About Pressure Gauges

Find a gauge with the right connection material and dial type—many with traceable calibration certificates.

Pressure Gauges

These are the most commonly used pressure gauges. Use them with pumps, filters, regulators, and in process lines to measure and display pressure.

High-Clarity Vibration-Resistant Pressure Gauges

These gauges have a unique case design that eliminates the air bubble on the dial face, which can distort readings. The liquid in the dial reduces needle flutter for precise readings in high-vibration applications. Use them in pumps, filters, regulators, and in process lines to measure and display pressure. Mount gauges with the dial face upright.

High-Clarity Vibration- and Corrosion-Resistant Pressure Gauges

Gauges have a glycerin-filled dial that reduces needle flutter and a unique case design that eliminates the air bubble on the dial face that can distort readings. The case material is nylon and connection threads are stainless steel for excellent corrosion resistance. Use gauges with pumps, filters, regulators, and in process lines to measure and display pressure. Mount them with the dial face upright.

Fuel Injection Pressure Testers


	For Schrader Valves

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.
