Pressure Gauge Afriso RF 63 AX Ø63 mm 0–10 bar 1/4" Class 2.5 (model 63514)

Afriso RF 63 AX Ø63 mm is a mechanical pressure gauge designed for heating systems. With a 63 mm dial and a measuring range of 0–10 bar, it provides direct, analogue pressure indication for boilers, circulating pumps and hydronic circuits. The gauge uses a 1/4" lower connection and meets accuracy class 2.5, making it suitable for general monitoring and maintenance tasks in residential and light commercial heating installations.

Advantages

The compact Ø63 mm design enables installation in confined spaces and on piping manifolds. Mechanical operation requires no external power source, ensuring continuous measurement even during power interruptions. The 1/4" connection and common accuracy class 2.5 allow straightforward replacement or integration into existing heating systems. Clear dial graduations and robust construction support routine inspection and long-term use in typical heating environments.

Suitable for

• Pressure monitoring on residential boilers
• Integration with circulation pumps and expansion vessels
• Use on hydronic heating manifolds and distribution pipes
• General maintenance checks and system commissioning

Key specifications

• Dial diameter: 63 mm
• Measuring range: 0–10 bar
• Connection type: 1/4" lower (male)
• Accuracy class: 2.5
• Indication: analogue pointer on printed scale
• Operating medium: suitable for non-corrosive gases and liquids commonly used in heating systems

How to use

Install the gauge on a compatible 1/4" threaded port in the heating circuit, ensuring the connection is clean and sealed with appropriate thread sealant or tape. Mount the gauge in a location that permits easy reading of the dial and protects it from mechanical damage and excessive vibration. After installation, pressurize the system and observe the pointer movement to verify correct operation and to set system pressure within the required range. Periodically check the gauge for signs of wear or damage and replace if accuracy is compromised.

Usage recommendations

For accurate readings, avoid installing the gauge where direct exposure to condensate, steam, or corrosive fluids is possible. If installed on systems with aggressive media, use an appropriate isolating diaphragm or a glycerine-filled variant where available. Regular inspection during scheduled maintenance helps ensure reliable pressure monitoring and early detection of leaks or malfunction in heating circuits.
