Ashcroft 4.5-Inch Test Gauge

The Ashcroft 45-1082AS is a new test pressure gauge built for professionals who need precise readings up to 30 psi. Its 4.5-inch dial features a white face with a mirror band to eliminate parallax error. Accuracy is rated at +/- 0.25 percent of span. The aluminum case and glass lens suit panel-mount installations.

Verify Panel Cut-Out and Connection

Confirm your panel cut-out measures 4.875 inches to accept the gauge body. The process connection is a 1/4-inch male NPT thread located at the bottom. Ensure your system uses compatible NPT fittings and that the 30 psi range covers your normal operating pressure without exceeding the scale.

Panel Mount with Male NPT Fitting

The gauge mounts through a panel using a 5.375-inch bolt circle for secure fastening. The bottom-mounted 1/4-inch male NPT connection allows direct plumbing without extra adapters. The case is not field-fillable and carries no IP or NEMA rating, so protect it from wash-down or outdoor exposure.

Questions about this item

What does the Ashcroft 45-1082AS gauge include and what must I supply?

The gauge arrives as a complete unit with a 4 1/2 in dial, glass lens, aluminum case and a 1/4 in male NPT bottom connection. You will need to provide the panel cut-out of 4.875 in and the mounting bolts for the 5.375 in bolt circle.

How do I choose between the available range options for this model?

This specific model carries a single primary range of 0 to 30 psi with a white mirror-band dial. Select it when your test pressure falls within that span; other ranges would require a different part number.

What does the +/- 0.25 percent accuracy mean when I am reading 30 psi on the job?

At the top of the scale the true pressure can be up to 0.25 percent of full scale different from the needle indication, so the reading at 30 psi reflects that tolerance.
