How to Quick Disconnect a Hydraulic Pressure Gauge

A hydraulic pressure gauge is an instrument that measures the operating pressure within a mechanical system that contains a liquid medium such as water or oil. As such, the points at which they are coupled to the system in question are normally tightly secured and take some time to disassemble. However, if you do not intend for your pressure gauge to be a permanent fixture in your system, you can install a quick release coupling that will allow you to connect and disconnect the gauge with one movement of the hand.

Instructions

    • 1

      Shut off the power to your device so that its liquid medium is not moving through the system.

    • 2

      Unscrew the valve fitting housing the pressure gauge and remove both the gauge and the valve. The valve fitting is the threaded screw-shaped casing around the base of the T-joint connecting the gauge to the larger pipe.

    • 3

      Screw the quick release coupling into the valve housing (the threaded base of the T-joint exposed when you unscrewed the valve fitting in the previous step). The coupling will come with self-acting valves to stop fluid loss when you disconnect the gauge, as well as air inclusion when you reconnect it. Tighten the coupling's screw and ensure that it is secure in the valve housing.

    • 4

      Screw the pressure gauge back into the free end of the quick release coupling. Tighten the gauge's screw and ensure that it is secure in the coupling.

    • 5

      Push and twist the outer sleeve of the quick release coupling to remove the pressure gauge in a single movement.
