Overview
The WIKA 23X.34 4.5 pressure gauge is a precision Bourdon tube instrument engineered for demanding industrial and process applications. With a robust 316 stainless steel construction and XSEL design, this gauge delivers accurate pressure measurement across a 0–3000 PSI (0–20,000 kPa) range. The 4.5-inch dial face ensures clear, at-a-glance readings, while the 1/2″ NPT lower-mount connection integrates easily into existing systems.
Key Features
- 316 Stainless Steel wetted parts — corrosion resistance for harsh chemical, petrochemical, and offshore environments
- Bourdon tube measuring system — proven accuracy and load-cycle stability per ASME B40.100 Grade 2A
- XSEL process gauge design — engineered to withstand vibration, pulsating pressures, and temperature extremes
- Blow-out back safety case — solid baffle protection on front; media ejection directed rearward
- Acrylic window — clear dial visibility; adjustable pointer for field zeroing

Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The WIKA 23X.34 4.5 series is specified for new installations and can replace other 4.5-inch, 0–3000 PSI process gauges with equivalent 1/2″ NPT connections and 316SS construction.
Works With
- Standard hydraulic and pneumatic systems
- Low-capacity instrumentation networks (analog gauge display only)
- ASME B40.100 compliant measurement infrastructure
