Boshart - PG-200-GNL - 2" Dial Pressure Gauge (Liquid Filled, Lower Mount, 1/4'' NPT)
Boshart - PG-200-GNL - 2" Dial Pressure Gauge (Liquid Filled, Lower Mount, 1/4'' NPT) is backordered and will ship as soon as it is back in stock.
2" Dial - 1/4'' MPT Lower Mount Pressure Gauge ,Black Steel Brass, Liquid Filled, 0-200 PSI
Application:
General purpose gauge, for potable water pumps & systems, these gauges are suitable for compressors, hydraulic presses, machinery, pneumatic equipment and motors, for most commercial air, water and steam services. To be used with fluid medium which does not clog connection or corrode copper alloy.
Not for use with oxygen, natural gas or propane
IMPORTANT: Liquid Filled Gauges are sealed with a rubber plug to prevent leaking during shipment. Upon installation the tip of the plug must be cut off in order for the gauge to vent, a small hole allows for equalization of the internal gauge pressure to the atmospheric pressure.
FAILURE TO DO SO WILL ADVERSELY EFFECT THE FUNCTION OF THE GAUGE.
Glycerin Temperature Rating: Gauges are filled with 99.7% concentration glycerin, which starts to become viscous at +63°F (17°C). As the temperature decreases, the more viscous glycerin becomes, which causes the pointer to move slower to its correct position. At 23°F (-5°C) these gauges will no longer operate. For operating temperatures lower than 23°F (-5°C), glycerin should be mixed 2 parts glycerin with 1 part water (66.7% concentration) which lowers the freezing point allowing the gauge to be used in temperatures as low as -51°F (-46°C).
