How to correctly install a pressure gauge

Pressure gauge: 

The pressure gauge is a device which monitors the performance of parameters. Its main work is to run the water through tanks under pressure. It also checks the errors and defects in the system. The pressure gauge measures the force of pressure in the water and air.

China hydraulic gauges supplier deals with the best quality of the gauges. You can buy the gauges from there. And the prices of the gauges are also reasonable. 

Things to be included in the pressure gauge:

Pressure gauges are made with the help of many tools. Some of them are the case, socket, welding style, display, digital pressure gauge, window, etc. China’s hydraulic gauges supplier uses the best material.

Types of pressure gauge:

There are many types of pressure gauges. It varies according to size, shape, material, and style. The types are:

  • Mechanical pressure: 

This is the pressure which is measured by the diaphragm, bellows, or with the Bourdon tube. Bourdon tube is the tube which converts the fluid pressure into the force. 

  • Hydrostatic pressure: 

This is the pressure which is generated by the liquid’s weight. The liquid’s height influences this pressure. And the properties of the hydrostatic pressure are influenced by gravity, and liquid density.

Dynamics of pressure: 

  •  Absolute pressure: 

When pressure is measured with the vacuum then it is known as absolute pressure.

  •  Differential pressure:

This is the pressure which measures the difference between the applied pressure. 

  • Gauge pressure:

This pressure is similar to the atmospheric pressure. When it is above the atmospheric pressure then it is positive. And it becomes negative when it comes below the atmospheric pressure.

Steps to install pressure gauge:

When we are installing a pressure gauge then one must do it properly. It is necessary for a person that there will be no defect in the installation of the pressure gauge. Because if there is a defect in the installation process then it may harm things. Some of the steps are as follows:

How to correctly install a pressure gauge
  1. Choose the right pressure gauge:

Before pulling a wrench you must check it properly. It is a must that you will choose the right gauge for the application. You must check its temperature process, processing compatibility, and other operating conditions.

You have to install the pressure gauge correctly. Otherwise, it leads to the same problem that you are tackling before it. So, choose the pressure gauge which perfectly fits all the things. For the quality material you can contact China hydraulic gauges suppliers.

  1. Wrench flats:

After choosing the right pressure gauge the next step is to install it properly. For this, you have to focus on the things which help in its installation. You can use an open-end wrench for applying the force on the wrench flat. The one who is applying the force must apply it appropriately. The excess applying of the force will result in leakage. It may damage the internals of the gauge.

  1. Seal:

The next step is to seal the deal. You must check the threads on the pressure gauge before sealing them. There are many types of threads such as parallel threads, tapered threads, etc. If your pressure gauge is having tapered threads some additional means of sealing are recommended. This type of sealing does not cover the whole. And if your gauge is having parallel threads you can seal it with the rings, or washers.

  1. Clamp socket/ union nut:

After sealing the deal further you have to use a union nut with the straight thread. This allows a convenient orientation for the face of the gauge. Rings are preferred for the adjustable orientation of the gauge. You have to tighten the gauge with the help of your hand. After it, you can apply the open-end wrench to the flat. 

  1. Blow-out space:

 Some gauges are present in designs and patterns which have a solid wall for personal safety. These gauges are present in between the Bourdon tube and the face of the gauge. Protection is a must because the event of pressure gauge builds pressure in the Bourdon tube. And all of the pressure gauges are directed to the back. You must keep a distance of 1/2 inches. 

  1. Gauge case:

There are some of the gauges which come with a small value on the top. It confuses the people why it is included. There will be all heat pressure inside the gauge during the shipment. And it will result in the gauge pointer to be off zero. Within the installation, you must open this vent to allow the pressure out. 

And it must be closed after the process. 

It is a must that you install the pressure gauge properly. 


A pressure gauge is the one that maintains the pressure of the air in the water system. One can read the pressure through many ways. Many things are involved in the maintenance of pressure gauges. So that it works properly and effectively. This allows you to install your pressure gauge in a good manner. You must check all the things before getting a pressure gauge to the last step of the installation.
