Glycerine-filled pressure gauge 1/4" radial 0 - 40 bar

The glycerine-filled pressure gauge is suitable for gaseous and liquid, not highly viscous and non-crystallising media that do not corrode copper alloys. Due to the glycerine, the needle remains calm. That is why the pressure gauge is used for measuring points with strong vibrations and high dynamic pressure loads.

Note:
The volume of the glycerine can vary due to temperature fluctuations. This causes a change of the pressure balance between the inside and outside of the casing. That is why a vent plug (mini ball valve or rubber grommet) is used for the compensation of the pressure.
By default, the pressure gauge is supplied with closed vent plug. After the installation, the plug must remain open. Normally, a small amount of glycerine escapes until the pressure is compensated.
