Wika model 213.40 is an ideal choice for OEM and general industrial applications requiring an economical liquid-filled pressure gauge. When vibration and/or pulsation are present, the glycerin fill dampens the bourdon tube and minimizes pointer oscillation, which reduces wear on the gauge movement. Model 213.40 is available in 2-1/2" and 4" sizes, in either 1/4" or 1/2" NPT Copper Alloy connections and is weather tight (NEMA 4X / IP 66). The case is gold-plated forged brass with integral connection and vent plug. The 2-1/2" size comes with gold-plated ABS cover ring and the 4" size comes with chrome-plated brass cover ring. The dial is white aluminum with black lettering, 2-1/2" size with stop pin and the pointer is black aluminum. The window is acrylic with Buna-N gasket.
General applications include:
- Adverse service conditions where pulsation or vibration exists
- Suitable for gaseous or liquid media that will not obstruct the pressure system
- Hydraulics and compressors
