Overview
The Wika 9767142 is a liquid-filled mechanical pressure gauge designed for industrial applications requiring accuracy and durability in challenging environments. This model 213.53 features a 2.5″ dial with a 0–2000 PSI scale and a 1/4″ NPT lower-mount connection. The liquid-filled model 213.53 mechanical Bourdon tube pressure gauge is constructed with a case from stainless steel and wetted parts from copper alloy.
Key Features
- Stainless steel case for protection in harsh environments; when filled, excellent for high vibration and pulsation applications
- O-ring seal around the connection makes this gauge field liquid fillable
- Accuracy: ±2.5% of span ASME B40.100 Grade A
- Glycerine liquid fill; white dial with black lettering; polycarbonate window
- Blow-out device for safety—overpressure can escape in case of failure
- IP65 ingress protection; suitable for a wide range of industrial applications
Technical Specifications

Typical Applications
Intended for adverse service conditions where pulsating or vibration exists; suitable for all gaseous and liquid media that will not obstruct the pressure system or attack copper alloy parts. Common uses include:
- Hydraulic system monitoring
- Air compressor pressure measurement
- Equipment and machinery pressure monitoring
- Systems subject to vibration or mechanical shock
Compatibility & Replacements
Compatible With
- 1/4″ NPT male threaded pressure ports on hydraulic, pneumatic, and mechanical systems
- Gaseous and liquid media compatible with copper alloy materials
- Control panels and equipment mounting requiring back-mount or lower-mount configurations
