: See how close you are to max system capacity Determine safe working load for your dump trailer Identify performance limitations before they become problems Quickly diagnose hydraulic issues without guessing Real-World Example Let’s say your dump trailer successfully lifted 3 yards of material. With this gauge installed: If you see ~3000 PSI, you’re already near max capacity If you see ~1000–1500 PSI, you still have headroom to increase load This removes the guesswork and helps you better understand how your hydraulic system is performing under load. Important: This example is for educational purposes only and assumes your system is designed to operate up to approximately 3000 PSI. Never exceed your truck or trailer’s rated capacity or recommended load limits. Hydraulic pressure is only one part of the system — structural limits, axle ratings, and safety considerations must always come first. Every hydraulic system is different. Some systems may be designed to operate at lower pressures (such as 2000 PSI), so always understand the specifications of your specific setup before using pressure readings to make decisions. Installation & Best Use This is an inline pressure gauge, meaning it installs directly into your hydraulic circuit. Commonly installed on the A port (high-pressure side) Can be mounted directly at the pump outlet Connect your hose to the opposite side going to the cylinder Works with any system using JIC fittings Ideal for both permanent installation or temporary troubleshooting setups. Key Features 0–5000 PSI Range – Covers full operating range of dump trailer hydraulics Liquid-Filled Gauge – Reduces vibration and improves accuracy Inline Design – No tees or extra fittings required JIC Male x Female Connections – Simple installation Available in #6 and #8 Sizes – Fits common hydraulic setups Heavy-Duty Construction – Built for real jobsite conditions Recommended Applications Dump trailer hydraulic systems Truck dump bed conversions Scissor hoist systems 12V and 24V hydraulic power units Hydraulic troubleshooting and diagnostics Product Videos & System Setup Help Want to better understand pressure, troubleshooting, and hydraulic system performance?

It’s not required, but it’s one of the best tools you can have. It allows you to monitor system performance, avoid overloading, and quickly diagnose issues. Where should I install the pressure gauge? The most common location is on the A port (pressure side) of your pump. This gives you the most accurate reading of working pressure going to your cylinder. What PSI should my system run at? Most dump trailer hydraulic systems operate between 1000–3000 PSI depending on load. Our power units are typically set around 3200 PSI relief. Can this help diagnose hydraulic problems? Yes. This is one of the most effective diagnostic tools available. It can help identify weak pumps, overloaded systems, pressure loss, and other common hydraulic issues. Will this work with my existing hydraulic setup? If your system uses #6 (3/8") or #8 (1/2") JIC fittings, this gauge will install directly inline with no additional adapters.
