Value Brand Commercial Pressure Gauge 4FMN1 0 to 30 psi 2 1/2 in Dial 1/4 in NPT

Commercial Pressure Gauge 0-30 psi

The Value Brand commercial pressure gauge measures from zero to 30 psi with a 2 1/2 inch dial and a 1/4 inch male NPT bottom connection. It is built for technicians who need a direct-reading instrument on plant air, water or hydraulic lines. The case and wetted parts are 304 and 316 stainless steel for corrosion resistance. The acrylic lens protects the dial in workshop conditions.

+/-3-2-3% accuracy class

Accuracy follows a +/-3-2-3 percent grade across the scale, which is the single figure that determines whether this gauge meets your test specification. The sensor and socket are both 316 stainless steel, so the wetted path suits media compatible with that alloy. The gauge carries no IP or NEMA rating and is not rated for hazardous locations, so sealing and area classification must be verified separately.

For maintenance crews needing a bottom-mount

This unit suits maintenance crews who need a bottom-mounted commercial gauge with a standard 1/4 inch NPT thread and no panel-mount requirement. Buyers who need a panel-mountable case, an IP-rated enclosure, a hazardous-location rating or a different pressure range should look at other models. The product carries a California Proposition 65 warning for cancer and reproductive harm.
