You pull an old hydraulic hose off a piece of equipment, wipe away the dirt, and notice a string of numbers and letters printed along the outside. You see something like “SAE 100R2AT” followed by pressure ratings, hose size, and other manufacturer information that you may or may not understand.

You’re replacing a hydraulic power unit on a dump trailer, service truck, or snowplow, and one of the first questions that comes up is whether you need a 12-volt or a 24-volt system. Choosing the wrong voltage can create installation problems, damage electrical components, or prevent the unit from operating

A lot of pneumatic problems get blamed on the cylinder, valve, or air tool when the real issue is the air going into it. If you’ve ever dealt with inconsistent pressure, moisture in the air lines, or components that seem to wear out faster than they should, it’s worth taking

Replacing a hydraulic cylinder sounds simple until you start looking at the old one. You know it needs to lift, push, or hold a load just like the original, but now you’re staring at terms like bore, stroke, rod diameter, and mounting style. If even one of those measurements is

It usually happens at the worst possible time. A hydraulic hose bursts in the middle of a job, oil is everywhere, and now the equipment is down until you can get a replacement. The next question is almost always the same: “How do I measure this thing?” The good news

A hydraulic system usually gives you some warning before it quits altogether. Cylinders start moving more slowly than usual, or a pump starts getting louder every week. It’s tempting to keep working and deal with it later, but small hydraulic problems have a habit of becoming expensive ones. The good

Grab the wrong fitting off the shelf, and you’ll know it fast. Threads that won’t quite seat, a hose that weeps under pressure, or a connection that fails the moment you cycle the system. The frustrating part is that JIC, ORFS, NPT, and BSPP fittings can look nearly identical at

Not every hydraulic system has a building to plug into. Dump trailers, snowplows, service trucks, and lift gates all need hydraulic power on the move, often nowhere near an outlet. That’s the gap a DC hydraulic power unit fills. It’s a compact, self-contained system that runs on a 12-volt or
