Ashcroft 451379 0-15 psi Process Gauge

The Ashcroft 451379 is a process pressure gauge with a 4 1/2 inch dial and a 0 to 15 psi range. It offers +/- 0.5 percent accuracy and an IP66 NEMA 4X rating. The aluminium case and glass lens suit industrial environments.

Suits operators needing accurate low-pressure

This gauge fits applications that require precise measurement up to 15 psi with a large, readable dial. It is not intended for users who need higher pressure ranges or digital output signals. Buyers requiring different connection sizes or fill types should look elsewhere.

Straightforward bottom-mount installation

The 1/2 inch male NPT bottom connection allows direct mounting into standard process ports. The field-fillable design permits liquid addition on site for vibration resistance. Ensure thread sealant is compatible with the process media to avoid leaks.

Questions about this item

Does my process piping need a 1/2 in male NPT connection for the 451379 gauge?

Yes, the gauge has a 1/2 in male NPT bottom connection so the pipe or fitting must accept that thread size and gender.

Can the 4 1/2 in dial gauge replace an older 0 to 15 psi gauge with the same connection?

The 451379 matches a 0 to 15 psi range and 1/2 in male NPT bottom mount, so it fits existing piping with identical specs.

How do I confirm the 451379 is reading correctly after installation?

Apply a known reference pressure within the 0 to 15 psi span and verify the pointer indicates within +/- 0.5 percent of full scale.
