Wal-rich 1712812 Pressure Gauge 200 Psi 3.5 Inches Brass Lower Connection

Product Description

The WAL-RICH 1712812 is a 3.5-inch dial pressure gauge rated for 0 to 200 PSI. It is built for use in plumbing, HVAC, and general mechanical systems where reliable pressure monitoring is required. The gauge uses a Bourdon tube sensing element, which is the industry-standard mechanism for measuring fluid and gas pressure. As internal pressure rises, the curved Bourdon tube straightens slightly, and that movement is translated into a readable needle position on the dial face. This design is proven, durable, and widely trusted by plumbing and HVAC professionals across a broad range of applications. The 3.5-inch dial face provides a clear, easy-to-read display in the field. The lower connection is a 1/4-inch NPT brass fitting, which is a common thread size found on water lines, oil systems, gas lines, and many mechanical panels. Brass construction at the connection point resists corrosion and provides a dependable seal over time. The outer case is black steel, which gives the gauge durability in shop, mechanical room, and job site environments. This gauge is compatible with water, oil, and gas systems. It is not approved for use on oxygen systems. Trade professionals including plumbers, pipefitters, HVAC technicians, and maintenance mechanics rely on gauges like this one to verify system pressure, diagnose pressure loss, and commission new installations. The 0 to 200 PSI range covers most residential and light commercial water and gas pressure applications. Each package contains one gauge.

• Bourdon tube mechanism provides accurate and repeatable pressure readings from 0 to 200 PSI
