316 Stainless Steel Guard
316 Stainless Steel Guard With Drain Port
Plastic Guard
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.

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 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 Vibration Dampers
Also known as snubbers, these reduce the flow of fluids into your pressure gauge to damper vibration, pulsation, and pressure spikes. The smaller the orifice, the greater the reduction in flow.
Dampers with filter disc prevent damage to your gauge by trapping particles in your process media.
Dampers with five orifice inserts allow you to change the level of vibration and pressure damping as needed; remove the set screw to exchange inserts and then replace the set screw to use.

Vibration-Resistant Pressure Gauges for Chemicals
Bottom Connection
These gauges have a glycerin-filled dial that reduces needle flutter for precise readings in high-vibration applications reaching 2,000 psi. A 316 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 pressure.
