Ashcroft 451279 4 1/2in 0-30 psi Pressure Gauge

This Ashcroft process pressure gauge features a 4 1/2 inch dial with a white face and black phenolic case. It measures pressure from 0 to 30 psi with an accuracy of +/- 0.5 percent. The unit is designed for industrial process monitoring applications requiring reliable dry-case performance.

Verify 1/2 in NPT male connection

Before ordering confirm that your system uses a 1/2 inch NPT male process connection at the bottom entry point. The gauge is not field fillable and carries no IP or NEMA rating so ensure the installation environment suits a dry dampened instrument. Check that the 0 to 30 psi range matches your required operating pressure.

Phenolic case with glass lens and PLUS!

The black phenolic case provides chemical resistance while the glass lens protects the dial. A dry PLUS! Performance feature dampens vibration without liquid fill reducing maintenance needs. The bottom mounted 1/2 inch NPT male connection allows direct inline installation on compatible piping or equipment.

Questions about this item

What comes in the box with the Ashcroft 451279 and what must be bought separately?

The gauge ships as a single unit with a 4 1/2in dial, 1/2in male NPT bottom connection, glass lens and dry PLUS! Performance vibration-dampened case. Thread sealant, fittings or a mounting bracket are not included and must be sourced separately.

Which version of the 451279 should I choose for a 0 to 30 psi application?

The 451279 is offered in one configuration for this range: 4 1/2in phenolic case, +/- 0.5 percent accuracy, 1/2in male NPT bottom connection, glass lens, white dial and dry PLUS! Performance dampening. No alternative pressure spans or connection sizes are listed for this model.

What does the +/- 0.5 percent accuracy mean when the gauge is installed on a live 0 to 30 psi line?

The reading will stay within half a percent of full scale across the 0 to 30 psi span. The dry PLUS! Performance case dampens vibration without liquid fill, and the glass lens resists scratches in harsh environments.
