Aro 104500 Pressure Gauge

The Aro 104500 is a commercial pressure gauge with a 2 in dial displaying 0 to 160 psi. It features a centre back 1/8 in NPT male brass connection and a polycarbonate lens. The black plastic case houses a bourdon tube sensor with +/- 3.00 percent accuracy.

Suits pressure washer monitoring

This gauge fits users needing a direct-mount, non-liquid-filled indicator for compatible fittings. It is not field-fillable and cannot be panel-mounted. Buyers who need a liquid-filled case for vibration damping or a panel-mountable design should look at something else.

Bourdon tube maintains steady reading under

The mechanical sensor responds consistently across the 0 to 160 psi range during sustained operation. Accuracy remains within the stated +/- 3.00 percent without the damping variation seen in liquid-filled alternatives. The fixed centre back connection ensures a stable mount throughout extended use.

Questions about this item

What fitting does my pressure washer need to accept the 1/8 in NPT center-back connection on this gauge?

Your pressure washer must provide a female 1/8 in NPT port so the gauge's male brass socket can thread directly into it.

Will the +/- 3.00 percent accuracy of this ARO 104500 gauge still be reliable if I keep using my older pump and hose?

Yes, the gauge's rated accuracy is independent of pump age; it will read system pressure within +/- 3.00 percent as long as the connection is leak-free.

How can I confirm the gauge is working correctly once installed?

Pressurise the system and verify the needle moves smoothly across the white 0 to 160 psi dial and returns to zero when pressure is released.
