Gauge Guards
Also known as isolators or diaphragm seals, these protect gauges from corrosive process media. Fill guards with 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.
