Ashcroft 25 1490A 02L 5 PSI Pressure Gauge

This Ashcroft low-pressure gauge measures 0 to 5 psi with a +/-2-1-2 percent accuracy class. It features a 2 1/2 inch nominal dial size with a white face and black polysulfone case. The instrument is rated IP54 for dust and water ingress protection.

1/4 in MNPT bottom connection for panel mounting

The gauge connects via a 1/4 inch male NPT thread located at the bottom. A 2.13 inch bolt circle diameter defines the mounting pattern. The polysulfone case and polycarbonate lens suit compatible panels without requiring liquid fill.

Dry operation with IP54 enclosure

The unit operates dry with no internal dampening fluid or vibration resistance features. The sealed IP54 case protects the movement from dust and splashing water in normal use. The glass-filled polysulfone body and polycarbonate lens maintain integrity without active cooling or power.

Questions about this item

How does the +/-2-1-2% accuracy hold up when the gauge is run continuously at 5 psi?

The Ashcroft 25 1490A 02L maintains its stated +/-2-1-2% accuracy across the 0 to 5 psi range with no dry dampening or vibration resistance features that would degrade under sustained pressure.

Does the polysulfone case and polycarbonate lens stay cool and quiet during all-day operation?

As a purely mechanical low-pressure gauge with no moving electronics, dampening fluid or vibration resistance, it generates no heat and produces no audible noise during continuous use.

What thread sealant or adapter do I need for the 1/4 in male NPT connection?

The 1/4 in MNPT bottom connection requires standard NPT thread sealant tape or paste and mates directly with any 1/4 in female NPT port; no proprietary adapter is needed.
