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.
Gauges with 304 stainless steel case or ABS plastic case have better corrosion resistance than gauges with brass or steel case.

Maximum-Indicating Vibration-Resistant Pressure Gauges






These gauges have a red needle that indicates the highest pressure reached since the last setting. They have a glycerin-filled dial that reduces needle flutter for precise readings in high-vibration applications. Use them with pumps, filters, regulators, and in process lines to measure and display pressure. Mount gauges with the dial face upright.

Gas Pressure Gauges


Use these gauges with pumps, filters, regulators, and in process lines to monitor the pressure of compressed gas. Mount them with the dial face upright. Gauges for use with acetylene can also be used in welding applications.
Gauges with brass case are cleaned to meet ASME B40.1, Level IV for oxygen service.

Low-Pressure Gauges for Chemicals




A plastic or stainless steel guard, also known as an isolator, protects the gauge from damage caused by corrosive chemicals. Use them with pumps, filters, regulators, and in process lines to measure and display pressures.
Polypropylene and 316 stainless steel guards are more chemical resistant than PVC and CPVC guards.

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.

Absolute Pressure Gauges


Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure. They’re often used in laboratory applications, and they are barometrically independent.
Stainless steel gauges have excellent corrosion resistance, so they can be used with more corrosive liquids and gasses than gauges with a brass connection and aluminum case.

Sanitary Gauge Guards

Keeping corrosive substances from touching pressure gauges used in food-processing and pharmaceutical plants, these guards have a sanitary design. Made of 316 stainless steel, they won’t rust from frequent washdowns with harsh cleaners and sanitizers. They have continuously-welded seams and polished surfaces, so there aren’t any pits for bacteria to grow in. Removing them for cleaning and maintenance is easy thanks to their quick-clamp connection, which is sometimes called a tri-clamp.
Also known as isolators and diaphragm seals, these guards have a 316 stainless steel gasket to shield the pressure gauges from corrosion. Before use, fill the guards with fluid such as glycerin or silicone that’s suitable for food contact.

Gauge Guards



Also known as isolators or diaphragm seals, these protect gauges from corrosive process media. Fill guards with ISO Grade 32 hydraulic oil (not included) before use.
316 stainless steel guards provide excellent corrosion and chemical resistance and can handle higher temperatures and pressures than plastic guards.
Polypropylene and PVDF guards are more chemical resistant than PVC and CPVC guards.
Guards with drain port allow you to remove process media.
