Square Boiler Gauge 0-200 PSI

This square boiler gauge measures pressure from 0 to 200 psi and temperature from 80 to 320 degrees Fahrenheit. It features a steel case with glass lens and brass or bronze wetted parts. The lower back connection uses 1/2 inch MNPT threads. Pressure accuracy is rated at +/-3-2-3 percent while temperature accuracy is +/-3 percent.

Suits boiler monitoring tasks

Operators who need simultaneous pressure and temperature readings on hydronic or steam boilers will find this gauge suitable. The square case fits standard panel cut-outs for boiler rooms and mechanical spaces. Installers requiring a different connection orientation or a wider pressure range should look at other gauge configurations.

Steel case with glass lens

The steel case and glass lens provide durability in boiler environments where heat and moisture are present. Brass or bronze wetted parts resist corrosion from treated water. These material choices extend service life compared to gauges with plastic lenses or steel wetted parts. The lower back mount simplifies installation against a panel or pipe fitting.

Questions about this item

What pipe thread size do I need to mount this 1/2 in MNPT gauge?

The gauge uses a 1/2 in MNPT lower-back connection, so your piping must provide a matching 1/2 in female NPT fitting.

Will the 3 11/16 in square case fit the same panel cut-out as my old round gauge?

The case measures 3 11/16 in high by 3 11/16 in wide, requiring a square cut-out rather than the round hole used by many older gauges.

How can I verify the needle reads correctly once installed?

At ambient temperature the pointer should sit near 80 °F and 0 psi; when the boiler reaches operating temperature it should track within ±3 % of 320 °F and ±3-2-3 % of 200 psi.
