Viking VWATERSF is a water pressure gauge designed to provide a clear local reading of pressure in fire sprinkler and fire-protection piping systems. Its 0–300 psi (20.7 bar) range helps technicians verify system pressure during inspection, maintenance and operational checks.

The gauge uses a 1/4-inch NPT connection and a plastic case with a clear viewing window, with a bronze Bourdon tube and brass socket. It is intended for use on suitable sprinkler risers, alarm-valve trim and other fire-protection pressure-monitoring points. Install in accordance with applicable codes and the system manufacturer's instructions.
