Pressure Gauge for Pressure Washers

This Global Industrial 1-1/2 inch pressure gauge measures up to 100 PSI with dual KPA and CM2 scales. It uses a 1/8 NPT center back mount for direct installation on compatible pressure washer pumps and regulators. The gauge is new and built to ASME 3/2/3% accuracy standards.

Type 111.12 Construction Details

The Type 111.12 design provides a black plastic case with a snap-in plastic window for durability. Its center back mount rear connection allows straightforward plumbing into existing systems. This construction suits demanding applications such as compressors, valve positioners, and pneumatic controllers.

100 PSI Maximum Reading Decides Fit

The 100 PSI upper limit determines whether this gauge matches your equipment's operating range. Systems requiring higher pressure readings need a different gauge. Buyers needing a lower range or a different connection thread should select another model.

Questions about this item

Does the plastic window on this 111.12 gauge yellow or crack over time?

The snap-in plastic window may discolour or become brittle after prolonged exposure to UV and cleaning chemicals; inspect it during routine maintenance and replace the gauge if readability is impaired.

At what pressure does the ASME 3/2/3% accuracy limit become the limiting factor?

Accuracy is stated as 3/2/3% of the 100 PSI span, so the tolerance band remains the limiting factor across the full 0-100 PSI range rather than at a single pressure point.

How hot does the black plastic case get when the gauge runs at 100 PSI all day?

The case temperature will track the fluid temperature; with 100 PSI water or air the plastic typically stays near the media temperature and does not generate additional heat of its own.
