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.

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.

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.
