Commercial Pressure Gauge 0 to 3000 psi

This commercial pressure gauge measures from 0 to 3000 psi for monitoring water pressure in pressure washer systems. The 1 1/2 inch dial provides clear readings for operators who need to verify system pressure during use. It suits maintenance technicians and equipment owners who require a direct replacement gauge for compatible machines.

ABS plastic case with 1/8 in NPT bottom connection

The gauge case is made from black ABS plastic with an acrylic lens protecting the white dial. A male 1/8 inch NPT thread at the bottom allows direct mounting into a matching port without extra fittings. The fixed connection and non-fillable design mean the unit is installed once and left in place for continuous monitoring.

Accuracy tolerance and environmental limits

Accuracy follows a +/-3-2-3 percent grade across the scale, so readings near mid-range are tighter than those at the extremes. No IP or NEMA rating is assigned, and the gauge offers no vibration resistance or liquid dampening. Buyers who need a sealed, vibration-rated instrument or a fillable case for pulsating pressure should select a different model.

Questions about this item

What accuracy range does the +/-3-2-3 percent spec cover across the 0 to 3000 psi dial?

The gauge reads within +/-3% of full scale in the first and last thirds of the 0 to 3000 psi range and +/-2% in the middle third.

What thread and mounting orientation are required for the 1/8 in NPT connection?

A male 1/8 in NPT fitting threads into a female port with the gauge body facing downward from the bottom-mounted connection.

How is the dry commercial gauge installed without liquid fill, and what step is often missed?

Thread the 1/8 in NPT male end into the port using a wrench on the case flats, not the dial, and do not over-tighten the ABS housing.
