8700 Series Gauge
Acetyl 5 Bolt Gauge for Low-Pressure, Non-Heated Systems

General Information & Features
The magnetic construction permits the complete sealing off of the inside liquid from the outside gauge head and dial allowing quick dial replacement without the loss of liquid or time.
The dial pointer is silicone-dampened. All dials, senders, and switches are instantly replaceable — there are just two screws to remove and replace.
The rugged gear drive is standard with shrouded, stainless steel, beveled gears designed to shed and work out any loose particles that might jam the gear action. All materials have been selected to provide outstanding durability in water-gauging applications. Sealing between the gauge and the tank is achieved through the use of the 0015-00423 Buna-N gasket.
