The A25DPG-30 Differential Pressure Swichgage® is a 2.5" (64 mm) dual-scale dial, diaphragm-actuated differential pressure-indicating gage. THIS GAUGE DOES NOT HAVE CONTACTS. The A25DPG-30, with a pressure range of 0-30 psi, is intended to monitor and indicate oil, fuel or water filter restriction and can reduce the risk of dangerously high pressure which may rupture the filter, resulting in contaminants entering the system. This filter restriction Swichgage® will let you know when to change your filter and maintain peak efficiency.

The gage mechanism is enclosed in a polycarbonate, break-resistant case and lens. A polished stainless steel bezel and O-ring seals help protect this rugged instrument from the external environment. Accuracy and protection from moderate overpressure is assured by a unique, unitized diaphragm chamber. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning. Inside the A25DPG-30, the tempered nickel silver gage pointer acts as a pressure indicator.
