Boshart PG45 No-Lead Liquid-Filled Pressure Gauge, 0-160 PSI

Boshart PG45 No-Lead Liquid-Filled Pressure Gauge, 0-160 PSI

The Boshart PG45 is a no-lead, liquid-filled pressure gauge built for general-purpose water system pressure monitoring on the job site. It features a 0-160 PSI reading range and a lower-mount (LM) connection, making it a straightforward drop-in gauge for well systems, pump stations, hydronic loops, and other residential or commercial water lines where accurate, easy-to-read pressure feedback is needed at the point of connection. This gauge is available with a 2" or 4" dial face, so installers can match the gauge to the readability and panel-space requirements of the job while every size shares the same 0-160 PSI range, liquid-filled case, lower-mount connection, and no-lead construction. The gauge body is liquid-filled, which dampens needle vibration from pump cycling and pressure surges so plumbers and pump installers get a steadier, more reliable reading over the life of the installation compared to a dry-case gauge. As a no-lead component, the PG45 is manufactured to reduce lead content in the wetted pathway, an important consideration for potable water applications where every fitting and gauge in the line matters. Boshart notes that this gauge is general purpose and is NOT rated for use with oxygen service — installers should route oxygen or other incompatible gas lines to a gauge specifically rated for that media. The PG45 ships in cartons of 20 pieces per size, making it a practical stocking item for plumbing wholesalers, pump contractors, and service trucks that regularly replace or install pressure gauges on residential and light commercial water systems.
