Test Gauge for 0–300 psi Range

The Ashcroft 30-1084S 02L is a test pressure gauge built for measuring pressure from 0 to 300 psi. Its 316L stainless steel case and polycarbonate lens suit industrial and automotive technicians who need a reliable instrument for system verification. The white dial with mirror band aids precise reading.

Accuracy and Environmental Tolerance

The gauge delivers an accuracy of +/- 0.50 percent across the primary range. The 316L stainless steel construction resists corrosion in harsh environments while the polycarbonate lens protects the dial face. No liquid fill is present so the movement operates dry.

1/4 Inch NPT Bottom Connection

A male 1/4 inch NPT process connection at the bottom allows direct mounting to test ports or manifolds. The case is not panel-mountable and is not field fillable so installation is limited to inline or stand-mounted use. The 3 inch nominal dial size keeps the instrument compact for tight access points.

Questions about this item

How do I install the 1/4 in NPT male bottom connection without stripping the threads?

Apply PTFE tape or pipe sealant to the male threads, thread the gauge into the port by hand until snug, then tighten with a wrench on the 316L stainless steel wrench flats — do not turn the case itself.

What maintenance will the dry polycarbonate lens and 316L stainless steel case require over time?

Wipe the lens with a soft cloth and mild detergent; inspect the case and NPT threads for corrosion or damage during periodic calibration checks.

At what point does the +/- 0.50 percent accuracy spec become unreliable under continuous 300 psi cycling?

The gauge maintains its rated accuracy across the full 0 to 300 psi range; sustained cycling at the upper end does not introduce a separate drift limit beyond the stated tolerance.
