Industrial Pressure Gauge 0–15 psi

The Ashcroft 251009 is a new 2 1/2 inch dial gauge built for measuring pressures from 0 to 15 psi. Its 304 stainless steel case and polycarbonate lens meet IP54 when the vent plug is open and IP65 or NEMA 4 when closed. The 1/4 inch NPT male lower-back connection suits panel or pipe mounting in industrial and automotive test setups.

Replaces worn or uncalibrated analog gauges

Swap it in when an existing gauge shows drift beyond the stated ±1.0 percent accuracy or when the case has corroded. The PLUS! Performance dampening steadies the needle on pulsating systems, so the upgrade is worth it whenever vibration makes readings hard to trust.

Suits technicians needing a rugged 0–15 psi

It fits users who require a stainless, field-serviceable instrument with a clear polycarbonate face and standard 1/4 NPT fitting. Buyers who need a different pressure span, a larger dial, a front-flange mount or a filled case should look at other models.

Questions about this item

What size NPT fitting does the 2 1/2 in gauge need for mounting?

The process connection is a 1/4 in male NPT thread, so the panel or pipe must accept that exact size.

Which step is often missed when installing the lower back mount?

The vent plug must be opened or closed to match the required IP54 or IP65 rating before the gauge is pressurised.

When will the polycarbonate lens need replacement?

Replace the lens if it becomes clouded, cracked or scratched enough to hide the 0 to 15 psi scale.
