Technical information
Advantage of glycerine filling
Filling with glycerine is ideal for high, dynamic shock and vibration loads. The liquid has a damping effect and relieves the mechanical components of the pressure gauge. A glycerine-water mixture is suitable for most applications and ambient temperatures. The pressure gauge housing is not completely filled, as the glycerine-water mixture absorbs additional water depending on the humidity and ambient temperature and expands accordingly.Shortcuts
- No pointer fluttering
- No damage to the mechanics
- No fogging of the dial
- Mechanics are constantly in protective and lubricating fluid

Pressure gauge V2A stainless steel with glycerine filling, size 4", connection stainless steel V2A male thread radial 1/2",
Our high-quality pressure gauge with V2A stainless steel housing and glycerine filling as a 4 inch version for applications where the display should always be in view and easy to read due to its size. The external connection thread is made of V2A stainless steel and is used where brass is not desired or cannot be used.
The connection - 1/2" BSP G threaded connection - made of V2A stainless steel is directed radially downwards. The pressure gauge is filled with approx. 80 - 90% glycerine so that the mixture can expand with temperature fluctuations. The glycerine filling allows the needle to remain steady, which is extremely advantageous in the event of vibrations and frequent pressure changes. A maximum deflection of the needle - pressure peaks or shocks that occur - is slowed down, so that the glycerine filling prevents possible damage to the Bourdon tube mechanism in pressure gauges and thus counteracts material fatigue and malfunction. The rubber nipple used is cut on or off so that pressure equalization takes place.
The high accuracy class of 1.6 (max. 1.6% deviation from the measured value) enables an exact reproduction of the prevailing pressure value. In tough applications, possibly in humid environments, with oily or corrosive media, the V2A stainless steel housing of the pressure gauge is the better choice than a conventional steel housing.
Pressure gauges are also known as pressure meters and are used to measure the pressure in liquids and gases. On the one hand, this indicates whether the desired pressure has been reached or the display warns of a possible overpressure, which could lead to damage to system components.
