Purpose and user

The Ashcroft 1188 low-pressure gauge measures from 0 to 20 psi on a 4 1/2 in dial. It suits technicians who need a clear, analogue read-out for pneumatic or hydraulic checks. The phenolic case and glass lens resist workshop solvents and impacts. A 1/4 in NPT male bottom connection threads directly into standard test ports.

Interface limits

The 1/4 in NPT male thread seals with tape or compound and fits common port sizes. Accuracy follows a +/-2-1-2 percent grade across the scale, so readings near mid-range are tightest. No IP or NEMA rating is declared, so the gauge should stay dry and free from pressurised wash-down. The case is not field-fillable, limiting use to dry media only.

Upgrade context

This unit replaces gauges with smaller dials or looser accuracy grades where misreading costs downtime. The 5.38 in bolt circle matches many panel cut-outs, easing retrofit without new drilling. It is not for systems above 20 psi, for filled-case damping, or for environments that demand a certified ingress rating.

Questions about this item

How do I choose between the available versions of the Ashcroft 1188 gauge?

The Ashcroft 1188 is offered as a single configuration with a 0 to 20 psi range and 4 1/2 inch dial, so no version selection is required.

What does the 0 to 20 psi range mean when the gauge is installed on a live system?

It measures pressures from zero up to 20 psi with an accuracy of ±2-1-2 percent across the scale, suitable for low-pressure air, gas or liquid lines.

What does the 1/4 inch NPT connection limit in practice?

The male 1/4 inch NPT bottom mount fits standard low-pressure ports and the phenolic case is not IP or NEMA rated, so it is intended for protected indoor installations.
