About Pressure Gauges

About Vacuum Pumps

Convenient for one-handed liquid sampling and extraction, these pumps are often used for vacuum filtration and bleeding hydraulic and liquid lines. They can also be used for pressure applications up to 30 psi.

Tire Pressure Gauges with Indicator Bar

A bar slides out of the top of these gauges to display pressure reading.

Black plastic-coated brass gauges are non-slip for an improved grip. The matte black finish won’t reflect light. Stainless steel gauges are more corrosion resistant than steel and brass gauges.

Gauges with a quick-disconnect tip press into the valve stem rather than clamping over it for a faster setup and more accurate readings.

Gauges with a 10° bend are best for reaching valves on large tires.

Calibrators for Tire Pressure and Inflator Gauges

Test the accuracy of tire pressure gauges and tire inflation gauges. Designed to higher accuracy standards than typical tire gauges, these calibrators are not meant to be used to regularly check tire pressure directly. Instead, they serve as an objective reference to eliminate inaccuracies and discrepancies between your gauges. To use, check tire pressure first using the calibrator and then again with your tire pressure gauge. Make calibration adjustments to your gauge until its reading matches the reading on the calibrator.

Compression Testers

Check engine compression to maintain top performance.

Testers with a quick-release coupler make it easy to connect and disconnect the gauge and the hose.

Testers that include both injector adapters and glow plug adapters are compatible with most diesel engines.

Add an optional adapter if you tester does not come with an adapter that matches your engine's spark plug thread size.

Fuel Injection Pressure Testers

Schrader Valve

Check fuel injection pressure to maintain your car's gas mileage. Attach these testers to your fuel line and idle the engine to test—stable pressure readings indicate that all is well. Fluctuations in pressure can result from a number of issues, including a failing fuel pump, clogged fuel filter, faulty fuel pressure regulator, or leaking fuel injectors.

Cylinder Leak Testers

Test how well your engine cylinder holds compressed air. Often used after getting a low reading from a compression tester, these leak testers show the percentage of the air leaking out of your cylinder. Remove all spark plugs from your engine and rotate it so the cylinder being tested is at the top. Make sure the cylinder is top dead center on its stroke, with both valves closed. Connect one end of these testers to the spark plug hole, and the other to a compressed air source. Fill the cylinder to its specified air pressure, and the gauge on these testers will show how much air is leaking out.

Add a whistle to help pinpoint the location of a leak. If the sound of the whistle changes while the cylinder moves through its stroke, you’ve found the leak. Connect to the end of the hose or adapter on a leak tester.

Check the vacuum levels in high-vacuum pumps, valves, and chambers with this compact gauge. Use a ring and clamp (both sold separately) to connect them to another quick-clamp high-vacuum fitting, also known as KF, QF, and NW fittings. The digital display shows measurements in torr, mbar (millibar) and hPa (hectopascal).
