Overview
The Bar in line kit for a pressure gauge lets you fit a gauge into the pressure line so the operator can check the actual working pressure. It is ideal for hydro excavation, where the listing notes it is used to make sure statutory pressure standards are not exceeded. The gauge is not included in this kit.
Plumbing a gauge into the line is a simple way to turn a pressure washer into a metered machine. Instead of guessing the output from the machine rating, the operator reads the live pressure at the gun or the excavation tool, which is the figure that matters for safe and compliant work. The kit is a straight forward addition to the delivery line and works with the machines in the range, either with a gauge already fitted or with the matching Bar gauge.

What You Need to Complete the Job
Pair the in line kit with the Bar gauge HVAC for a complete pressure reading setup, and keep the delivery line on a 92 metre hose reel for organised work. See the Pressure Washers Accessories range for the rest of the kit.
Frequently Asked Questions
Does the kit include the gauge?
No. The listing states the gauge is not included in this kit. The kit is the in line fitting that holds a gauge in the pressure line, and the Bar gauge HVAC is the matching gauge sold separately. A full kit with the gauge is also available as 125 85.305.001.
Why is it used for hydro excavation?
Hydro excavation uses high pressure water to dig, and the pressure has to stay within statutory standards for the tool and the site. The in line gauge lets the operator confirm the live pressure and adjust the machine so the standards are not exceeded.
How is it fitted?
The in line kit goes into the high pressure delivery line between the pump and the gun or tool, and the gauge screws into the kit. It is a permanent or semi permanent fitting that stays on the machine for ongoing pressure checks.
