What this gauge does and who uses it

The Ashcroft 45-1082PS 02L is a new test pressure gauge built for technicians who need to verify system pressure accurately. Its 0 to 600 psi range suits hydraulic and pneumatic calibration tasks. The 4 1/2 in dial with a white mirror-band face reduces parallax error during reading. It mounts through a 4.875 in panel cut-out with a 5.375 in bolt circle.

The spec that confirms fit

The process connection is a 1/4 in male NPT thread located at the bottom of the case. This single detail decides whether the gauge threads directly into your test port or requires an adapter. The aluminum case and glass lens are fixed attributes, and the unit is not field fillable.

Behaviour under sustained load

Accuracy is held to +/- 0.25 percent of span across the full 600 psi range, not just at mid-scale. The mirror-band dial maintains consistent readability during extended test cycles. With no IP or NEMA rating, the gauge is intended for protected indoor use where condensation or wash-down are not factors.

Questions about this item

What does the ±0.25 % accuracy mean when the gauge is installed on a live system?

The reading will stay within a quarter of one percent of the 600 psi full scale across the entire range.

How does the 1/4 in NPT male connection limit the pressure rating in practice?

The 1/4 in NPT male thread is rated to the gauge's 600 psi maximum, so the connection does not reduce the usable range.

What panel cut-out and bolt pattern are needed to flush-mount the 4 1/2 in dial?

Cut a 4.875 in diameter hole and use the 5.375 in bolt circle for the mounting studs.
