Pressure gauge Wika 111.10.063 M12x1.5 0–6 bar, plastic case

Mechanical pressure gauge Wika 111.10.063 with M12x1.5 connection and a measuring range of 0–6 bar is designed for monitoring low pressures in hydraulic, pneumatic and HVAC systems. The instrument features a compact plastic case and a clear dial for straightforward reading of system pressure. It is intended for installations where corrosion resistance and a lightweight enclosure are preferred over metal housings.

Advantages

The gauge offers a simple mechanical design that requires no power supply and provides reliable analogue readings. Its plastic case reduces weight and the risk of corrosion in humid environments. The M12x1.5 threaded connection enables compact mounting in confined spaces while the 0–6 bar range allows precise monitoring of low-pressure circuits. The clear dial layout supports quick visual checks of system status.

Suitable for

• Monitoring low-pressure hydraulic circuits
• Pneumatic system pressure checks
• HVAC and refrigeration system pressure monitoring
• Industrial equipment with non-metallic enclosures
• Portable test rigs and service tools

• Case material: plastic
• Display: analogue dial with pointer
• Operating principle: mechanical (Bourdon tube)
• Typical mounting: direct threaded installation
• Application class: low-pressure industrial and commercial use

How to use

Prior to installation, verify system compatibility with a 0–6 bar measuring range and the M12x1.5 thread. Install the gauge by hand-threading into the appropriate port and tighten to the required torque using a suitable wrench or adapter; avoid over-tightening to prevent damage to the plastic case or connection. Position the dial for clear visibility and ensure the system is depressurised during fitting. After installation, pressurise the system slowly and check the pointer movement for smooth operation and absence of leaks around the connection.

Usage recommendations

Use the gauge within its specified pressure range and avoid exposure to aggressive chemicals or prolonged high-temperature conditions that exceed the manufacturer's ambient limits. For applications with vibration or pulsation, consider mounting with appropriate dampening or using a snubber. Periodically inspect the dial and connection for physical damage and recalibrate or replace the instrument if readings drift or the pointer sticks.
