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.

Gauge Siphon Tubes
A
B
C
D
Also known as pigtails, these siphon tubes protect dry gauges from steam and high-temperature fluids. Add water to the tube to create a protective barrier between your gauge and process media.
Style C requires less maintenance than Styles A, B, and D because the extra bends prolong water retention.

Gauge Guards
316 Stainless Steel Guard
316 Stainless Steel Guard With Drain Port
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.
Guards with drain port allow you to remove process media.
