About Pressure Gauges

Manually pump air, water, or hydraulic fluid through your system so you can test fluid pressure in valves, hose, sprinkler lines, pipes, boilers, condensers, heat exchangers, pressure vessels, and other pumps. Pumps with pressure gauge can also be used for calibration. Pumps with exhaust valve vent air after use.

Styles D, E, and F have a reservoir to store test fluids.

Style G has a baseplate to provide leverage and stability while testing.

Electric Pumps for Testing

Easier to use than manual pumps, these use electricity to quickly pump water through your system so you can test for leaks. They are also known as hydrostatic test pumps. They are portable so they can be lifted and moved to any location.

Style B is protected by a metal cage with rubber feet; it includes a 10-ft. hose for high-pressure applications.

Air-Powered Pumps for Testing

These pumps use compressed air to pump water or hydraulic fluid at high pressures through your system for leak testing. They come with a regulator that shuts off the pump when the desired air pressure is met and restarts it when the pressure drops.

Style C has wheels for portability.

Low-Pressure Differential Gauges with U-Tube

Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure. They are commonly used to indicate clogged filters.

Magnet-mount gauges can be moved for use in multiple locations. Gauges with barbed tube connection have a flexible body that rolls up for storage or transport.

Low-Pressure Differential Gauges with Dial Indicator

Measure small changes in air pressure with these gauges. They are commonly used to indicate clogged filters and to monitor fans and blowers.

Service these gauges without removing them using air filter kits. Kits include two vent valves for releasing air.

Surface mounting brackets allow gauges to be quickly installed on any flat surface. L mounting brackets can be carried to wherever you need to take a pressure reading. They can stand alone or be hung. Wraparound mounting brackets make it easy to service tubing, and don’t require cutting a hole in the wall.

Medium-Pressure Differential Gauges

Popular for use with natural gas, these gauges measure pressure differences in pipelines and filters with a maximum pressure of 1,500 psi.

Gauges with 316 stainless steel case are more corrosion resistant than gauges with an aluminum case.

High-Pressure Differential Gauges

These gauges are able to withstand line pressures up to 3,000 psi. They are commonly used to measure pressure differences in pumps and filters.

Gauges with 316 stainless steel case are more corrosion resistant than gauges with an aluminum case.
