Value Brand 4FLW2 Commercial Pressure Gauge 0 to 200 psi 2 1/2 in Dial 1/4 in NPT

Commercial pressure gauge for general use

This commercial pressure gauge measures from zero to 200 psi and features a two-and-a-half-inch dial with a 1/4-inch NPT male bottom connection. It is suited to technicians who need a straightforward mechanical indicator for air, water or oil lines in workshop or light-industrial settings.

Accuracy limits and environmental constraints

The gauge uses a bronze sensor and brass socket housed in an ABS plastic case with an acrylic lens. Accuracy follows a 3-2-3 percent pattern across the scale. The product carries no IP or NEMA rating and no hazardous-location rating, so it must be kept away from wash-down, dust ingress or explosive atmospheres.

Check connection and chemical compatibility

Verify that your system uses a 1/4-inch NPT female port at the mounting point before ordering. The bronze sensor and brass socket must be compatible with the process fluid to avoid corrosion. California Proposition 65 warnings apply because the gauge contains chemicals identified by the state as causing cancer and reproductive harm.
