Pressure gauge OTTONE OT020303, axial 63 mm dial, G¼ male, range 0–10 bar

The OTTONE OT020303 axial pressure gauge features a 63 mm dial and a G¼ male rear connection for direct axial mounting. It measures pressure in the range 0–10 bar and is intended for installation in pipelines, vessels and equipment where a rear (axial) connection provides a compact and reliable pressure indication. The instrument is suitable for monitoring fluid and gas pressure in both hydraulic and pneumatic systems and for routine maintenance checks and process control where a clear analogue reading is required.

Advantages

This axial pressure gauge offers a compact 63 mm dial that delivers clear, easy-to-read analogue readings. The G¼ male axial connection permits direct mounting into process lines or equipment without additional adapters, reducing installation complexity. The 0–10 bar range covers common low- to medium-pressure applications in industrial and commercial settings. The mechanical design provides a simple, maintenance-free visual indicator of system pressure.

Suitable for

• Hydraulic systems requiring visual pressure monitoring
• Pneumatic installations and compressed air systems
• Process lines, tanks and equipment with axial/rear mounting points
• Routine maintenance, inspections and system commissioning

Key specifications

• Dial diameter: 63 mm
• Connection type: axial (rear) G¼ male
• Pressure range: 0–10 bar
• Display: analogue dial with pointer

How to use

Install the gauge by threading the G¼ male connection into a compatible axial port on the pipeline, tank or equipment. Ensure the sealing surface and thread engagement are clean and apply appropriate thread sealant or tape as required by the installation practice. Tighten to the recommended torque for the fitting material to avoid damage. Orient the gauge so the dial is visible for reading; the axial rear connection allows mounting where front or lower ports are not available. After installation, pressurize the system slowly and verify the pointer moves and indicates within the expected range. Periodically check the gauge for mechanical damage, leaks at the connection and for calibration drift.

Usage recommendations

Use the gauge within its specified 0–10 bar range and avoid exposure to pressures above the maximum to prevent permanent damage. Select appropriate sealing materials and mounting torque to prevent leaks and protect the thread. For systems with pulsation or vibration, consider adding a snubber, restrictor or damping element upstream of the gauge to extend service life and improve readability. Replace the gauge if the pointer sticks, shows excessive drift or if the dial glass or case is damaged.
