Commercial Pressure Gauge 0-300 psi

This commercial pressure gauge measures from 0 to 300 psi with a 2 1/2 inch dial and 1/4 NPT male bottom connection. It is built for technicians and maintenance teams who need a reliable mechanical instrument for general-purpose pressure monitoring on compatible systems.

Accuracy and Construction Materials

The gauge delivers an accuracy of +/-3-2-3 percent using a 316 stainless steel sensor and socket housed in a 304 stainless steel case with an acrylic lens. No IP or NEMA rating and no hazardous-location rating are provided, so the unit is intended for standard indoor or sheltered environments.

Panel-Mount Limitations

This model is not panel-mountable, which limits installation to direct line mounting rather than enclosure integration. Buyers who need a flush-mounted instrument or a different pressure range should look elsewhere. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

How do I install the 1/4 NPT bottom connection without cross-threading?

Wrap PTFE tape on the male threads, start the gauge by hand until snug, then finish with a wrench on the 304 stainless case flats — never force the 316 stainless socket.

Which part will need replacement first under normal use?

The acrylic lens scratches more easily than the 316 stainless sensor or socket, so plan to replace the lens if readability drops.

What limit appears first during continuous 300 psi cycling?

The +/-3-2-3 percent accuracy band is the first constraint; sustained cycling at full scale can push readings outside that tolerance.
