This is a Neptune Benson pressure and vacuum gauge combination with a 1/4 inch NPT bottom mount and is designed with a stainless steel case and shatter resistant crystal. The dial is made of heavy gauge aluminum with black lithographed lines and numerals on a white background. This combination pressure gauge is designed to read up to 60 PSI and 30 inch vacuum. These gauges are designed for Neptune Benson filters.
A swimming pool pressure gauge displays the exact pounds per inch (PSI) of your pool filter, which requires some pressure inside its tank to operate. When the filter pressure is normal, water is flowing through it fairly seamlessly and your equipment is operating smoothly and safely.
