When your tractor or equipment starts acting up, a vacuum gauge can be your best diagnostic buddy. Whether you’re troubleshooting engine problems, checking hydraulic system suction, or monitoring vacuum-operated accessories, this 2.5-inch vacuum gauge gives you clear, accurate readings from 0 to 30 inches of mercury. It’s the kind of tool that helps you spot problems before they turn into expensive breakdowns.

- Measures vacuum from 0 to 30 inches Hg, covering the full range for most applications

Built for Real Farm Work
This vacuum gauge is perfect for troubleshooting diesel engines on tractors, combines, and other farm equipment. You’ll find it handy for checking turbo wastegate operation, diagnosing EGR system problems, or monitoring vacuum pumps that operate hydraulic systems. It’s also useful for testing vacuum-operated accessories like PTO clutches and brake boosters on older equipment.
Made to Last
Farm equipment gauges take a beating from constant vibration, temperature swings, and dusty conditions. This gauge is built to handle all of that while keeping its accuracy. The sealed mechanism protects against moisture and dirt, so you get reliable readings whether you’re in the shop or out in the field.
Installation Notes
The 1/4 inch NPT bottom connection screws right into most vacuum lines or manifolds. Use pipe thread compound on the threads for a leak-free seal—vacuum leaks will throw off your readings. Mount it where you can see it clearly, and remember that vacuum lines need to be routed away from hot exhaust components.
