DESCRIPTION

U.S. Gauge P-1590 and R-1590 sprinkler gauges are de­signed for use on wet or dry sprinkler systems. These
3-1/2" gauges are approved by the Factory Mutual Sys­tem and are listed by Underwriters’ Laboratories. The
R-1590 retarded air gauge is used on the sprinkler head
side of the control valve in a dry system to accurately
monitor line air pressure, and also has the ability to ac­cept water pressure up to 250 psi upon system activa­tion. The P-1590 is used on the water supply side of
the system to indicate available source pressure, and is
used alone on wet systems where water is available to
the sprinkler head at all times. Private labeling is avail­able for OEM customers.
