Pressure gauge for pressure washers

The Aro 104493 is a commercial pressure gauge designed for pressure washer systems. It provides a primary pressure range of 0 to 160 psi for monitoring pump output. The gauge features a 1 1/2 inch dial with a white face for clear readability. It is built for general outdoor power equipment maintenance.

1/8 inch NPT center-back connection

The single specification that decides fit is the 1/8 inch NPT male process connection located at the center back. This thread size and orientation must match the port on your specific pressure washer pump or manifold. The socket material is brass for durability and corrosion resistance. Verify your equipment requires this exact connection type before purchasing.

Accuracy and durability under continuous use

The gauge maintains an accuracy of +/- 3.00 percent across the full 0 to 160 psi range during sustained operation. The bourdon tube sensor responds steadily to constant pressure without liquid filling. A polycarbonate lens and plastic case protect the movement from vibration and environmental exposure. The unit is not field fillable and is not designed for panel mounting.

Questions about this item

What does the 0 to 160 psi range mean when the gauge is installed on a pressure washer?

It shows the live water pressure from zero up to 160 psi so the operator can verify the machine is running within its normal working window.

What does the 1/8 in NPT male connection limit in practice?

The tapered NPT thread seals directly into a 1/8 in female port, so the gauge can only be mounted on fittings that provide that exact thread size and gender.

What does the centre-back mount and 1 1/2 in dial require for installation?

A clear hole behind a panel or bracket that accepts the 1/8 in NPT stem, with enough depth for the 1 1/2 in diameter case to sit flush without interference.
