Black aluminum test pressure gauge with 4 1/2 inch white dial and glass lens

Ashcroft

Ashcroft 45-1082PS 02L 10000 PSI Test Pressure Gauge 4 1/2 in

SKU CH-0AA3-TGB2Q

Measures pressure from 0 to 10000 psi with ±0.25% accuracy on a 4.5-inch mirrored dial in an aluminum case with 1/4 NPT bottom connection

  • TypeElectronic
  • +/- 0.25 % accuracy for precise readings
  • 0 to 10,000 psi range covers high-pressure tests
  • 4 1/2 in dial with mirror band eases parallax-free viewing
  • Aluminium case with glass lens resists harsh environments
  • 1/4 in NPT male bottom connection fits standard ports

Precision test gauge for 10 000 psi systems

The Ashcroft 45-1082PS 02L is a test pressure gauge built for verifying hydraulic and pneumatic circuits up to 10 000 psi. Its accuracy of ±0.25 % full scale suits calibration labs, field service engineers and quality inspectors who need traceable readings. The 4 1/2 inch dial with white mirror-band face reduces parallax error during critical checks.

Solid aluminium case with glass lens

The black aluminium case resists corrosion and mechanical shock in workshop environments. A glass lens protects the dial from solvents and debris while maintaining optical clarity. The gauge is not field-fillable and carries no IP or NEMA rating, so it should be shielded from direct wash-down or immersion during normal use.

Bottom 1/4 NPT male connection for panel mount

A 1/4 inch NPT male process connection at the bottom allows direct plumbing into test ports without extra adapters. The unit fits a 4.875 inch panel cut-out and a 5.375 inch bolt circle for secure flush mounting. No accessories, fill fluids or calibration certificates are bundled, so users must source fittings and verification paperwork separately.

Questions about this item

How do I install the 1/4 in NPT male connection on this 4 1/2 in test gauge, and what step is often missed?

Thread the 1/4 in NPT male process connection into the matching female port using PTFE tape or thread sealant rated for 10000 psi. The step often missed is tightening to the correct torque without over-stressing the aluminum case, which can distort the 4.875 in panel cut-out alignment.

What maintenance or replacement will the Ashcroft 45-1082PS gauge need over time?

The glass lens and aluminum case are not field-fillable, so fluid cannot be topped up. Plan to recalibrate against a primary standard at least annually to maintain the +/- 0.25 percent accuracy, and replace the unit if the bourdon tube shows fatigue or the mirror-band dial becomes illegible.

What limit appears first when this 10000 psi gauge runs continuously at high pressure?

Sustained operation near the 10000 psi upper range stresses the bourdon tube and aluminum case, causing gradual zero shift that degrades the stated +/- 0.25 percent accuracy before any leak or case rupture occurs.
